Androgen-regulation of the protein tyrosine phosphatase PTPRR activates ERK1/2 signalling in prostate cancer cells.
(BioMed Central, 2015-01-16)
BACKGROUND: Androgens drive the onset and progression of prostate cancer (PCa) via androgen receptor (AR) signalling. The principal treatment for PCa is androgen deprivation therapy, although the majority of patients ...
The RNA-binding protein hnRNPA2 regulates β-catenin protein expression and is overexpressed in prostate cancer.
(Taylor & Francis, 2014)
INTRODUCTION: The RNA-binding protein hnRNPA2 (HNRNPA2B1) is upregulated in cancer, where it controls alternative pre-mRNA splicing of cancer-relevant genes. Cytoplasmic hnRNPA2 is reported in aggressive cancers, but is ...
A novel androgen-regulated isoform of the TSC2 tumour suppressor gene increases cell proliferation.
(Impact Journals, 2013-10-13)
TSC2 (Tuberous sclerosis complex 2) is an important tumour suppressor gene, mutations within which are linked to the development of tuberous sclerosis and implicated in multiple tumour types. TSC2 protein complexes with ...
Bistability in the Rac1, PAK, and RhoA Signaling Network Drives Actin Cytoskeleton Dynamics and Cell Motility Switches.
(2016-01-27)
Dynamic interactions between RhoA and Rac1, members of the Rho small GTPase family, play a vital role in the control of cell migration. Using predictive mathematical modeling, mass spectrometry-based quantitation of network ...
The RNA-binding protein Sam68 regulates expression and transcription function of the androgen receptor splice variant AR-V7.
(2015-08-27)
Castration-resistant (CR) prostate cancer (PCa) partly arises due to persistence of androgen receptor (AR) transcriptional activity in the absence of cognate ligand. An emerging mechanism underlying the CRPCa phenotype and ...
Alteration of ribosome function upon 5-fluorouracil treatment favors cancer cell drug-tolerance.
(2022-01-10)
Mechanisms of drug-tolerance remain poorly understood and have been linked to genomic but also to non-genomic processes. 5-fluorouracil (5-FU), the most widely used chemotherapy in oncology is associated with resistance. ...
Building invitro 3D human multicellular models of high-grade serous ovarian cancer.
(2022-03-18)
Three-dimensional (3D), multicellular invitro models provide a useful platform for studying human cancer biology, particularly through deconvolution of the tumor microenvironment, or where animal models do not recapitulate ...
Mouse xenograft modeling of human adult acute lymphoblastic leukemia provides mechanistic insights into adult LIC biology.
(2014-07-03)
The distinct nature of acute lymphoblastic leukemia (ALL) in adults, evidenced by inferior treatment outcome and different genetic landscape, mandates specific studies of disease-initiating mechanisms. In this study, we ...
Engagement of the B-cell receptor of chronic lymphocytic leukemia cells drives global and MYC-specific mRNA translation.
(2016-01-28)
Antigenic stimulation via the B-cell receptor (BCR) is a major driver of the proliferation and survival of chronic lymphocytic leukemia (CLL) cells. However, the precise mechanisms by which BCR stimulation leads to ...
Differential cytopathology and kinetics of measles oncolysis in two primary B-cell malignancies provides mechanistic insights.
(2011-06)
Clinical trials using vaccine measles virus (MV) as anticancer therapy are already underway. We compared the oncolytic potential of MV in two B-cell malignancies; adult acute lymphoblastic leukemia (ALL, an aggressive ...
