Early weaning management followed by energy supplementation can lead to metabolic alterations in the calf that exert long-term effects on the animal's health and performance. It is believed that the main molecular basis underlying these metabolic adaptations are epigenetic mechanisms that regulate, activate, or silence genes at different stages of development and/or in response to different environmental stimuli. However, little is known about postnatal metabolic programming in .

Background: Castration is a common practice in beef cattle production systems to manage breeding and enhance meat quality by promoting intramuscular fat (IMF) deposition, known as marbling. However, the molecular mechanisms that are influenced by castration in beef cattle are poorly understood. The aim of this study was to identify differentially expressed genes (DEGs) and metabolic pathways that regulate IMF deposition in crossbred cattle by RNA sequencing (RNA-Seq) of skeletal muscle tissue.

Introduction: Recent advancements in glioma treatment are largely driven by the identification of genetic alterations, which enhance diagnostic precision and prognostic assessments, and unveil potential therapeutic targets. TERT promoter mutations, in particular, are associated with a poorer prognosis and aggressive clinical behavior.
Methodology: This study explores the genetic interplay between TERT and other genes (ntrk, pdl1, alk, idh, p53, egfr, her2) in brain tumors through an integrative literature review.
Background/aims: Colorectal cancer prevention relies on surveillance colonoscopy, with the adenoma detection rate as a key factor in examination quality. Linked color imaging (LCI) enhances lesion contrast and improves the examination performance. This systematic review and meta-analysis aimed to evaluate the effect of LCI on adenoma detection rate in adults who underwent colonoscopy.

Our objective was to contribute to an understanding of the role of these genes inbacterial virulence for mice (Mus musculus) using an S.
