MiR-217 inhibition relieves oxidative stress-induced melanocyte damage by targeting sirtuin 1

Biotechnology & Biotechnological Equipment, 2020
Vitiligo is caused by the disappearance of melanocyte function in the skin, but the mechanism has not been fully elucidated. This study aimed to investigate the expression and role of miR-217 in dysfunctional human primary melanocytes caused by oxidative

PAIR: Reconstructing Single‐Cell Open‐Chromatin Landscapes for Transcription Factor Regulome Mapping

Advanced Science, EarlyView.
scATAC‐seq analysis is often constrained by limited sequencing depth, extreme sparsity, and pervasive technical missingness. PAIR is a probabilistic framework that restores scATAC‐seq accessibility profiles by directly modeling the native cell–peak bipartite structure of chromatin accessibility.

MicroRNA-206 Regulation of Skin Pigmentation in Koi Carp (Cyprinus carpio L.)

Frontiers in Genetics, 2020
MicroRNAs (miRNAs) are ∼22 nucleotide non-coding RNA molecules that act as crucial roles in plenty of biological processes. However, the molecular and cellular mechanisms of miRNAs to regulate skin color differentiation and pigmentation in fish have not ...

Single-Cell Transcriptomes Reveal a Complex Cellular Landscape in the Middle Ear and Differential Capacities for Acute Response to Infection. [PDF]

, 2020
Single-cell transcriptomics was used to profile cells of the normal murine middle ear. Clustering analysis of 6770 transcriptomes identified 17 cell clusters corresponding to distinct cell types: five epithelial, three stromal, three lymphocyte, two ...

Composition‐Aware Cross‐Sectional Integration for Spatial Transcriptomics

Advanced Intelligent Discovery, EarlyView.
Multi‐section spatial transcriptomics demands coherent cell‐type deconvolution, domain detection, and batch correction, yet existing pipelines treat these tasks separately. FUSION unifies them within a composition‐aware latent framework, modeling reads as cell‐type–specific topics and clustering in embedding space.

Transplantable melanomas in hamsters and gerbils as models for human melanoma : sensitization in melanoma radiotherapy : from animal models to clinical trials [PDF]

, 2018
The focus of the present review is to investigate the role of melanin in the radioprotection of melanoma and attempts to sensitize tumors to radiation by inhibiting melanogenesis. Early studies showed radical scavenging, oxygen consumption and adsorption

Atypical Clinical Course of Griscelli Syndrome Type 2 With Primarily Neurologic Presentation and Adult‐Onset in a 46‐Year‐Old Male

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Griscelli Syndrome Type 2 (GS2) is a rare autosomal recessive disorder caused by pathogenic mutations in the RAB27A gene. Typically, it is characterized by cutaneous hypopigmentation, immunodeficiency, with or without neurological abnormalities secondary to hemophagocytic lymphohistiocytosis (HLH). Without treatment, GS2 often results in fatal

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,
