Objective : Hypothyroidism is a syndrome characterized by symptoms such as cold intolerance, or weight gain. Because of side effects of Western medicine treatment, interest in oriental medicine has been increasing. In this study, we examined the therapeutic effects of Evodiae fructus and histological modification in hypothyroidism rat model induced by PTU(6-propyl, 2-thiouracil). Methods : After inducing hypothyroidism in the rats by PTU injections, we divided the rats into four groups, the Evodiae fructus 100 500, control, and $LT_4$ (levothyroxine) groups. After 2 weeks Evodiae fructus and $LT_4$ were administered, respectively. The weight was measured once a week. After sampling the blood for biochemical analysis to check the levels of $T_3$, $T_4$ and TSH, the thyroid tissue was removed, stained with H&E, and an image was obtained using an optical microscope. Results : Compared with normals, controls showed low $T_4$ and high TSH. The Evodiae fructus group showed a statistically meaningful $T_3$ increase to be dose related. But the levels of TSH showed no meaningful difference between the Evodiae fructus group and normals. About the biochemical tests(liver, kidney etc) and weight change, there was no meaningful difference between the Evodiae fructus group and controls. In the biopsy, the Evodiae fructus group showed thyroid tissue improvement compared to controls. Conclusions : These results show that Evodiae fructus stimulates the decreased functions of the thyroid, and also has thyroid cell protecting effects. The lab results also showed that Evodiae fructus is a safe substance that doesn't cause hepatotoxicity or nephrotoxicity. Therefore it is an effective substance in the treatment of hypothyroidism.

Background and Objectives: Osteoarthritis (OA) is a degenerative disease that leads to the progressive destruction of articular cartilage. Current clinical therapeutic strategies are moderately effective at relieving OA-associated pain but cannot induce chondrocyte differentiation or achieve cartilage regeneration. We investigated the ability of wedelolactone, a biologically active natural product that occurs in Eclipta alba (false daisy), to promote chondrogenic differentiation. Methods and Results: Real-time reverse transcription-polymerase chain reaction, immunohistochemical staining, and immunofluorescence staining assays were used to evaluate the effects of wedelolactone on the chondrogenic differentiation of mesenchymal stem cells (MSCs). RNA sequencing, microRNA (miRNA) sequencing, and isobaric tags for relative and absolute quantitation analyses were performed to explore the mechanism by which wedelolactone promotes the chondrogenic differentiation of MSCs. We found that wedelolactone facilitates the chondrogenic differentiation of human induced pluripotent stem cell-derived MSCs and rat bone-marrow MSCs. Moreover, the forkhead box O (FOXO) signaling pathway was upregulated by wedelolactone during chondrogenic differentiation, and a FOXO1 inhibitor attenuated the effect of wedelolactone on chondrocyte differentiation. We determined that wedelolactone reduces enhancer of zeste homolog 2 (EZH2)-mediated histone H3 lysine 27 trimethylation of the promoter region of FOXO1 to upregulate its transcription. Additionally, we found that wedelolactone represses miR-1271-5p expression, and that miR-1271-5p post-transcriptionally suppresses the expression of FOXO1 that is dependent on the binding of miR-1271-5p to the FOXO1 3'-untranscribed region. Conclusions: These results indicate that wedelolactone suppresses the activity of EZH2 to facilitate the chondrogenic differentiation of MSCs by activating the FOXO1 signaling pathway. Wedelolactone may therefore improve cartilage regeneration in diseases characterized by inflammatory tissue destruction, such as OA.

