[摘要] 维生素D是一类甾体化合物,具有多种生物学功能,包括促进小肠对钙和磷的吸收、构建和维持骨质的硬度等。近年的研究发现,维生素D能抑制肿瘤细胞增殖和诱导分化、凋亡以及对某些癌症的发生有预防作用。因此,测定血清维生素D浓度可能对肿瘤的发生和发展判断有帮助。然而,除了乳腺癌外,血清维生素D与肿瘤的关系仍然存在...
"This study was interesting because it looked at sun exposure, cloud cover, as well as vitamin D levels in over 170 countries. And there's a clear association with less sun, lower vitamin D levels and higher incidences of certain cancers, particularly colon cancer and breast cancer." Norton...
Vitamin D DeficiencyPrognosisAgedMiddle AgedUnited StatesEuropeFemalePeople with very low levels of vitamin D seem to have a higher risk of death from all causes, a study in The BMJ has found1—including cardiovascular disease, and cancer if they have a history of cancer. The group of ...
"Activating the vitamin D receptor can trigger the anti-inflammatory function of genes to help cells survive under stressed conditions," said Michael Downes, a Salk senior staff scientist and co-corresponding author. "In this study, we looked at diabetes, but because this is an important receptor...
Background Vitamin D has been hypothesized to reduce cancer mortality through its effects on incidence and/or survival. Epidemiologic studies of the association of 25-hydroxyvitamin D [25(OH)D] and the risk of cancer, however, have been largely limited to incident cancers at a few sites. Metho...
Vitamin D:抗癌新星? 引言:Vitamin D(VD)对人体健康的影响颇为广泛。骨化三醇作为生物活性最高的一种VD形式,在除了保持人体钙平衡以外,其对抗恶性细胞增生和促恶性细胞分化的作用被研究者发现之后,VD作为抗癌防癌治疗的药物的可能性也倍受关注[1]。 1. VD的荷尔蒙作用...
Among the more than 25,000 participants in the VITAL study, 1,617 were diagnosed with invasive cancer over the next five years. This included a broad mix of cancers (breast, prostate, colorectal, lung and more). Of the almost 13,000 participants who received vitamin D, 226 were diagnosed...
"The more we know about vitamin D, the more we understand that it may play a key role in cancer prevention and prognosis," Kushi said. "This study adds to the evidence that vitamin D is an important nutrient."
Vitamin D deficiency could be the reason African American men experience more aggressive prostate cancer at a younger age compared with European American men, new research from Cedars-Sinai Cancer suggests. The multi-institutional study, published in Cancer Research Communications, a journal of the Ame...
