Co-Treatment with Cranberry and Vitamin-C Mitigates Reproductive Toxicities Induced by Phenobarbital in Male Rats.

Background/aims: Phenobarbital (PB), commonly used for epilepsy management, is associated with testicular dysfunction after prolonged use. This study aimed to evaluate the ameliorative effects of cranberry (CB) and vitamin C (Vit-C) on PB-induced reproductive toxicity in rats.

Methods: Forty male Wistar rats were divided into five groups.

Epigenetic silencing of ZIC4 unveils a potential tumor suppressor role in pediatric choroid plexus carcinoma.

Zic family member ZIC4 is a transcription factor that has been shown to be silenced in several cancers. However, understanding the regulation and function of ZIC4 in pediatric choroid plexus tumors (CPTs) remained limited. This study employed data mining and bioinformatics analysis to investigate the DNA methylation status of ZIC4 in CPTs and its correlation with patient survival.

Biochemical Characterisation and Antitumour Effect of Parotoid Gland Secretions of the Egyptian Toad ().

This study aims to determine the biochemical compositions and the antitumour effect of the parotoid gland secretions (PGS) of the Egyptian toad (). The total protein, lipid, carbohydrate contents, total antioxidant capacity (TAC), the median inhibitory concentration (IC) of 2,2-diphenyl-1-picrylhydrazyl (DPPH), sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) profile, amino acid analysis, gas chromatography-mass spectrometry (GC-MS) analysis and minerals were determined in PGS. The antitumour effect of PGS against human hepatocellular carcinoma (HepG-2), breast adenocarcinoma (MCF-7) and normal lung fibroblast (WI-38) cell lines were determined.

LC3A-mediated autophagy elicits PERK-eIF2α-ATF4 axis activation and mitochondrial dysfunction: Exposing vulnerability in aggresome-positive cancer cells.

The unfolded protein response pathways (UPR), autophagy, and compartmentalization of misfolded proteins into inclusion bodies are critical components of the protein quality control network. Among inclusion bodies, aggresomes are particularly intriguing due to their association with cellular survival, drug resistance, and aggresive cancer behavior. Aggresomes are molecular condensates formed when collapsed vimentin cages encircle misfolded proteins before final removal by autophagy.
