[Advances of Claudin6-targeting drugs in cancer therapy].

CLDN6 is a member of the CLDNs family that is specifically and highly expressed in cancers such as ovarian, testicular, endocervical, liver and lung adenocarcinoma, but hardly expressed in adult normal tissues. CLDN6 is able to activate multiple signaling pathways, which take part in the development and progression of cancer, including promoting tumor growth, migration and invasion, and promoting chemoresistance in cancer. In recent years, CLDN6 has received much attention as a novel target for cancer therapeutics. Many types of anticancer drugs targeting CLDN6 have been developed, including antibody-conjugated drugs (ADC), monoclonal antibodies, bispecific antibodies, and chimeric antigen receptor T-cell immunotherapy (CAR-T). This paper briefly summarizes the structure, expression and function of CLDN6 in tumors, and reviews the current status and ideas of developing targeted CLDN6 anticancer drugs.

Effects and dose-response relationships of exercise intervention on weight loss in overweight and obese children: a meta-regression and system review.

The aim of this study was to determine the effect of different exercise doses on weight loss in obese/overweight children. PubMed, Embase, SPORTDiscus, and the Cochrane library were searched from inception to November 2020 for randomized controlled trials. Fourty six trials involving 2,599 obese/overweight children were finally included. Different exercise dose interventions had different impacts. Exercise intervention reduce body weight (BW) by 1.46 kg (95% CI, -2.35 to -0.56, p=0.001), body fat percentage (BF%) by 2.24 (95% CI, -2.63 to -1.84, p<0.001) and body mass index (BMI) by 1.09 kg/m2 (95% CI, -1.45 to -0.73, p<0.001). Each MET-h/week was association with 0.147 kg (95% CI, -0.287 to -0.007, p=0.039) decrease in BW, 0.060 (95% CI, -0.118 to -0.002, p=0.042) decrease in BF%, and 0.069 kg/m2 (95% CI, -0.125 to -0.014, p=0.015) decrease in BMI. The findings suggest that there is a positive liner between exercise dose and weight loss, each MET-h/week associated with 0.147 kg, 0.060 and 0.069 kg/m2 decrease in body weight, BF%, BMI, respectively.
