Herpes simplex virus type 1 R-loops are targets for APOBEC-mediated mutagenesis

Genome Biology
APOBEC3 enzymes are key effectors of antiviral immunity that introduce mutations into viral genomes. We show that viral R-loops serve as preferred substrates for APOBEC3-mediated mutagenesis during herpes simplex virus type 1 (HSV-1) infection.

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

One size does not fit all: An in vitro evaluation of the effects of bezafibrate and medroxyprogesterone acetate on human SH‐SY5Y and U‐87 MG cancer cells

FEBS Open Bio, EarlyView.
Drugs previously repurposed to target blood cancers reduced neuroblastoma and glioblastoma cell growth and viability. However, their levels of anticancer activity were different and their clinical application may be problematic due to side effects at effective doses.

Description of the Seminiferous Epithelium Cycle Stages in the Zebra Finch Taeniopygia guttata

Animals
Spermatogenesis in passerine birds remains poorly characterized. Previous studies focused on the steps of spermiogenesis, while a detailed staging of the seminiferous epithelium cycle is still lacking for this order.

Isolation and characterization of "Arabidopsis" mutants with altered homologous recombination levels : a new function for an INO80 SWI/SNF ATPase [PDF]

, 2006
Homologous recombination (HR) in eukaryotic organisms serves a dual role in providing genetic flexibility by creating novel sequence assortments upon meiosis and in maintaining genome integrity through DNA repair in somatic tissues.

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

HIV-1 transcription start sites usage and its impact on unspliced RNA functions in people living with HIV

mBio
HIV-1 unspliced RNA serves two distinct functions during viral replication: it is packaged into particles as the viral genome, and it is translated to generate Gag/Gag-Pol polyproteins required for virus assembly. Recent studies have demonstrated that in
