Bone morphogenetic protein 2 (BMP2) plays an important role in the development of bone and cartilage. It is involved in the hedgehog pathway, TGF beta signaling pathway, and in cytokine-cytokine receptor interaction. It is involved also in cardiac cell differentiation and epithelial to mesenchymal transition. In this study, We expressed human BMP2 (hBMP2) recombinant protein using Baculovirus Expression Vector System (BEVS) in Sf9 insect cells. The hBMP2 cDNA was cloned into baculovirus transfer vector, pBacgus-4x-1 and recombinant baculovirus was screened out through X-gal and GUS-fusions assay. Western blot analysis shown that molecular weight of hBMP2 recombinant protein was about 44.71 kDa.

Allomatrix (Wright Medical Tech, Inc., USA), is a newly designed, injectable putty with a reliable demineralized bone matrix(DBM), derived from human bone. The compound contains 86% DBM and other bone growth factors such as bone morphogenic protein (BMP)-2, BMP-4, insulin-like growth factor (IGF)-1, and transforming growth factor (TGF)-${\beta}1$. It has excellent os-teoinduction abilities. In addition, DBM is known to have osteoconduction capacity as a scaffold due to its collagen matrix. This product contains a powder, which is a mix of DBM and surgical grade calcium sulfate as a carrier. A practitioner can blend the powder with calcium sulfate solution, making a putty-type material which has the advantages of ease of handling, better fixation, and no need for a membrane, because it can function as membrane itself. This study reports the clinical and radiographic results of various guided bone regeneration cases using Allomatrix, demonstrating its strong potential as a graft material.

Dental hygienists handle periodontal tissue every day. Since periodontal tissue contains hard and soft tissue, dental hygienists need to cultivate scientific knowledge about bone tissue. This study introduces recent research results on cells and cytokines related to bone tissue. Recently, bisphosphonate-related osteonecrosis of the jaw has been reported, therefore we would like to present osteoporosis and osteoporosis treatment drugs and their side effects in this study.

Isoflavones have been a central subject in natural phytoestrogens found in Leguminosae. Their effects on bone formation and remodeling are an important turning point in that they can act like estrogen by binding on estrogen receptors on target cell surface. We, therefore, believed that isoflavones may be applied in estrogen deficiency disease such as osteoporosis in terms of estrogen replacement therapy (ERT). As commonly known, osteoporosis is one of hormonal deficiency diseases, especially in menopausal women. (omitted)

Cytokines influence the overall cancer immune cycle by triggering tumor antigen expression, antigen presenting, immune cell priming and activation, effector immune cell recruitment and infiltration to cancer, and cancer killing in the tumor microenvironment (TME). Therefore, cytokines have been considered potential anti-cancer immunotherapy, and cytokine-based anti-cancer therapies continue to be an active area of research and development in the field of cancer immunotherapy, with ongoing clinical trials exploring new strategies to improve efficacy and safety. In this review, we examine past and present clinical developments for major anticancer cytokines, including interleukins (IL-2, IL-15, IL-12, IL-21), interferons, TGF-beta, and GM-CSF. We identify the current status and changes in the technology platform being applied to cytokine-based immune anti-cancer therapeutics. Through this, we discuss the opportunities and challenges of cytokine-based immune anti-cancer treatments in the current immunotherapy market and suggest development directions to enhance the clinical use of cytokines as immuno-anticancer drugs in the future.

Background: TGF-${\beta}$-activated kinase-1 (TAK1) has been found to be over-expressed in a variety of solid malignancies and related to tumor growth. The aim of this study was to evaluate the expression level of TAK1 in clear cell renal cell carcinoma (ccRCC) and assess its value as a novel prognostic marker. Methods: TAK1 mRNA was assessed in 51 paired ccRCC tissues and adjacent normal tissues (ADTs) by real-time PCR. Tissue TAK1 protein was also assessed in 91 ADTs and 177 samples of ccRCC immunohistochemically for evaluation of relationships with clinical characteristics. Results: RT-PCR showed that TAK1 RNA level was significantly higher in ccRCC tissues than in the paired ADTs and immunohistochemistry confirmed higher expression of TAK1 protein in ccRCC samples compared with ADTs. TAK1 protein expression in 177 ccRCC samples was significantly correlated with T stage, N classification, metastasis, recurrence and Fuhrman grade, but not age and gender. Patients with low TAK1 levels had a better survival outcome. TAK1 expression and N stage were independent prognosis factors for the overall survival of ccRCC patients. Conclusions: Overexpression of TAK1 predicts a poor prognosis in patients with ccRCC, so that TAK1 may serve as a novel prognostic marker.

Objectives This study was carried out to investigate the effect of Ganoderma lucidum extract (GLE) and microneedle therapy system (MTS) on hair growth in an alopecia model of C57BL/6N mice. Methods Five-week old mice were depilated and separated in 4 groups ; CON (50% EtOH), MXD (5% Minoxidil), MTS and GLE + MTS. The treatments were applied twice a week for 3 weeks. The hair growth was determined photographically, the hair density, thickness and length were identified by Folliscope and the weights of body and organs were measured. In dorsal skin tissue, the expression of hair growth-related gene and protein was analyzed by RT - PCR or Western blot. In addition, the hair follicles in the dermis were observed by H&E staining. Results The promotion of hair growth was observed in GLE + MTS and MTS compared to CON. The hair density, thickness and length were also improved in GLE + MTS and MTS compared to CON. The mRNA expression of TGF-${\alpha}$, TGF-${\beta}1$, IGF-1, PRL and PL and the protein expression of VEGF and IGF-1 were increased in GLE + MTS and MTS compared to CON. The hair follicles and hair root growth were improved in GLE + MTS and MTS compared to CON. In the above results, GLE + MTS were more effective than MTS. Conclusions These results suggest that GLE and MTS has a hair growth activity and can be useful for the treatment of alopecia.
