Mouse Chd4-NURD is required for neonatal spermatogonia survival and normal gonad development

open access: yesEpigenetics & Chromatin, 2022
Testis development and sustained germ cell production in adults rely on the establishment and maintenance of spermatogonia stem cells and their proper differentiation into spermatocytes.

DNA damage triggers squamous metaplasia in human lung and mammary cells via mitotic checkpoints

open access: yesCell Death Discovery, 2023
Epithelial transdifferentiation is frequent in tissue hyperplasia and contributes to disease in various degrees. Squamous metaplasia (SQM) precedes epidermoid lung cancer, an aggressive and frequent malignancy, but it is rare in the epithelium of the ...

A stress-blinded Atf1 can fully assemble heterochromatin in a RNAi-independent minimal mat locus but impairs directionality of mat2/3 switching

open access: yesiScience, 2022
Summary: The MAP kinase Sty1 phosphorylates and activates the transcription factor Atf1 in response to several stress conditions, which then shifts from a transcriptional repressor to an activator.

miR-17 ~ 92 suppresses proliferation and invasion of cervical cancer cells by inhibiting cell cycle regulator Cdt2

open access: yesDiscover Oncology, 2023
Cervical cancer (CC) is the 4th most leading cause of death among women worldwide, and if diagnosed in late stages the treatment options are almost negligible. 99% of CC is caused by high-risk human papilloma viruses (HR-HPV). Upon integration into human

Targeting of Fzr/Cdh1 for timely activation of the APC/C at the centrosome during mitotic exit

open access: yesNature Communications, 2016
The activity of the anaphase-promoting complex/cyclosome (APC/C) needs to be regulated in time and space to perform different functions. Here the authors show that Spd2 localizes the APC/C activator Fzr at the centrosomes to promote optimal APC/C ...

Cortical Cyclin A controls spindle orientation during asymmetric cell divisions in Drosophila

open access: yesNature Communications, 2022
The Frizzled/Dishevelled planar cell polarity pathway is involved in mitotic spindle orientation, but how this is coordinated with the cell cycle is unclear.

miR-34a negatively regulates cell cycle factor Cdt2/DTL in HPV infected cervical cancer cells

open access: yesBMC Cancer, 2022
MicroRNAs have emerged as an important regulator of cell cycle and various other cellular processes. Aberration in microRNAs has been linked with development of several cancers and other diseases but still very little is known about the mechanism by ...

ATR Kinase Is a Crucial Player Mediating the DNA Damage Response in Trypanosoma brucei

open access: yesFrontiers in Cell and Developmental Biology, 2020
DNA double-strand breaks (DSBs) are among the most deleterious lesions that threaten genome integrity. To address DSBs, eukaryotic cells of model organisms have evolved a complex network of cellular pathways that are able to detect DNA damage, activate a

Cdc14 phosphatase counteracts Cdk-dependent Dna2 phosphorylation to inhibit resection during recombinational DNA repair

open access: yesNature Communications, 2023
Cyclin-dependent kinase (Cdk) stimulates resection of DNA double-strand breaks ends to generate single-stranded DNA (ssDNA) needed for recombinational DNA repair.

Conditional control of fluorescent protein degradation by an auxin-dependent nanobody

open access: yesNature Communications, 2018
Current approaches to conditionally deplete target proteins require site-specific genetic engineering or have poor temporal control. Here the authors overcome these limitations by combining the AID system with nanobodies to reversibly degrade GFP-tagged ...
