Identification of Yeast Protein Sequences With Similarity to the ESCRT‐III Protein Snf7

open access: yesYeast, EarlyView.
ABSTRACT Endosomal sorting complex required for transport (ESCRT‐III) is a membrane remodeling complex involved in a large number of cellular processes. It appears to perform an essential function in eukaryotes, since to date no eukaryotic organism completely devoid of ESCRT‐III has been found.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

open access: yesInsect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

open access: yesAndrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

Male Mice Heterozygous for Protamine 1 and Protamine 2 Are Infertile, Displaying Sperm Damage and Retention of Protamine 2 Precursors, Transition Proteins, and Histones

open access: yesAndrology, EarlyView.
ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Decreased Expression by a Chemically Modified siRNA to PTBP1 Seriously Affects Warburg Effect in Colorectal Cancer Cells

open access: yesCancer Science, EarlyView.
Chemically modified siR‐PTBP1 disrupts the Warburg effect by reprogramming pyruvate kinase splicing from PKM2 to PKM1. This metabolic shift activates the TCA cycle, increases ATP production, and excessive ROS generation, and ultimately induces apoptotic cell death in colorectal cancer cells.

Genetic Engineering of Tumor‐Infiltrating Lymphocytes (TIL) via a T‐Editor Platform to Enhance Anti‐Tumor Activity

open access: yesCancer Science, EarlyView.
A rapid and efficient CRISPR‐mediated gene editing platform for TIL engineering identified FAM84B as a novel potential target to enhance antitumor activity and pioneered the use of CBE to generate FAM84B loss‐of‐function TIL with enhanced antitumor activity.

Monocytes Derived From Human Pluripotent Stem Cells Engineered for Detection of Pyrogens

open access: yesCell Proliferation, EarlyView.
In summary, we have developed a monocyte‐based reporter system using hESC‐Mono for interrogating the NF‐κB signalling axis, a central pathway governing pyrogenic responses. Our platform enables rapid and dose‐dependent detection of both endotoxins (LPS) and non‐endotoxins (LTA and Zymosan).
