Effect of melanocyte stimulating hormone on human cultured choroidal melanocytes, uveal melanoma cells, and retinal epithelial cells.
PURPOSE To establish methodology for the culture of human choroidal melanocytes to compare their responsiveness to melanocyte stimulating hormone (MSH) with that of their transformed melanoma counterparts and with that of the retinal epithelial cell. METHODS Choroidal melanocytes from the choroid of eyes enucleated for the presence of malignant melanoma were cultured in MCDB 153 medium supple...
متن کاملDesacetyl-α-melanocyte stimulating hormone and α-melanocyte stimulating hormone are required to regulate energy balance
OBJECTIVE Regulation of energy balance depends on pro-opiomelanocortin (POMC)-derived peptides and melanocortin-4 receptor (MC4R). Alpha-melanocyte stimulating hormone (α-MSH) is the predicted natural POMC-derived peptide that regulates energy balance. Desacetyl-α-MSH, the precursor for α-MSH, is present in brain and blood. Desacetyl-α-MSH is considered to be unimportant for regulating energy b...
متن کاملOleoylethanolamide inhibits α-melanocyte stimulating hormone-stimulated melanogenesis via ERK, Akt and CREB signaling pathways in B16 melanoma cells
The present study aimed to examine the potential inhibitory activity of oleoylethanolamide (OEA) on α-melanocyte stimulating hormone (α-MSH)-stimulated melanogenesis and the molecular mechanism(s) involved in the process in B16 mouse melanoma cells. Our data demonstrated that OEA markedly inhibited melanin synthesis and tyrosinase activity in α-MSH-stimulated B16 cells. In addition, the express...
متن کاملResveratrol Inhibits Alpha-Melanocyte-Stimulating Hormone Signaling, Viability, and Invasiveness in Melanoma Cells
Melanoma is a malignancy with high potential to invasion and treatment resistance. The α -melanocyte-stimulating hormone ( α -MSH) signal transduction involving Wnt/ β -catenin, c-Kit, and microphthalmia-associated transcription factor (MITF), a known pathway to produce melanin, has been demonstrated as one of cancer stem cell characteristics. This study was aimed to examine the effect of resve...
متن کاملHyperglycemia- Induced NF-κB Activation Increases microRNA-146a Expression in Human Umbilical Vein Endothelial Cells
Background & objectives: Nuclear Factor kappa B (NF-κB), a master switch transcription factor, plays a critical role in the progression and development of hyperglycemia-induced microangiopathy. Hyperglycemia activates NF-κB, and subsequently increases pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β leading to development of inflammation. Some new studies have revealed the involvement o...
