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.

Phosphatidylinositol Inhibits Vascular Endothelial Growth Factor-A–Induced Migration of Human Umbilical Vein Endothelial Cells

Journal of Pharmacological Sciences, 2008
Phosphatidylinositol (PI), a phospholipid in component of cell membranes, is widely distributed in animals, plants, and microorganisms. Here, we examined in vitro whether PI inhibits the angiogenesis induced by vascular endothelial growth factor-A (VEGF ...

Phosphorylation and Activation of Heart 6-Phosphofructo-2-kinase by Protein Kinase B and Other Protein Kinases of the Insulin Signaling Cascades*

Journal of Biological Chemistry, 1997
To understand the insulin-induced activation of 6-phosphofructo-2-kinase (PFK-2) of the bifunctional enzyme PFK-2/fructose-2,6-bisphosphatase in heart, the effect of phosphorylation by protein kinases of the insulin signaling pathways on PFK-2 activity ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

PSMA redirects MAPK to PI3K-AKT signaling to promote prostate cancer progression

Molecular & Cellular Oncology, 2017
Increased Prostate Specific Membrane Antigen expression promotes tumor progression in prostate epithelium by dysregulating the β1-integrin/type I insulin-like growth factor receptor axis, resulting in a shift in signaling from the less aggressive mitogen-

INHIBITION OF TROPOMYOSIN-RECEPTOR-KINASE B AND PHOSPHOINOSITIDE 3-KINASE/PROTEIN KINASE B SIGNALING CASCADE

INDONESIAN JOURNAL OF PHARMACY, 2014
La triméthyltine (TMT, 2.4mg/kg, i.p) peut déclencher des lésions neuronales en inhibant le récepteur de la tropomyosine kinase B (récepteur TrkB), suivi de la phosphoinositide 3-kinase (PI3K)/protéine kinase B ou de la cascade de signalisation Akt. We examined hippocampal changes in TrkA/B phosphorylation on Tyr490/Tyr516 of TMT-treated mice in a time-

FKBP51 regulation of AKT/protein kinase B phosphorylation [PDF]

Current Opinion in Pharmacology, 2011
FK506 binding protein 51 (FKBP51, also called FKBP5) belongs to a family of immunophilins, FK506 binding proteins (FKBPs). FKBP family members are targets for drugs such as rapamycin. Although FKBP51 shares characteristics with other FKBPs, it also has unique features, especially the role in its regulation of important signaling pathways such as the ...

Protein kinase B (PKB/Akt) activity is elevated in glioblastoma cells due to mutation of the tumor suppressor PTEN/MMAC.

Current Biology, 1998
Glioblastomas are highly malignant tumors of the central nervous system that are resistant to radiation and chemotherapy [1]. We explored the role of the phosphatidylinositol (PI) 3-kinase signal transduction pathway in glioblastomas, as this pathway has

Effective therapeutic targeting of CTNNB1‐mutant hepatoblastoma with WNTinib

Molecular Oncology, EarlyView.
WNTinib, a Wnt/CTNNB1 inhibitor, was tested in hepatoblastoma (HB) experimental models. It delayed tumor growth and improved survival in CTNNB1‐mutant in vivo models. In organoids, WNTinib outperformed cisplatin and showed enhanced efficacy in combination therapy, supporting its potential as a targeted treatment for CTNNB1‐mutated HB.
