P-Rex1 Expression in Invasive Breast Cancer in relation to Receptor Status and Distant Metastatic Site

open access: yesInternational Journal of Breast Cancer, 2017
Background. Phosphatidylinositol-3,4,5-trisphosphate-dependent Rac exchange factor 1 (P-Rex1) has been implicated in cancer growth, metastasis, and response to phosphatidylinositol 3-kinase (PI3K) inhibitor therapy. The aim of this study was to determine

PDGF regulates guanylate cyclase expression and cGMP signaling in vascular smooth muscle

open access: yesCommunications Biology, 2022
PDGF reduces expression of nitric oxide-sensitive soluble guanylyl cyclase (NO-sGC) through PI3K-P-Rex1-Rac1 signaling in vascular smooth muscle cells.

Co-expression networks in generation of induced pluripotent stem cells. [PDF]

open access: yes, 2016
We developed an adenoviral vector, in which Yamanaka's four reprogramming factors (RFs) were controlled by individual CMV promoters in a single cassette (Ad-SOcMK). This permitted coordinated expression of RFs (SOX2, OCT3/4, c-MYC and KLF4) in a cell for

A direct physical interaction between Nanog and Sox2 regulates embryonic stem cell self-renewal [PDF]

open access: yes, 2013
Embryonic stem (ES) cell self-renewal efficiency is determined by the Nanog protein level. However, the protein partners of Nanog that function to direct self-renewal are unclear.

Retroposition and evolution of the DNA-binding motifs of YY1, YY2 and REX1 [PDF]

open access: yesNucleic Acids Research, 2007
YY1 is a DNA-binding transcription factor found in both vertebrates and invertebrates. Database searches identified 62 YY1 related sequences from all the available genome sequences ranging from flying insects to human. These sequences are characterized by high levels of sequence conservation, ranging from 66% to 100% similarity, in the zinc finger DNA ...

Impacts of Stress Caused by Copper Sulfate (CuSO4) on the Genome of the Tambaqui (Colossoma macropomum): Quantification of Rex1 and Heterochromatic Profile

open access: yesBrazilian Archives of Biology and Technology, 2022
The transposable elements are known by their ability to move and integrate into the genome of the host organism. They are classified in retrotransposons class I, which has, as intermediate of the transposition, the RNA and retrotransposons class II ...

RNF12 X-linked intellectual disability mutations disrupt E3 ligase activity and neural differentiation [PDF]

open access: yes, 2018
Summary: X-linked intellectual disability (XLID) is a heterogeneous syndrome affecting mainly males. Human genetics has identified >100 XLID genes, although the molecular and developmental mechanisms underpinning this disorder remain unclear.

Xist and Tsix transcription dynamics is regulated by the X-to-autosome ratio and semistable transcriptional states [PDF]

open access: yes, 2016
In female mammals, X chromosome inactivation (XCI) is a key process in the control of gene dosage compensation between Xlinked genes and autosomes.

Control of Saccharomyces cerevisiae pre-tRNA processing by environmental conditions. [PDF]

open access: yes, 2016
tRNA is essential for translation and decoding of the proteome. The yeast proteome responds to stress and tRNA biosynthesis contributes in this response by repression of tRNA transcription and alterations of tRNA modification.

Regulation of P-Rex1 by Phosphatidylinositol (3,4,5)-Trisphosphate and Gβγ Subunits [PDF]

open access: yesJournal of Biological Chemistry, 2005
P-Rex1 is a guanine-nucleotide exchange factor (GEF) for the small GTPase Rac. We have investigated here the mechanisms of stimulation of P-Rex1 Rac-GEF activity by the lipid second messenger phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P3) and the Gbetagamma subunits of heterotrimeric G proteins. We show that a P-Rex1 mutant lacking the PH
