Objectives To observe influences of two functionally important polymorphisms (5'-UTR and 3 -UTR) in thymidylate synthase (TS) gene and their combinative effects with drinking on the susceptibility of colorectal cancer (CRC). Methods A case-control study was designed, which included 140 CRC patients and 343 control subjects. Risk of CRC was estimated by unconditional Logistic model. Results The genotype distributions of the polymorphisms did not show significant differences between the cases and the controls. However, in those with -6 bp/-6 bp genotypes, the 2R carriers had a decreased risk (OR = 0. 60, 95%CI, 0. 23-1. 52) , but in +6 bp carriers, the 2R carriers had an elevated risk (OR=1. 87, 95%CI, 0. 94-3. 72). The likelihood test revealed the interaction existed between these two polymorphisms (P for interaction = 0. 05). Moreover, the combinative effect between the 3 -UTR polymorphism and alcohol drinking showed a significant association with the susceptibility of CRC (P for interaction =0. 01). In non-drinkers, the-6 bp allele carriers had a significant decreased risk (OR = 0. 57, 95%CI, 0. 32-0. 99) , but in ever and current drinkers, the +6 bp allele (6-bp insertion) carriers had an elevated risk (OR=1. 88, 95%CI, 0. 80-4. 41) , in which OR values ascended with the prolongation of drink-time. Conclusions The polymorphisms of thymidylate synthase at 5'-UTR and 3'-UTR may not be regarded as independent predictive factors for the susceptibility of CRC. However, interactions exist in these two polymorphisms and between the 3'-UTR polymorphism and drinking. Further studies with larger sample size and in different ethnic groups are needed.

Ovarian cancer bears the highest mortality in gynecologic cancer, and its 5-year survival rate is about 30%. Although 70% to 80% ovarian cancer is epithelial origin, increasing evidence indicates that reciprocal interactions between tumor cells and various types of stromal cells also play important roles in driving ovarian tumor progression and that these stromal cells represent attractive therapeutic targets. This review discusses the biological signiifcance of the cross-talk between ovarian cancer cells and three major types of stromal cells (endothelial cells, ifbroblasts and macrophages) and the development of new-generation therapies that target the ovarian tumor micro-environment.

Transforming growth factor-β is an important cytokine with various bioactivities, including embryonic development, wound healing, chemotaxis and cell cycle regulation. Epithelial-mesenchymal transition (EMT) is the main pathway of tumor cell to obtain the ability of invasion and metastasis. The TGF-β is the key factor known to induce EMT in cancer cells and plays an important role in the process. In recent years, some progress has been obtained. Some TGF-β inhibitors have approved in the market or in clinical trials. TGF-β inhibitors can play an important role on the treatment of tumors, glaucoma, liver and kidney fibrosis disease and scar repair. Novel TGF-β inhibitors reported in recent years were reviewed in this article.

BACKGROUND: Osteoporosis is a serious threat to the health and quality of life in the elderly. It is important to establish an ideal experimental animal model to study the etiology and treatment of osteoporosis.OBJECTIVE: To establish a rat model of osteoporosis induced by different dosages of retinoic acid, thus selecting the optimal dosage.METHODS: Eighty female Sprague-Dawley rats were randomly divided into control, low-, middle- and high-dosage groups based on body mass (n=20 per group), The rats in the latter three groups were induced with 80, 100, and 120 mg/(kg?d) retinoic acid via gastric lavage for 14 days.RESULTS AND CONCLUSION: Compared with the control group, the bone mineral density, number of osteoblasts and osteoclasts, and bone microarchitecture in the low-dosage group showed no significant changes, while there were significant decrease in the serum level of calcium and bone mineral density of femur, significant increase in the number of osteoclasts at the femur and significant changes in the femoral microarchitecture in the middle- and high-dosage groups, especially in the middle-dose group. To conclude, 120 mg/(kg?d) retinoic acid via gastric lavage for 14 days can induce a stable osteoporosis model in rats.