Long-chain polyunsaturated fatty acids (LC-PUFA) promote the development of brain and vision of the fetus, relieve inflammation, inhibit oral dysplasia of rumor cell, decrease the incidence of cardiovascular disease and regulate arrhythmia. ${\Delta}-6$ desaturase is the rate-limited enzyme in the desaturation process. This study reports the cloning, characterization and tissue expression of a ${\Delta}-6$ desaturase gene in the chicken. PCR primers were designed based on the predicted sequence of chicken ${\Delta}-6$ desaturase (accession number: XM421053) and used to isolate a cDNA fragment of 1,323 bp from chicken liver. Based on the 1,323 bp fragment an EST (BI390105) was obtained by BLAST. The EST and 5'nd of the 1,323 bp fragment were partially overlapped. Gene specific primers derived from the EST were used for amplification of the 5'nd. Another gene-specific primer derived from the 1,323 bp fragment was used for amplification of the 3'nd by 3'ACE. Then the three overlapping cDNA sequences obtained were assembled with DNAMAN software and a full-length ${\Delta}-6$ desaturase of 2,153 bp was obtained. The full-length cDNA contained an ORF of 1,335 bp with a 5'ntranslated region of 147 nucleotides followed by an ATG initiation codon. Stop codon TGA was at position 1,481-1,483 bp. The deduced amino acids shared an homology above 77% with bovine, mice, orangutan, rat and human. The protein sequence had three histidine-rich regions HDFGH (HisI region), HFQHH (HisII region) and HH (HisIII region), a cytochrome $b_{5}$-like domain containing a heme-binding motif and two transmembrane domains. Sequence analysis of the chicken genomic DNA revealed that the coding sequence of chicken ${\Delta}-6$ desaturase included 12 exons and 11 introns. Semi-quantitative RT-PCR showed that the ${\Delta}-6$ desaturase expression levels were in turn liver, spleen, pancreas, lung, breast muscle, heart, and abdominal fat. The expression of ${\Delta}-6$ desaturase in liver was significantly higher than that in breast muscle (p<0.01). The expression of ${\Delta}-6$ desaturase in lung was significantly higher than that in abdominal fat (p<0.01). This is the first clone of chicken ${\Delta}-6$ desaturase.

Objectives : The purpose of this study is to investigate Acute and Subacute Toxicity, and Anti-cancer Effect of H Herbal-acupuncture on mice and rats. Methods : Balb/c mice were injected intraperitoneally with H Herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were experimented in the same way for subacute toxicity test. H Herbal-acupuncture was injected into abdomen of mice having S-180 cancer cell line. Result : 1. During the test, $LD_{50}$ could not be counted since there was no expired subjects. 2. In an acute toxicity test, the loss of motility and reflex action was observed, but weight increased in the treatment group, compared with those in the normal group (P<0.05). 3. In an acute toxicity test of serum biochemical values of mice, glucose increased in the treatment group II while total cholesterol was increased in the all treatment groups (P<0.05). 4. In a subacute toxicity test, a little loss of motility and reflex action was observed in the treatment group. Weight of mice in the treatment group decreased on the 28th day. 5. In a subacute toxicity test, liver weight was decreased but lung weight of mice increased in the all treatment groups (P<0.05). 6. As a result of measuring Complete Blood Count test (CBC) of rat, HCT was decreased in treatments even though it was not significant, compared with the normal group (P<0.05). 7. In a serum biochemical value test of subacute toxicity, total protein and albumin decreased in the all treatment groups. Creatinine, glucose, GOT increased in the treatment group I compared with the control group. Alkaline phos-phatase decreased in treatment II group, compared with the control group (P<0.05). 8. Median survival time that was measured in the rats treated with sarcoma-180 cancer cell Median decreased in the treatment group, compared with the control group (P<0.05). 9. Natural killer cell activity showed significant reduction at 100:1 and 10:1 E/T ratio while it increased at 50:1 E/T ratio. It is inferred that there was an error in the experiment (P<0.05). 10. In an interleukin-2 productivity test, even though it decreased in lung cancer, and increased in abdomen cancer, but it was only a small difference (P<0.005). 11. After injecting B16F10 cell into a capillary vessel of C57BL/6 mice and generating metastasized lung cancer, the lung was examined with the naked eye. It was not possible to see metastasized cancer in the all groups on the seventh day but the cancer was viewed on the fourteenth day. The number and volume of metastasized cancer in the treatment group enlarged in the treatment group, compared with the control group. Conclusion : According to the results, H herbal-acupuncture took no effects in cancer.

