Insulin activation of Rheb , a mediator of mTOR / S 6 K / 4 E - BP signaling
Tumor suppressor genes evolved as negative effectors of mitogen and nutrient signaling pathways, such that mutations in these genes can lead to pathological states of growth. Tuberous sclerosis (TSC) is a potentially devastating disease associated with mutations in two tumor suppressor genes, TSC1 and 2, that function as a complex to suppress signaling in the mTOR/S6K/4E-BP pathway. However, th...
متن کاملToll-Like Receptor 4 Signaling is Involved in IgA-Stimulated Mesangial Cell Activation
PURPOSE Deposition of polymeric IgA1 in the kidney mesangium is the hallmark of IgA nephropathy, but the molecular mechanisms of IgA-mediated mesangial responses and inflammatory injuries remain poorly understood. We hypothesize that Toll-like receptor 4 (TLR4) is involved in IgA-induced mesangial cell activation. MATERIALS AND METHODS Mouse mesangial cells were stimulated with lipopolysaccha...
متن کاملActivation of oncogenic tyrosine kinase signaling promotes insulin receptor-mediated cone photoreceptor survival
In humans, daylight vision is primarily mediated by cone photoreceptors. These cells die in age-related retinal degenerations. Prolonging the life of cones for even one decade would have an enormous beneficial effect on usable vision in an aging population. Photoreceptors are postmitotic, but shed 10% of their outer segments daily, and must synthesize the membrane and protein equivalent of a pr...
متن کاملMelanocortin 4 receptor becomes an ACTH receptor by coexpression of melanocortin receptor accessory protein 2.
Melanocortin 2 receptor (MC2R) is the only canonical ACTH receptor. Its functional expression requires the presence of an accessory protein, known as melanocortin receptor 2 accessory protein 1 (MRAP1). The vertebrate genome exhibits a paralogue gene called MRAP2, which is duplicated in zebrafish (MRAP2a and MRAP2b), although its function remains unknown. In this paper, we demonstrate that MRAP...
متن کاملPodocyte Melanocortin 1 Receptor Mediated Signaling
Treatment of patients with nephrotic syndrome (NS) is currently unspecific and directed at ameliorating the symptoms rather than eliminating the cause. NS is actually a multitude of glomerular diseases characterized by poorly understood disease mechanisms and symptoms that include proteinuria, hypoalbuminemia and edema. Originally described in the 1950s, treatment of NS with adrenocorticotropic...
