  • BET inhibitor, as an epigenetic regulator inhibitor, reduces the expression of oncogenes such as Myc and Bcl-2, which affects cancer growth and development. However, it has modest activity because of the narrow therapeutic index. Therefore, combination therapy is necessary to increase the anti-tumor effect. Paclitaxel, an anti-mitotic inhibitor, is used as second-line therapy for gastric cancer (GC) as a monotherapy or combination. In this study, we performed RNA sequencing of GC cells treated with iBET-151 and/or paclitaxel to identify the differentially expressed genes associated with possible mechanisms of synergistic effect. We also performed Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses to determine the most enriched terms and pathways of upregulated and downregulated genes. We found 460 genes in which iBET-151 and paclitaxel combination treatment changed more than single-treatment or no-treatment. Thus, additional functional studies are needed, but our results provide the first evidence of the synergistic effect between iBET-151 and paclitaxel in regulating the transcriptome of GC cells.

  • Fluorouracil (5-FU) is one of the most widely used chemotherapeutic drugs in the treatment of advanced colorectal cancer patients. Capsaicin (N-vanillyl-8-methyl-alpha-nonenamide), a spicy component of hot pepper, is a homovanillic acid derivative that preferentially induces cancer cells to undergo apoptosis. The purpose of the present study is to examine whether capsaicin enhances the anticancer effect of 5-fluorouracil in HT-29 human colon cancer cells by inducing apoptosis, and whether PPARgamma is involved in the capsaicin action in combination treatment with 5-FU. Treatment of the cells with either 5-FU or capsaicin alone for 48 h had little effect on the cell viability up to $50{\mu}M$ concentration, whereas co-treatment of the cells with capsaicin in the presence of 5-FU for 48 h significantly decreased the cell viability in a concentration-dependent manner. In addition, caspase-3 activity, a marker enzyme for apoptosis, was significantly increased by the combined treatment with 5-FU and capsaicin compared to the 5-FU or capsaicin alone treatment. Also, treatment with troglitazone, a peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$) agonist, further enhanced the effect of the combination treatment on the cell viability and caspase-3 activity, and bisphenol A diglycidyl ether (BADGE), a $PPAR{\gamma}$ antagonist, blocked the effect of the combination treatment. These results suggest that the combination treatment of HT-29 cells with 5-FU and capsaicin induces apoptotic cell death at relatively low concentration than each drug alone, and the combination treatment may be associated with the $PPAR{\gamma}$ pathway activation.

  • Objectives : In this study, we investigated the combination effects of Cinnamomi cortex Ethanol Extract (CcEE) and hyperthermia in the human AGS gastric cancer cell line. Methods : AGS cells were treated with the indicated concentrations of CcEE (0, 50 or $60{\mu}g/mL$) for 1h prior to hyperthermia. And then incubated for a further 30 min at the indicated temperatures (37, 42 or $43^{\circ}C$) in a humidified incubator containing 5% $CO_2$ or a thermostatically controlled water bath for hyperthermia. The cell viability was measured by MTT assay, Morphology assay and Trypan blue assay. To investigate the possible molecular signaling pathways, the activation of mitogen-activated protein kinase (MAPK) proteins (ERK, p38 and JNK) and expression of various anti-apoptotic proteins such as Caspase-3, Caspase-9, p53, Cyclin D1 and MMP-2 were assessed by Western blot analysis. In addition, Annexin V and 7-amino-actinomycin D (7-AAD) staining was performed to examine the apoptotic mechanism. Results : Combination of CcEE with hyperthermia effectively suppressed the cell viability and changed cellmorphology compared with CcEE or hyperthermia treatment alone. Combined treatment also abated the expression of Caspase-3, Caspase-9, Cyclin D1 and MMP-2. Whereas, the expression level of p53 was up-regulated by co-treatment. Moreover, combination treatment enhanced phosphorylation of ERK, p38 and JNK. In addition, this combination increased anti-cancer effect by inducing cell death through the apoptosis. Conclusions : Taken together, all these findings suggest that the combination treatment with CcEE and hyperthermia may have therapeutic potential as a promising approach to patients with stomach cancer.

