骨质疏松药物可提高胰腺癌患者生存率!

2015-11-07 QQduhq 译 MedSci原创

在11月5-9日举行的AACR-NCI-EORTC分子靶向国际会议上,研究人员表示,Bazedoxifene——一种经FDA批准可用于治疗并预防骨质疏松症的药物可用来抑制胰腺肿瘤的生长(通过抑制IL-6/STAT3信号通路以抑制癌细胞的生长和繁殖)。 美国俄亥俄州立大学综合癌症中心儿科副教授Jiayuh Lin博士表示,2015年美国约有5万人被诊断患有胰腺癌,但是仅有不到5%的胰腺癌患者的生存年

美国俄亥俄州立大学综合癌症中心儿科副教授Jiayuh Lin博士表示,2015年美国约有5万人被诊断患有胰腺癌,但是仅有不到5%的胰腺癌患者的生存年限可超过5年。此外,胰腺癌细胞对细胞毒性细胞并不敏感且治疗效果不佳,因此,胰腺癌患者的存活率极低。因此,需要尽早研究出新的有效策略以提高胰腺癌患者的生存率和生存质量。

在一篇既往研究中,俄亥俄州立大学药物化学科Chenglong Li教授及其同事使用计算机系统和细胞试验证实,Bazedoxifene可作为一种IL-6抑制剂。

IL-6是一种细胞因子,它对于癌症在机体内的进展可扩散起着重要的作用。血清中IL-6水平较高则胰腺癌患者预后不佳,生存时间较短;因此,IL-6被认为是治疗胰腺癌的可行方案。

Bazedoxifene是第三代选择性雌激素受体调节剂,于2013年获得FDA批准可用于预防并治疗绝经后妇女出现的骨质疏松症。 

在当前的研究中,研究者们进一步探讨这种药物如何通过抑制IL-6信号通路而抑制抑制胰腺癌细胞的生长和繁殖。“Bazedoxifene已经被FDA批准可作为安全的新型IL-6抑制剂,当然还需要进行更多的临床试验以深入探究。”教授说道。

在当前的研究中,研究人员发现,人类胰腺癌细胞表达IL-6的水平对Bazedoxifene药物十分敏感,IL-6分子通过抑制癌细胞内的IL-6/STAT3信号通路以减少癌细胞的死亡数目。IL-6分子水平降低,则死亡的癌细胞数目增多,因此,胰腺癌患者的生存率可得以提高。

许多人到了中老年的时候个子会变“矮”,这其实是人体骨骼逐渐衰退的表现,最主要的“元凶”就是骨质疏松。作为中老年人最常见的骨骼疾病,由骨质疏松引起的骨折,轻则影响机体功能,重则致残甚至致死。10月20日是世界骨质疏松日,我们在认识和防治骨质疏松方面,存在哪些误区?有哪些办法可以自测是否为高危人群? 骨质疏松常见的8大误区: 1.喝骨头汤能防止骨质疏松 实验证明,同样一碗牛奶中的钙含量要远远高于

近期有研究称补钙并不能增加骨健康,那还要补钙么?这些研究的具体内容是什么呢?

因为钙是骨健康的基石,多年来,老年人被建议增加膳食钙的摄入量,或者被建议补充钙片。同时,由于没有维生素D人体不能吸收钙,因此维生素D通常作为补钙的搭档被推荐补充。近期有研究者对于这个经验性观点,进行了系统回顾。以探究补钙或者补充维生素D究竟能不能预防骨折,使我们的骨骼更健康,但是结果却出乎意料!这些研究,有2项发表在英国医学期刊(BMJ)上,还要一项发表在JAMA Intern Med上。1.BM