Tumor necrosis factor-${\alpha}$(TNF), a polypeptide hormone secreted primarily by activated macrophages, was originally identified on the basis of its ability to cause hemorrhagic necrosis and tumor regression in vivo. Subsequently, TNF has been shown to be an important component of the host responses to infection and cancer and may mediate the wasting syndrome known as cachexia. These systemic actions of TNF are reflected in its diverse effects on target cells in vitro. TNF initiates its diverse cellular actions by binding to specific cell surface receptors. Although TNF receptors have been identified on most of animal cells, regulation of these receptors and the mechanisms which transduce TNF receptor binding into cellular responses are not well understood. Therefore, in the present study, the mechanisms how TNF receptors are being regulated and how TNF receptor binding is being transduced into cellular responses were investigated in rat liver plasma membranes (PM) and ME-180 human cervical carcinoma cell lines. $^{125}I$-TNF bound to high ($K_d=1.51{\pm}0.35nM$)affinity receptors in rat liver PM. Solubilization of PM with 1% Triton X-100 increased both high affinity (from $0.33{\pm}0.04\;to\;1.67{\pm}0.05$ pmoles/mg protein) and low affinity (from $1.92{\pm}0.16\;to\;7.57{\pm}0.50$ pmoles/mg protein) TNF binding without affecting the affinities for TNF, suggesting the presence of a large latent pool of TNF receptors. Affinity labeling of receptors whether from PM or solubilized PM resulted in cross-linking of $^{125}I$-TNF into $M_r$ 130 kDa, 90 kDa and 66kDa complexes. Thus, the properties of the latent TNF receptors were similar to those initially accessible to TNF. To determine if exposure of latent receptors is regulated by TNF, $^{125}I$-TNF binding to control and TNF-pretreated membranes were assayed. Specific binding was increased by pretreatment with TNF (P<0.05), demonstrating that hepatic PM contains latent TNF receptors whose exposure is promoted by TNF. Homologous up-regulation of TNF receptors may, in part, be responsible for sustained hepatic responsiveness during chronic exposure to TNF. As a next step, the post-receptor events induced by TNF were examined. Although the signal transduction pathways for TNF have not been delineated clearly, the actions of many other hormones are mediated by the reversible phosphorylation of specific enzymes or target proteins. The present study demonstrated that TNF induces phosphorylation of 28 kDa protein (p28). Two dimensional soidum dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) resolved the 28kDa phosphoprotein into two isoforms having pIs of 6.2 and 6.1. The pIs and relative molecular weight of p28 were consistent with those of a previously characterized mRNA cap binding protein. mRNA cap binding proteins are a class of translation initiation factors that recognize the 7-methylguanosine cap structure found on the 5' end of eukaryotic mRNAs. In vitro, these proteins are defined by their specific elution from affinity columns composed of 7-methylguanosine 5'-triphosphate($m^7$GTP)-Sepharose. Affinity purification of mRNA cap binding proteins from control and TNF treated ME-180 cells proved that TNF rapidly stimulates phosphorylation of an mRNA cap binding protein. Phosphorylation occurred in several cell types that are important in vitro models of TNF action. The mRNA cap binding protein phosphorylated in response to TNF treatment was purifice, sequenced, and identified as the proto-oncogene product eukaryotic initiation factor-4E(eIF-4E). These data show that phosphorylation of a key component of the cellular translational machinery is a common early event in the diverse cellular actions of TNF.

