The contribution of the UV component of sunlight to the development of skin cancer is widely acknowledged, although the molecular mechanisms that are disrupted by UV radiation (UVR) resulting in the loss of normal growth controls of the epidermal stem cell keratinocytes and melanocytes is still poorly understood. Alpha-melanocyte stimulating hormone (alpha-MSH), acting via its receptor MC1, has...
PODOCYTES are the key target cell for injury in proteinuric kidney disorders such as focal segmental glomerulosclerosis (FSGS), minimal change disease, and membranous nephropathy. Sadly, advances in elucidating the molecular architectural details of the podocyte actin cytoskeleton, cell body, and intervening slit diaphragm have not yet translated into targeted therapeutic agents for clinical us...
The melanocortin-1 receptor (MC1R) gene has been investigated by many studies regarding the pigmentation variation in various species. In order to determine its allelic and genotypic distribution, we sequenced the goat MC1R gene from 78 individuals in ten populations (Gembrong, Senduro, Ettawa Grade, Boerawa, Boerka, Kosta, Samosir, Muara, Boer and Kacang). Direct sequencing m...
Black Forest horses are typically chestnut colored with flaxen mane and tail. However, as their coat color can get very dark, they are sometimes also indicated as silver, a color depending on a black base color. To analyse if the silver allele is present in the Black Forest horse population, we genotyped 250 horses of this breed for formerly reported coat color mutations within MC1R and SILV. A...
Finasteride is a well-known 5α-reductase inhibitor used for treatment of alopecia and prostate cancer. But the effect of finasteride in regulating melanogenesis is still unclear. In the present study the role of finasteride on melanogenesis was investigated. Finasteride decrease melanin level in melanocyte melan-a cells and B16F10 melanoma cells without inducing cytotoxicity. MC1R (melanocortin...
We describe a minisequencing protocol for screening DNA samples for the presence of 12 mutations in the human melanocortin 1 receptor gene (MC1R), eight of which are associated with the red hair phenotype. A minisequencing profile which shows homozygosity for one of these mutations or the presence of two different mutations would strongly indicate that the sample donor is red haired. The absenc...
دو نوع ملانین (فی ملانین، تولید کننده رنگ قرمز و یوملانین، تولید کننده رنگ سیاه) در ملانوسیت-های موجود در پوست پستانداران وجود دارد که نسبت آ ن ها توسط هورمون محرک ملانوسیت (msh) با تأثیر بر گیرنده ملانوکورتین (mc1r) تنظیم می شود، بنابراین جهش ها در گیرنده ملانوکورتین می تواند باعث تغییر رنگ شود. بر این اساس هدف از این پژوهش تعیین بیان ژن و تنوع ژنتیکی در گیرنده ملانوکورتین گوسفندی و ارتباط آن ...
BACKGROUND Skin ageing is said to be caused by multiple factors. The relationship with sun exposure is of particular interest because the detrimental cutaneous effects of the sun may be a strong motivator to sun protection. We report a study of skin ageing in participants of an epidemiological study of melanoma. OBJECTIVES To determine the predictors of periorbital cutaneous ageing and whethe...
PURPOSE Modular nanotransporters (MNTs) are a polyfunctional platform designed to achieve receptor-specific delivery of short-range therapeutics into the cell nucleus by receptor-mediated endocytosis, endosome escape, and targeted nuclear transport. This study evaluated the potential utility of the MNT platform in tandem with Auger electron emitting 111In for cancer therapy. METHODS Three MNT...
Looking young for one's age has been a desire since time immemorial. This desire is attributable to the belief that appearance reflects health and fecundity. Indeed, perceived age predicts survival [1] and associates with molecular markers of aging such as telomere length [2]. Understanding the underlying molecular biology of perceived age is vital for identifying new aging therapies among othe...
