ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

The STAT3 Transcription Factor Is a Target for the Myc and Riboblastoma Proteins on the Cdc25A Promoter [PDF]

Journal of Biological Chemistry, 2005
The STAT3 (signal transducer and activator of transcription) transcription factor functions as down-stream effector of growth factor signaling. Whereas STAT3 activation is transient in normal cells, constitutively activated forms of the transcription factor have been detected in several cancer cell lines and primary tumors. Through the up-regulation of

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

The Transcription Factor STAT3 Is Required for T Helper 2 Cell Development [PDF]

Immunity, 2011
Signal transducer and activator of transcription (STAT) family members direct the differentiation of T helper cells, with specific STAT proteins promoting distinct effector subsets. STAT6 is required for the development of T helper 2 (Th2) cells, whereas STAT3 promotes differentiation of Th17 and follicular helper T cell subsets.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

STAT3 precedes HIF1α transcriptional responses to oxygen and oxygen and glucose deprivation in human brain pericytes. [PDF]

PLoS ONE, 2018
Brain pericytes are important to maintain vascular integrity of the neurovascular unit under both physiological and ischemic conditions. Ischemic stroke is known to induce an inflammatory and hypoxic response due to the lack of oxygen and glucose in the ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Activation of Acute Phase Response Factor (APRF)/Stat3 Transcription Factor by Growth Hormone [PDF]

Journal of Biological Chemistry, 1995
The mechanism by which the binding of growth hormone (GH) to its cell surface receptor elicits changes in gene transcription are largely unknown. The transcription factor Stat1/p91 has been shown to be activated by GH. Here we show that acute phase response factor or Stat3 f1p4an antigenically related protein), is also activated by GH.

L3MBTL3 and STAT3 collaboratively upregulate SNAIL expression to promote metastasis in female breast cancer

Nature Communications
The STAT3 pathway promotes epithelial–mesenchymal transition, migration, invasion and metastasis in cancer. STAT3 upregulates the transcription of the key epithelial–mesenchymal transition transcription factor SNAIL in a DNA binding-independent manner ...
