Mitotic progression, arrest, exit or death relies on centromere structural integrity, rather than de novo transcription

eLife, 2018
Recent studies have challenged the prevailing dogma that transcription is repressed during mitosis. Transcription was also proposed to sustain a robust spindle assembly checkpoint (SAC) response.

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

The Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

Hepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

Preparation for mitosis requires gradual CDK1 activation

iScience
Summary: G2 phase is considered as a time in which cells prepare for the large structural changes in the following mitosis. Starting at completion of DNA replication, CDK1 and PLK1 kinase activities gradually increase throughout G2 phase until reaching ...

Replication Stress in Mammalian Cells and Its Consequences for Mitosis

Genes, 2015
The faithful transmission of genetic information to daughter cells is central to maintaining genomic stability and relies on the accurate and complete duplication of genetic material during each cell cycle.

Loss of Tripartite Motif–Containing Protein 21 and UVB‐Induced Systemic Inflammation by Regulating DNA‐Sensing Pathways

Arthritis &Rheumatology, EarlyView.
Objective Patients with systemic lupus erythematosus (SLE) experience photosensitivity, with exposure to UVB light driving lupus flares and triggering symptoms like joint pain, fatigue, and cutaneous lesions. Although the mechanism(s) linking UVB exposure to systemic effects are unclear, type I interferons (IFNs) are known to play a role.

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

Hepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Phosphorylated ERK5/BMK1 transiently accumulates within division spindles in mouse oocytes and preimplantation embryos

Folia Histochemica et Cytobiologica, 2011
MAP kinases of the ERK family play important roles in oocyte maturation, fertilization, and early embryo development. The role of the signaling pathway involving ERK5 MAP kinase during meiotic and mitotic M-phase of the cell cycle is not well known. Here,

Taking Down the Primary Cilium: Pathways for Disassembly in Differentiating Cells

BioEssays, EarlyView.
Primary cilia are developmentally essential subcellular signaling compartments. However, many differentiated cells lack primary cilia, and cilia disassembly in these tissue contexts has been largely overlooked. We highlight several pathways for primary cilia loss and examine how changes in ciliation states could contribute to diverse pathologies ...

Genome accessibility is widely preserved and locally modulated during mitosis

Genome Research, 2015
Mitosis entails global alterations to chromosome structure and nuclear architecture, concomitant with transient silencing of transcription. How cells transmit transcriptional states through mitosis remains incompletely understood.
