Characterization of a P-Rex1 gene signature in breast cancer cells

open access: yesOncotarget, 2016
The Rac nucleotide Exchange Factor (Rac-GEF) P-Rex1 is highly expressed in breast cancer, specifically in the luminal subtype, and is an essential mediator of actin cytoskeleton reorganization and cell migratory responses induced by stimulation of ErbB and other tyrosine-kinase receptors.

Inhibition of JAK-STAT ERK/MAPK and Glycogen Synthase Kinase-3 Induces a Change in Gene Expression Profile of Bovine Induced Pluripotent Stem Cells

open access: yesStem Cells International, 2016
Pluripotent stem cells (PSCs) fall in two states, one highly undifferentiated, the naïve state, and the primed state, characterized by the inability to contribute to germinal lineage. Several reports have demonstrated that these states can be modified by

EXPRESSION OF PLURIPOTENCY MARKERS IN REPROGRAMMING WITH TRANSPOSON SYSTEM MURINE FIBROBLASTS [PDF]

open access: yesBiotechnologia Acta, 2013
The search for effective and safe methods to generate induced pluripotent stem cells is especially urgent. In the paper murine embryonic fibro blasts were reprogrammed towards actively proliferating colonies with typical induced pluripotent stem cells ...

Zscan4 Is Activated after Telomere Shortening in Mouse Embryonic Stem Cells

open access: yesStem Cell Reports, 2016
ZSCAN4 is a DNA-binding protein that functions for telomere elongation and genomic stability. In vivo, it is specifically expressed at the two-cell stage during mouse development. In vitro, it is transiently expressed in mouse embryonic stem cells (ESCs),

CryoSift: an accessible and automated CNN‐driven tool for cryo‐EM 2D class selection

open access: yesActa Crystallographica Section F, Volume 81, Issue 12, Page 517-526, December 2025.
CryoSift is a CNN‐based tool that assesses the quality of 2D class averages. The incorporation of CryoSift into cryoSPARC workflows enables automated particle‐stack cleaning.Single‐particle cryo‐electron microscopy (cryo‐EM) has become an essential tool in structural biology.

Secure Degrees of Freedom for Gaussian Channels with Interference: Structured Codes Outperform Gaussian Signaling

open access: yes, 2009
In this work, we prove that a positive secure degree of freedom is achievable for a large class of Gaussian channels as long as the channel is not degraded and the channel is fully connected.

Organ‐Specific Dedifferentiation and Epigenetic Remodeling in In Vivo Reprogramming

open access: yesAging Cell, Volume 24, Issue 11, November 2025.
Transient in vivo expression of Yamanaka factors (OSKM) enhances regenerative competence and rejuvenation across multiple tissues. We highlight mechanistic links between injury‐induced dedifferentiation and OSKM reprogramming, while emphasizing safety challenges and the need for precise spatiotemporal control to enable clinical translation.

Response to BMP4 signalling during ES cell differentiation defines intermediates of the ectoderm lineage [PDF]

open access: yes, 2010
The formation and differentiation of multipotent precursors underlies the generation of cell diversity during mammalian development. Recognition and analysis of these transient cell populations has been hampered by technical difficulties in accessing ...

Identification and Characterization of a LIF-STAT3/Activin-Smad2/3 Dual Responsive Pluripotent Stem Cell State

open access: yes, 2011
The medical and bioindustrial applications of pluripotent stem cells rely on our understanding of their biology. Pluripotent stem cell lines derived from embryos in different stages depend on distinct signalling pathways.
