Differential Signaling Profiles of MC4R Mutations with Three Different Ligands [PDF]

open access: yes, 2020
The melanocortin 4 receptor (MC4R) is a key player in hypothalamic weight regulation and energy expenditure as part of the leptin-melanocortin pathway. Mutations in this G protein coupled receptor (GPCR) are the most common cause for monogenetic obesity,

Transcriptomic diversification of granulosa cells during follicular development between White Leghorn and Silky Fowl hens

open access: yesFrontiers in Genetics, 2022
Egg production rate in chicken is related to the continuity of follicle development. In this study, we found that the numbers of white prehierarchical, dominant, and yellow preovulatory follicles in the high-yielding layer breed, White Leghorn (WL), were

Plasticity of differentiated cells in wound repair and tumorigenesis, Part II: Skin and intestine [PDF]

open access: yes, 2018
Recent studies have identified and begun to characterize the roles of regenerative cellular plasticity in many organs. In Part I of our two-part Review, we discussed how cells reprogram following injury to the stomach and pancreas.

Pigmented intramucosal nevus of gingiva with a special insight on its pathophysiology: Report of a rare entity

open access: yesJournal of Dr. NTR University of Health Sciences, 2017
Oral melanotic nevi can be characterized as developmental malformations or melanocytic tumors. Nevi are benign in nature originating from proliferating malfunctioning melanoblasts of the neural crest cells either in the epithelium or in connective tissue.

Melanocytic Nevus of the Colon [PDF]

open access: yesCase Reports in Gastroenterology, 2019
Here, we report a very rare case of melanocytic nevus of the colon. A 54-year-old woman with an unremarkable medical history visited our hospital for screening colonoscopy. Colonoscopy revealed a pigmented flat lesion in the ascending colon. Histological evaluation of a biopsy specimen revealed proliferation of pigmented cells in the lamina muscularis ...

Mohs micrographic surgery for melanoma: A convincing treatment modality

open access: yesIndian Journal of Dermatology, 2022
Mohs micrographic surgery (MMS) is the gold standard for treating keratinocyte carcinomas in specific locations or due to other tumor-specific factors, given its comprehensive margin assessment, tissue sparing, and high cure rate.

Modulation of social behavior by the agouti pigmentation gene [PDF]

open access: yes, 2014
Agouti is a secreted neuropeptide that acts as an endogenous antagonist of melanocortin receptors. Mice and rats lacking agouti (called non-agouti) have dark fur due to a disinhibition of melanocortin signaling and pigment deposition in the hair follicle.

Pituitary Adenylate Cyclase Activating Polypeptide Has Inhibitory Effects on Melanoma Cell Proliferation and Migration In Vitro

open access: yesFrontiers in Oncology, 2021
Pituitary adenylate cyclase activating polypeptide (PACAP) is an endogenous neuropeptide which is distributed throughout the body. PACAP influences development of various tissues and exerts protective function during cellular stress and in some tumour ...

p63 is an alternative p53 repressor in melanoma that confers chemoresistance and a poor prognosis. [PDF]

open access: yes, 2013
The role of apoptosis in melanoma pathogenesis and chemoresistance is poorly characterized. Mutations in TP53 occur infrequently, yet the TP53 apoptotic pathway is often abrogated.