Growth hormone (GH) plays a key role in regulating postnatal growth and can stimulate growth of animals by acting directly on specific receptors on the plasma membrane of tissues or indirectly through stimulating insulin-like growth factor (IGF)-I synthesis and secretion by the liver and other tissues. IGF-I and IGF-Ⅱ are polypeptides with structural similarity with proinsulin that stimulate cell proliferation by endocrine, paracrine and autocrine mechanisms. The initial event in the metabolic action of IGFs on target cells appears to be their binding to specific receptors on the plasma membrane. Current evidence indicates that the mitogenic actions of both IGFs are mediated primarily by binding to the type I IGF receptors, and that IGF action is also mediated by interactions with IGF-binding proteins (IGFBPs). Six distinct IGFBPs have been identified that are characterized by cell-specific interaction, transcriptional and post-translational regulation by many different effectors, and the ability to either potentiate or inhibit IGF actions. Nutritional deficiencies can have their devastating consequence during growth. Although IGF-I is the major mediator of GH's action on somatic growth, nutritional status of an organism is a critical regulator of IGF-I and IGFBPs. Various nutrient deficiencies result in decreased serum IGF-I levels and altered IGFBP levels, but the blood levels of GH are generally unchanged or elevated in malnutrition. Effects of protein, energy, vitamin C and D, and zinc on serum IGF and IGFBP levels and tissue mRNA levels were reviewed in the text. Multiple factors are involved in the regulation of intestinal epithelial cell growth and differentiation. Among these factors the nutritional status of individuals is the most important. The intestinal epithelium is an important site for mitogenic action of the IGFs in vivo, with exogenous IGF-I stimulating mucosal hyperplasia. Therefore, the IGF system appears to provide and important mechanism linking nutrition and the proliferation of intestinal epithelial cells. In order to study the detailed mechanisms by which intestinal mucosa is regulated, we have utilized IEC-6 cells, an intestinal epithelial cell line and Caco-2 cells, a human colon adenocarcinoma cell line. Like intestinal crypt cells analyzed in vivo or freshly isolated intestinal epithelial cells, IEC-6 cells and Caco-2 cells possess abundant quatities of both type Ⅰ and type Ⅱ IGF receptors. Exogenous IGFs stimulate, whereas addition of IGFBP-2 inhibits IEC-6 cell proliferation. To investigate whether endogenously secreted IGFBP-2 inhibit proliferation, IEC-6 cells were transfected with a full-length rat IGFBP-2 cDNA anti-sense expression construct. IEC-6 cells transfected with anti-sense IGFBP-2 protein in medium. These cells grew at a rate faster than the control cells indicating that endogenous IGFBP-2 inhibits proliferation of IEC-6 cells, probably by sequestering IGFs. IEC-6 cells express many characteristics of enterocyte, but do not undergo differentiation. On the other hand, Caco-2 cells undergo a spontaneous enterocyte differentiation. On the other hand, Caco-2 cells undergo a spontaneous enterocyte differentiation after reaching confluency. We have demonstrated that Caco-2 cells produce IGF-Ⅱ, IGFBP-2, IGFBP-3, and an as yet unidentified 31,000 Mr IGFBP, and that both mRNA and peptide secretion of IGFBP-2 and IGFBP-3 increased, but IGFBP-4 mRNA and protein secretion decreased after the cells reached confluency. These changes occurred in parallel to and were coincident with differentiation of the cells, as measured by expression of sucrase-isomaltase. In addition, Caco-2 cell clones forced to overexpress IGFBP-4 by transfection with a rat IGFBP-4 cDNA construct exhibited a significantly slower growth rate under serum-free conditions and had increased expression of sucrase-isomaltase compared with vector control cells. These results indicate that IGFBP-4 inhibits proliferation and stimulates differentiation of Caco-2 cells, probably by inhibiting the mitogenic actions of IGFs.

Antioxidants and antioxidants with somatic cell co-culture, bovine oviduct epithelial cells(BOEC) and buffalo rat liver cells(BRLC), were studied as a mean of increasing the development and intracellular glutathione(GSH) concnetrations of bovine embryos derived from in vitro matured(IVM) and in vitro fertilized(IVF) oocytes. Cell numbers and intracellular GSH concentrations of blastocysts were also counted. The developmental rate beyond morula stages in CRlaa containing taurine(2.5mM), superoxide dismutase(SOD, 600U) and catalase(250U) were 1%, 75.0%, 64.8% and 62.3%, respectively. The developmental rate in antioxidant groups was significantly higher than in control(P<0.05). The intracellular GSH concentrations of blastocysts cultured in 0, 2.5mM taurine, 600U SOD and 250U catalase were 33.8pM, 39.3pM, 42.3pM and 54.8pM, respectively. This result indicated that the developmental rates and intracellular GSH concentrations of catalase group was significantly higher than any other groups(P<0.05). The developmental capacity in CRlaa plus various antioxidants co-cultured with BOEC were 55.3%(control), 74.1%(2.5mM taurine), 66.7%(600U SOD) and 70.7%(250U catalase) and in CRlaa plus various antioxidants co-cultured with BRLC in control, 2.5mM taurine, 600U SOD and 250U catalase were 63.8%, 75.5%, 71.0% and 73.5%, respectveily, the intracellular GSH concentrations of blastocyst embryos co-cultured with BOEC and BRLC in CRlaa with 0.25mM taurine, 600U SOD and 250U catalase were 73.4pM and 64.4pM, 79.9pM and 67.5pM, 82.3pM and 71.7pM, and 83.0pM and 80.0pM, respectively. Cell numbers of blastocysts were not difference in all experimental groups. These studies indicate that andtioxidants and antioxidant with somatic cell co-culture can increase the proportion of embryo that developed into morula and blastocysts, and the intracellular GSH concentrations of blastocyst embryos.

