CRISPR-Cas9 screening identified novel subtypes of cutaneous melanoma based on essential cancer genes.

Our primary objective was to identify genes critical for cutaneous melanoma (CM) and related typing, based on essential genes, to generate novel insights for clinical management and immunotherapy of patients with CM. We analyzed RNA sequencing (RNA-seq) data from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx), and sequencing data of 29 CM cell line from Cancer Cell Line Encyclopedia (CCLE) databases. Combined with DepMap database, 406 CM essential cancer genes were finally obtained.

Retinal pigment epithelium cell-derived exosomes: Possible relevance to CNV in wet-age related macular degeneration.

Exosomes are small vesicles that are released by almost every cell type and play a crucial role in many physiological and pathological processes associated with different diseases. Specifically, they promote angiogenesis in the pathogenesis of some diseases. According to previous research, the proteins of exosomes taken from the aqueous humor (AH) of patients with wet-age related macular degeneration (AMD) may function as a new diagnostic biomarker of AMD, suggesting that exosomes may play an important role in the occurrence and development of choroidal neovascularization (CNV).

Exogenous NAD(+) decreases oxidative stress and protects H2O2-treated RPE cells against necrotic death through the up-regulation of autophagy.

Increased oxidative stress, which can lead to the retinal pigment epithelium (RPE) cell death by inducing ATP depletion and DNA repair, is believed to be a prominent pathology in age-related macular degeneration (AMD). In the present study, we showed that and 0.1 mM nicotinamide adenine dinucleotide (NAD(+)) administration significantly blocked RPE cell death induced by 300 μM H2O2.
