BACKGROUND: Angiopoietin-like protein 8 (ANGPTL8) is considered to be metabolically multifunctional. One notable function still to be elucidated definitively is a betatrophic role in protecting and preserving pancreatic beta-cell function. There is, however, a paucity of data regarding the role of ANGPTL8 in the etiology of type 2 diabetes (T2D), but some findings of human research have suggested the potential for significant involvement. OBJECTIVE: To examine the frequency of T2D and impaired glucose tolerance (IGT) in Japanese subjects with the ANGPTL8 R59W variant...

Preterm birth (PTB) is featured by less than 37weeks of gestational age or fewer than 259days since the first day from the last menstrual period. Complications of PTB are the major cause of neonatal deaths, several factors are linked to PTB increased risk including immunological and genetics. Vitamin D plays an important role in immune response modulation and its action occurs through the vitamin D receptor (VDR), which recently has been described as overexpressed in human placenta during the pregnancy. Herein we assessed two single nucleotide polymorphisms (SNPs) FokI (rs2228570 A>G) and Cdx-2 (rs11568820 T>C), within VDR, using TaqMan fluorogenic probes, and differential susceptibility to SPTB...

In recent years, a vast amount of studies have centered on the role of vitamin D in the pathogenesis of certain types of cancers such as breast, colorectal and lung cancer. Increasing evidence suggests that vitamin D and its receptor play a crucial role in the development of gynecological cancers. In this review, we systematically analyzed the effect of vitamin D and the vitamin D receptor on endometrial, ovarian, cervical, vulvar and vaginal cancer. Our literature research shows that vitamin D levels and vitamin-D-related pathways affect the risk of gynecological cancers...
