Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

Acta Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...

Genotype‐Informed Whole‐Animal Kinome Screening Reveals Shared Kinase Vulnerabilities Across Driver Contexts in PDAC

Cancer Science, EarlyView.
Overview of experimental workflow and key findings. Clinically prevalent 2‐hit and 3‐hit PDAC genotypes were first modeled in Drosophila to enable kinome‐wide genetic screening. Candidate therapeutic targets were prioritized using human tumor expression data and pathway enrichment analyses.

A Noncanonical Protein Degradation Pathway That Regulates Germ Cell Maintenance

Cell Proliferation, EarlyView.
SENP8 regulates a non‐canonical NEDD8‐dependent pathway to stabilize STAT1, promote CCL2/CCL5 transcription, and maintain germ cell proliferation and migration.

Functional and transcriptomic analyses in Neurospora crassa reveal a crucial role for the N‐glycoprotein deglycosylation process in fungal homeostasis

The FEBS Journal, EarlyView.
In Neurospora crassa, a cytosolic GH18 endo‐β‐n‐acetylglucosaminidase (ENGase) functions as an active deglycosylating enzyme. Deletion of this severely alters tolerance to multiple stress conditions and causes extensive transcriptomic reprogramming, including upregulation of a GH20 exo‐β‐n‐acetylhexosaminidase under ER stress, indicating that N. crassa

The trimeric Shu complex in C. elegans is an ATPase that remodels RAD51 filaments in the homologous recombination‐associated DNA damage response

The FEBS Journal, EarlyView.
The C. elegans Shu complex (RFS‐1/RIP‐1/SWS‐1) is a DNA‐dependent ATPase that regulates RAD‐51 filaments during homologous recombination. The trimer preferentially binds 5′‐exposed DNA, remodels RAD‐51 filaments via ATP hydrolysis, and stabilizes filaments through ATP binding.

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.
