Cell cycle regulation of a Xenopus Wee1-like kinase [PDF]

, 1995
Using a polymerase chain reaction-based strategy, we have isolated a gene encoding a Wee1-like kinase from Xenopus eggs. The recombinant Xenopus Wee1 protein efficiently phosphorylates Cdc2 exclusively on Tyr- 15 in a cyclin-dependent manner.

Identification of Inhibitors of the Leishmania cdc2‐Related Protein Kinase CRK3 [PDF]

ChemMedChem, 2011
AbstractNew drugs are urgently needed for the treatment of tropical parasitic diseases such as leishmaniasis and human African trypanosomiasis (HAT). This work involved a high‐throughput screen of a focussed kinase set of ∼3400 compounds to identify potent and parasite‐selective inhibitors of an enzymatic Leishmania CRK3–cyclin 6 complex.

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Tau protein kinase II has a similar characteristic to cdc2 kinase for phosphorylating neurofilament proteins

Journal of Biological Chemistry, 1993
Tau protein kinase II purified from a bovine brain tau protein fraction (Ishiguro, K., Takamatsu, M., Tomizawa, K., Omori, A., Takahashi, M., Arioka, M., Uchida, T., and Imahori, K. (1992) J. Biol. Chem. 267, 10897-10901) was shown to have a similar substrate specificity to cdc2 kinase in that both phosphorylate neurofilament (NF) proteins. Tau protein

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

Phosphorylation of numatrin and other nuclear proteins by cdc2 containing CTD kinase cdc2/p58

Journal of Biological Chemistry, 1991
Numatrin is a nuclear matrix phosphoprotein whose synthesis and abundance were shown to be regulated during the cell cycle in mitogen-stimulated lymphocytes (Feuerstein, N., and Mond, J. (1987) J. Biol. Chem. 262, 11389-11397). We examined the effect of (a) CTD-kinase, which contains the cdc2 catalytic component (p34) in a complex with a p58 subunit ...

IL4I1⁺ Macrophages and TDO2⁺ Myofibroblasts Drive AhR‐Mediated Immunosuppression and Ferroptosis Resistance in Solid Predominant Lung Adenocarcinoma

Advanced Science, EarlyView.
Solid predominant lung adenocarcinoma exhibits an immune‐excluded, ferroptosis‐resistant niche enriched with IL4I1⁺ TAMs and TDO2⁺ myCAFs. Spatial and multi‐omics analyses reveal AhR‐driven crosstalk that promotes T cell exhaustion and therapy resistance. Blocking AhR with CH‐223191 restores ferroptosis sensitivity, and its combination with ferroptosis

Nicotine-Induced Apoptosis in Human Renal Proximal Tubular Epithelial Cells. [PDF]

PLoS ONE, 2016
Nicotine is, to a large extent, responsible for smoking-mediated renal dysfunction. This study investigated nicotine's effects on renal tubular epithelial cell apoptosis in vitro and it explored the mechanisms underlying its effects.Human proximal ...