간독성물질인 $CCl_4$의 대사에서 반응성이 높은 대사중간체의 증가가 P450 2E1의 활성 및 발현증가와 관련된다. YH439는 랫트에서 사염화탄소에 의하여 유발된 간 손상에 보호효과가 탁월하였고, 각종 독성물질에 의하여 발생하는 간염을 억제하며 P450 2E1의 발현을 억제하는 것으로 나타났다. P450 2E1의 발현억제가 YH439의 간장보호작용의 일부기전으로 해석되나 free radical 공격의 제어, 방어과정에 관련된 탐식세포의 역할등 간장독성에 관련된 YH439의 영향 및 관련된 기초연구는 완전히 확립되어 있지 않다. 본 연구에서는 상승적인 화학적 독성에 대한 YH439의 보호효과를 관찰하였다. Retinoyl palmiate (Vit-A)를 전처러하고 YH439를 처리한 rat의 경우 $CCl_4$ 단독투여군에 비하여 혈장 alanine aminotransferase (ALT)활성이 5배로 증가하여 $CCl_4$에 의한 간독성을 현저히 강화시켰으나, YH439와 Vit-A를 동시에 전처리한 rats에 있어서는 Vit-A에 의하여 강화된 독성이 94% 감소하였다. Vit-A에 의한 혈장 ALT 활성 증가는 Kupffer cell 활성을 선택적으로 억제하는 $GdCl_3$의 투여에 의해 완전히 차단되어 YH439가 Kupffer cell 활성억제를 매개로 상승적 간손상에 대하여 보호효과가 있음을 지지한다. Propyl sulfide의 전처치는 $CCl_4$에 의해 유도되는 간독성을 $CCl_4$ 단독투여와 비교했을때 5배 이상 증가시켰으나, Propyl sulfide와 YH439를 병용투여할 경우 propyl sulfide에 의해 강화되는 간독성이 YH439의 투여용량에 의존적으로 감소하였고, propyl sufide와 $CCl_4$에 의한 지질과산화의 증가가 YH439에 의하여 용량의존적으로 억제되는 것으로 나타났다. Propyl sulfide에 의하여 강화된 간독성의 차단은 YH439가 P450 2E1 발현조절을 통하여 간독성을 제어함을 지지한다. 그러나 YH439는 pyridine과 $CCl_4$에 의한 독성을 억제시키지 못하였다. 이는 Pyridine에 의해 유도되는 다른 형의 P450발현이 YH439에 의해 억제되지 못하는 이유로 해석된다. 중금속에 의해 유도되는 간독성에 대한 YH439의 보호효과를 ICR mice에서 관찰하였을 때 $CdCl_2$를 1회 투여할때 ALT와 aspartate aminotransferase (AST)활성이 $5{\sim}6$배 증가하였으나 YH439를 투여한 후 $CdC1_2$를 투여한 동물에 있어서는 투여후 6시간에 AST의 증가가 유의성 있게 억제되었다. 그러나 YH439는 thioacetamide에 의하여 유발된 liver fibrosis에는 개선효과가 없는 것으로 나타났다. 이러한 결과는 YH439가 Kupffer cell 불활성화를 통하여 Vit-A에 의해 유도되는 간독성을 효과적으로 방어하고, YH439에 의한 P450 2E1의 발현억제는 propyl sulfide를 경유하는 간독성 차단과 관계되며, YH439는 중금속으로 유도된 조직독성에 방어효과가 있음을 지지한다.
