Backgrounds: Vitamin D regulates muscle function by binding to vitamin D receptors (VDR) via genomic signaling pathways. The biologically active form of vitamin D (1,25- (OH)D) affects muscles by modulation of gene transcription and protein kinase signaling pathways that support proliferation and muscle growth. Aging will result in the interaction of vitamin D and VDR, affecting the regulat…
Background: Malnutrition in nasopharyngeal carcinoma (NPC) patients is caused by various factors such as tumor localization, metabolic derangement, and side effects of therapy. Poor nutritional status in cancer patients is associated with serious clinical consequences such as poor quality of life, higher treatment toxicity, and poor prognosis. The purpose of this study was to determine the e…
