Striated muscle tissue yahoo dating


The importance of vitamin D on muscle mass and bone health has been much debated. Vitamin D has beneficial effect on sarcopenia and frailty especially in patients with kidney disease, cancers, chronic obstructive pulmonary disease and elderly people [].

Serum concentrations of vitamin D are measured in the form of hydroxyvitamin D 25 OHDbut may suffer "Striated muscle tissue yahoo dating" with advancing age, sun exposure, ethnicity, body mass index and calcium and phosphorus metabolism [4].

One of the consequences, probably due to intramuscular lipid accumulation, is insulin resistance [7]. In cancer, in vivo and in vitro studies that administrated vitamin D analogues have demonstrated anti-proliferative effects in cancer cells, as well as reduction in tumor cells invasiveness and migration [8,9].

Regarding muscle mass and strength, it is known that vitamin D participates in the modulation of muscle growth and frailty Figure 1.

Indeed, studies have found that the skeletal muscle cells exhibit the vitamin D receptor, which is able to generate molecular and physiological effects on myocytes. With respect to mechanisms of action, it is observed that after vitamin D intake an increase in Insulin Growth Factor expression IGF occurs; alongside, an increase in Striated muscle tissue yahoo dating metabolism through calcium-binding protein calbindin-D28k and an increase in calcium influx in myocytes by activation of MAP kinase and phospholipase C, promoting muscle contraction and increased proliferation and differentiation of type 2 muscle fibers is also observed [].

Several studies, have shown that supplementation with vitamin D3 analogs improves sarcopenia, frailty, bone health and gait speed. Supplementation at a dose of IU per day appears to be effective in increasing the muscle mass and strength and attenuate the falls number in the Striated muscle tissue yahoo dating subjects [13,14] Figure 1.

However, high-dose of supplementation with vitamin D IU plus calcifediol or IU per day is associated with higher 25OHD concentrations and more falls in the elderly was also found [15]. Even though the control of 25OHD concentrations is a good strategy to monitor vitamin D deficiency, excessive supplementation is not beneficial to human health. Furthermore, future nutritional and environmental strategies, such as the control and promotion of vitamin D-rich food sources and controlled sun exposure should be taken to prevent the appearance of more fragile and sarcopenic elderly.
