The cell cycle–apoptosis connection revisited in the adult brain [PDF]
Adult neurogenesis is studied in vivo using thymidine analogues such as bromodeoxyuridine (BrdU) to label DNA synthesis during the S phase of the cell cycle.

Rescue of Cyclin D1 Deficiency by Knockin Cyclin E [PDF]
D-type cyclins and cyclin E represent two very distinct classes of mammalian G1 cyclins. We have generated a mouse strain in which the coding sequences of the cyclin D1 gene (Ccnd1) have been deleted and replaced by those of human cyclin E (CCNE). In the tissues and cells of these mice, the expression pattern of human cyclin E faithfully reproduces ...

The biomimetic nanoplatform IMNP (ETS1 pDNA/PBAE@ITP‐MM) undergoes targeted disassembly at inflammatory vascular sites to release the ETS1 plasmid (pETS1). This release initiates a cascade of effects that inhibit pathogenic pathways and support immune homeostasis. (Abbreviations: EndMT, endothelial‐to‐mesenchymal transition; EC, endothelial cell; TC, T

The p53-MDM2 network: from oscillations to apoptosis [PDF]
The p53 protein is well-known for its tumour suppressor function. The p53-MDM2 negative feedback loop constitutes the core module of a network of regulatory interactions activated under cellular stress.

Complex oscillations in the activation and inactivation of cyclin-dependent kinase complexes propel mammalian cells through the cycle. A recent spate of studies seems to indicate that many, if not most, of these seemingly essential molecules may, in some senses, be dispensable.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Cdc13 (cyclin B) is degraded by autophagy under sulfur depletion in fission yeast
Cyclins are degraded by the anaphase-promoting complex/cyclosome (APC/C)-mediated proteasome in normal mitosis. We showed that Cdc13 (cyclin B) is also degraded by macroautophagy/autophagy in sulfur-deficient fission yeast.

Microbiota and bile acid profiles in retinoic acid-primed mice that exhibit accelerated liver regeneration. [PDF]
Background & aimsAll-trans Retinoic acid (RA) regulates hepatic lipid and bile acid homeostasis. Similar to bile acid (BA), RA accelerates partial hepatectomy (PHx)-induced liver regeneration.

Bufalin Inhibits the PI3K/AKT Pathway by Targeting GTF3C4 to Impede Breast Cancer Progression
Mechanisms of Bufalin‐Mediated Intervention in Breast Cancer. ABSTRACT Breast cancer incidence is rising globally, presenting challenges such as treatment side effects and drug resistance. Bufalin is a bufadienolides compound with potential anti‐cancer effects. This study shows that bufalin inhibits malignant proliferation of MDA‐MB‐231 and MCF‐7 cells

Analysis of the mitotic exit control system using locked levels of stable mitotic cyclin
Cyclin‐dependent kinase (Cdk) both promotes mitotic entry (spindle assembly and anaphase) and inhibits mitotic exit (spindle disassembly and cytokinesis), leading to an elegant quantitative hypothesis that a single cyclin oscillation can function as a ...
