SUMOylation is required for optimal TRAF3 signaling capacity.
(2013)
TNF receptor-associated factors (TRAFs) are multifunctional adaptor proteins involved in temporal and spatial coordination of signals necessary for normal immune function. Here, we report that TRAF3, a TRAF family member ...
TGF-β induces miR-100 and miR-125b but blocks let-7a through LIN28B controlling PDAC progression.
(2018-05-10)
TGF-β/Activin induces epithelial-to-mesenchymal transition and stemness in pancreatic ductal adenocarcinoma (PDAC). However, the microRNAs (miRNAs) regulated during this response have remained yet undetermined. Here, we ...
Nicotine promotes initiation and progression of KRAS-induced pancreatic cancer via Gata6-dependent dedifferentiation of acinar cells in mice.
(2014-11)
BACKGROUND & AIMS: Although smoking is a leading risk factor for pancreatic ductal adenocarcinoma (PDAC), little is known about the mechanisms by which smoking promotes initiation or progression of PDAC. METHODS: We studied ...
Chloroquine targets pancreatic cancer stem cells via inhibition of CXCR4 and hedgehog signaling.
(2014-07)
Pancreatic ductal adenocarcinoma is one of the deadliest carcinomas and is characterized by highly tumorigenic and metastatic cancer stem cells (CSC). CSCs evade available therapies, which preferentially target highly ...
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 ...
Nfix Promotes Survival of Immature Hematopoietic Cells via Regulation of c-Mpl.
(2018-02-12)
Hematopoietic stem and progenitor cells (HSPCs) are necessary for life-long blood production and replenishment of the hematopoietic system during stress. We recently reported that nuclear factor I/X (Nfix) promotes HSPC ...
PKCɛ switches Aurora B specificity to exit the abscission checkpoint.
(2016-12-22)
The 'NoCut', or Aurora B abscission checkpoint can be activated if DNA is retained in the cleavage furrow after completion of anaphase. Checkpoint failure leads to incomplete abscission and a binucleate outcome. These ...
The outcome of B-cell receptor signaling in chronic lymphocytic leukemia: proliferation or anergy.
(2014-07)
Biologists and clinicians agree that the B-cell receptor influences the behavior of chronic lymphocytic leukemia, and promising new drugs are aimed at receptor-associated kinases. Engagement of surface immunoglobulin by ...
Inhibition of p38 mitogen-activated protein kinase unmasks a CD30-triggered apoptotic pathway in anaplastic large cell lymphoma cells.
(2007-02)
CD30, a non-death domain-containing member of the tumor necrosis factor receptor superfamily, triggers apoptosis in anaplastic large cell lymphoma cells. The CD30 signaling pathways that lead to the induction of apoptosis ...
