Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Phosphorylation of the Proapoptotic BH3-Only Protein Bid Primes Mitochondria for Apoptosis during Mitotic Arrest

Cell Reports, 2014
Mitosis is a moment of exquisite vulnerability for a metazoan cell. Failure to complete mitosis accurately can lead to aneuploidy and cancer initiation.

Chromosome Segregation Is Biased by Kinetochore Size [PDF]

, 2018
Chromosome missegregation during mitosis or meiosis is a hallmark of cancer and the main cause of prenatal death in humans. The gain or loss of specific chromosomes is thought to be random, with cell viability being essentially determined by selection ...

The Consequences of Chromosome Segregation Errors in Mitosis and Meiosis

Biology, 2017
Mistakes during cell division frequently generate changes in chromosome content, producing aneuploid or polyploid progeny cells. Polyploid cells may then undergo abnormal division to generate aneuploid cells.

Therapeutic strategies for MMAE‐resistant bladder cancer through DPP4 inhibition

Molecular Oncology, EarlyView.
We established monomethyl auristatin E (MMAE)‐resistant bladder cancer (BC) cell lines by exposure to progressively increasing concentrations of MMAE in vitro. RNA sequencing showed DPP4 expression was increased in MMAE‐resistant BC cells. Both si‐DPP4 and the DPP4 inhibitor sitagliptin suppressed the viability of MMAE‐resistant BC cells.

A PKD-MFF signaling axis couples mitochondrial fission to mitotic progression

Cell Reports, 2021
Summary: Mitochondria are highly dynamic organelles subjected to fission and fusion events. During mitosis, mitochondrial fission ensures equal distribution of mitochondria to daughter cells. If and how this process can actively drive mitotic progression

Epithelial tricellular junctions act as interphase cell shape sensors to orient mitosis

Nature, 2016
The orientation of cell division along the long axis of the interphase cell—the century-old Hertwig’s rule—has profound roles in tissue proliferation, morphogenesis, architecture and mechanics.

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

FEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

The effect of salubrinal on the endoplasmic reticulum stress pathway in heat‐stressed spermatogonial cells in vitro

FEBS Open Bio, EarlyView.
This study investigates the protective role of salubrinal against heat‐induced endoplasmic reticulum (ER) stress in mouse spermatogenic cells (GC1 and GC2). By modulating the ER stress pathway, salubrinal alleviates cellular stress and supports spermatogenic cell survival, suggesting its potential as a therapeutic candidate for heat‐related infertility.

Emerging Roles for Transcription Factors During Mitosis

Cells
The genome is dynamically reorganized, partitioned, and divided during mitosis. Despite their role in organizing interphase chromatin, transcription factors were largely believed to be mitotic spectators evicted from chromatin during mitosis, only able ...
