Mitotic Reorganization of the Intermediate Filament Protein Nestin Involves Phosphorylation by cdc2 Kinase [PDF]
The intermediate filament protein nestin is expressed during early stages of development in the central nervous system and in muscle tissues. Nestin expression is associated with morphologically dynamic cells, such as dividing and migrating cells. However, little is known about regulation of nestin during these cellular processes. We have characterized

TP53‐Mutated Acute Myeloid Leukemia: Unanswered Questions
ABSTRACT TP53‐mutated acute myeloid leukemia (AML) remains one of the most treatment‐resistant hematologic malignancies, with poor overall survival despite advancements in therapeutic strategies. The loss of functional p53 compromises DNA repair, apoptosis, and genomic stability, rendering both conventional and novel therapies largely ineffective. This

CLK2 blockade modulates alternative splicing compromising MYC‐driven breast tumors
MYC oncogene overexpression/amplification is common in multiple human cancers, in which it regulates proliferation, apoptosis and cell metabolism, among other processes, and its expression associates with poor prognosis.

Comparing Theories for the Maintenance of Late LTP and Long-Term Memory: Computational Analysis of the Roles of Kinase Feedback Pathways and Synaptic Reactivation [PDF]
How can memories be maintained from days to a lifetime, given turnover of proteins that underlie expression of long-term synaptic potentiation (LTP)? One likely solution relies on synaptic positive feedback loops, prominently including persistent activation of CaM kinase II (CaMKII) and self-activated synthesis of protein kinase M zeta (PKM).

Skeletal muscle cells lacking the retinoblastoma protein display defects in muscle gene expression and accumulate in S and G2 phases of the cell cycle. [PDF]
Viral oncoproteins that inactivate the retinoblastoma tumor suppressor protein (pRb) family both block skeletal muscle differentiation and promote cell cycle progression.

Proteasome-mediated proteolysis of SRSF5 splicing factor intriguingly co-occurs with SRSF5 mRNA upregulation during late erythroid differentiation. [PDF]
SR proteins exhibit diverse functions ranging from their role in constitutive and alternative splicing, to virtually all aspects of mRNA metabolism. These findings have attracted growing interest in deciphering the regulatory mechanisms that control the ...

p34 kinase, the product of the CDC2 gene, is a cell-cycle regulated protein kinase that is most active during mitosis. In HeLa cells, p34 kinase has previously been shown to exist in both a low- and a high-molecular-mass form, the latter of which is only

Single‐Cell Atlas Reveals Tumorigenic Profiles and Immune Dynamics of Adrenal Incidentalomas
Single‐cell RNA sequencing reveals cellular heterogeneity in adrenal incidentalomas, identifying distinct tumor cell populations. Clusterin is recognized as a biomarker for adrenocortical tumors, correlating with established markers. MYCN‐positive clusters in pheochromocytomas indicated poorer survival.
