Task: Intent Identification
Input (English): Raloxifene is a selective estrogen receptor (ER) modulator (SERM) used for the treatment of osteoporosis. However, its efficacy and also its safety vary greatly among treated patients, and it might be influenced by the individuals' genetic background. As the receptor activator of the nuclear factor κB (RANK) ligand (RANKL)/RANK/osteoprotegerin (OPG) system is essential for osteoclastogensis and Wnt signaling pathway for osteoblastogenesis, we decided to evaluate the raloxifene treatment in regard to selected polymorphisms in key genes of these two main bone regulatory pathways.", 'Fifty-six osteoporotic postmenopausal women treated with raloxifene were genotyped for 11 polymorphisms located in six genes: -290C>T, -643C>T, and -693G>C in tumor necrosis factor receptor superfamily member 11 (TNFSF11), +34694C>T, +34901G>A, and +35966insdelC in tumor necrosis factor receptor superfamily member 11A (TNFRSF11A), K3N and 245T>G in tumor necrosis factor receptor superfamily member 11B (TNFRSF11B), A1330V in LRP5, I1062V in LRP6, and -1397_-1396insGGA in SOST. For evaluation of treatment efficacy, bone mineral density (BMD) and biochemical markers of bone turnover were measured.', 'One-year change in total hip BMD was associated with +34901G>A in TNFRSF11A (p=0.040), whereas, for lumbar spine BMD, the association was shown for -1397_-1396insGGA in SOST (p=0.015). C-terminal crosslinking telopeptides of type I collagen (CTX) concentrations showed significant association with -643C>T single nucleotide polymorphism (SNP) in TNFSF11 (p=0.049) and +34694C>T in TNFRSF11A (p=0.022). No other association was found between 1-year change in BMDs or biochemical markers and the studied SNPs.