  • Among a number of factors related to the effect of acupuncture and moxibustion treatment, prescriptions do important work. Traditional eastern doctors also placed emphasis on prescriptions of acupuncture and moxibustion, and a lot of experiences have been accumulated. The method forms prescriptions of Sa-am acupuncture therapy pivots on five transport points. Studies show prescriptions are made on the basis of the theory of 'Wang Xiang Xiu Qiu Si'(旺相休囚死) used engendering and restraining of five phases, and it is considered the principle of transformed prescriptions through this theory. Because there is still no study analyzing prescriptions of Sa-am acupuncture by existing principles, we report opinion about Combination principle of points in them. 1. We studied history of acupuncture and moxibustion, development and kinds of points' Combination principle. 2. Around Combination principles of points in Classic of Difficult Issues and Internal Classic, we analyzed and compared between Combination principles of points in Sa-am acupuncture therapy and them in Korea and overall acupuncture methods. 1. There were many Combination principles of acupunture point combination in Classic of Difficult Issues, Internal Classic and Korea acupuncture methods. For example, Point combination of the same meridian, Point combination of the different meridian, Exterior-Interior point combination, Point combination of the same name meridian, Point combination of the multiple meridian, Point combination of Adjacent and Distant points, Left-Right point combination, Anterior-Posterior point combination, Superior-Inferior point combination, Brook point and Stream point combination, Triple energizer point combination, Eight meeting point combination, Five transport point combination, Source-Connecting point combination, Alram point and Transport point combination, Mother-Sun meridian combination, Empirical point combination, Important point combination, Point combination according to syndrome. 2. Existing Combination principles of points in prescriptions of Sa-am acupuncture therapy included every rule. 3. They could be evidences that prescriptions of Sa-am acupuncture therapy are forms inheriting and developing acupuncture and moxibustion treatments.

  • Cisplatin is one of the most effective antitumor agents currently available for cancer therapy. However, its clinical use has been limited by its severe side effects, especially nephrotoxicity. Therefore, brazilin, which has a radical scavenging effect, was given intraperitoneally to evaluate the effect on cisplatin nephrotoxicity in rats. Remarkable protective effects against nephrotoxicity of cisplatin were observed when brazilin was administered to rats simultaneously with cisplatin. Hepatotoxicity induced by combination treatment of cisplatin and brazilin was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase. Combination treatment did not affect the levels of sGPT and SGOT, and any combination treatment did not induce metallothionein in kidney. Brazilin which has radical scavenging effect directly reduced nephrotoxicity of wisplatin in vivo. Thus, it seems that nephrotoxicity of cisplatin was caused by free radicals. The present results Indicate that brazilin, when it is given with cisplatin, may provide protection against cisplatin nephrotoxicity in rats.

  • Wound healing and antibacterial effects of solcoseryl-micronomicin combination gel on an open wound were studied in mice. A simple model was designed for assessing the effects. Using the model, we compared the efficacy of a combined topical gel of solcoseryl and micronomicin with those gels of solcoseryl or micronomicin alone. From the results of our experiment, the wound healing effect of open wounds by treatment with the combination gel was significantly enhanced when compared with those by treatment with solcoseryl gel or micronomicin gel alone. And the antibacterial effect of the combination gel was higher than those of solcoseryl gel or micronomicin gel alone.

  • This study was designed to investigate the protective effect of the combination of fucoidan and lutein against AAPH-induced oxidative stress in THP-1 cells. The combination of fucoidan and lutein existed significant antioxidant effect on AAPH-damaged THP-1 cells by using lipid peroxidation and cellular antioxidant capacity assay. Fucoidan($1\;{\mu}g/m{\ell}$) and lutein($10\;{\mu}g/m{\ell}$) did not affect at all the viability of THP-1 cells, but protected the AAPH-damage of THP-1 cells at the same concentration. The viability of THP-1 cells was 0% with 1 mM AAPH alone, the protective effect of fucoidan($1\;{\mu}g/m{\ell}$) and lutein($10\;{\mu}g/m{\ell}$) was 37% and 36%, respectively. The combination of fucoidan($1\;{\mu}g/m{\ell}$) and lutein($10\;{\mu}g/m{\ell}$) exhibited significant inhibitory effect of lipid peroxidation using TBARS assay and cellular antioxidant capacity using DCFH-DA assay. In lipid peroxidation, the TBARS value of 1 mM AAPH alone was $0.8{\pm}0.03\;nM$ MDA, its of the combination of fucoidan($1\;{\mu}g/m{\ell}$) and lutein($10\;{\mu}g/m{\ell}$) was $0.2{\pm}0.05\;nM$ MDA. In cellular antioxidant capacity, the combination of fucoidan($1\;{\mu}g/m{\ell}$) and lutein($10\;{\mu}g/m{\ell}$) exhibited significant cellular antioxidant capacity of 76%, whereas quercetin($10\;{\mu}M$) as positive control exhibited the cellular antioxidant capacity of 32%. These results indicate that the cotreatment of fucoidan and lutein protects against AAPH-induced THP-1 cell damage by inhibiting lipid peroxidation, increasing cellular antioxidant capacity.
