human alveolar epithelial cell HAEC exposed to hypoxia, RhoA/ROCK activation is necessary for Na,K-ATPase endocytosis via a mechanism that requires mitochondrial reactive oxygen species
mRNA levels of RasL10B are down-regulated in all breast cancer cells tested (HBL100, MCF7, MDA-MB-468, MDA-MB-231 and MDA-MB-435. RasL10B) is a member of ras superfamily with tumor suppressor potential
GhRac1 is highly expressed during the elongation stage of fiber development with expression decreasing dramatically when the rate of the fiber elongation declines
important role for Rho-GTPases in the morphology and function of glomerular epithelial cells. Activation of RhoA appears to be protective against complement-mediated injury
lung cancer patients with metastasis and poor survival show low hRAB37 protein expression coinciding with low TIMP1 in tumours, hRAB37 is downregulated mainly by promoter hypermethylation in lung cancer cells and patients, low mRNA expression of hRAB37 gene is associated with tumour metastasis in lung cancer patients
transient transcriptional upregulation of PpARF genes and of PpRAB genes of the A and D clades appears to coincide with peaks of growth speed and sugar accumulation and with the final phases of ripening
a transient increase in Rac activity coupled with a transient decrease in RhoA activity occurs in honey bees with 4 days foraging experience compared with same-aged new foragers
signal relay in which pollen receptor kinase AtPRK2a at the plasma membrane recruits AtRopGEF12 through its C terminus to maintain polar Rop activity in the pollen tube
adjacent, two isoforms of RASL11A transcript with different sizes of 1.6 and 1.2 kb, the abundance of the RASL11A transcript is diminished in prostate tumors in comparison to normal adjacent prostate tissue
smGTP gene displays low levels of expression prior to harvesting and increased 12 h after harvest. Low level of expression as the seed head emerges and shows a strong induction in late to post-anthesis tissues. Surprisingly very little expression is observed in seed heads at the milk and ripe seed head stages. A low level of smGTP expression is observed in stem and leaf tissue at this stage of development
proliferation of dermal fibroblasts is crucial for the maintenance of skin. Rac1 activates proliferation of normal fibroblasts through stimulation of c-myc phosphorylation without affecting ERK1/2 activity
Rac1 appears to be important for parenchyma expansion at the beginning of cytodifferentiation, while RhoC, Cdc42 and the inactive phosphorylated form of Rac1 seemed associated with lumen formation and cell polarization in terminal tubules in the developing submandilbular gland
in the adult mouse brain, Rab23 is detected in betaIII tubulin positive neuronal cell bodies and are most prominent in cortex, hypothalamus and the cerebellum
prepared from tumor-bearing mice ex vivo. Tumor-induced dysregulation of endocytic activity of dendritic cells is mediated by reduced activity of several members of the small Rho GTPase family
RhoV mRNA is maternally expressed and accumulates shortly after gastrulation in the neural crest forming region. Rho functions in pathways that control neural crest cells specification
Ras is detected in glomerular cells, proximal convoluted tubule cells, distal convoluted tubule cells, cortical collecting tubule cells, medullar collecting duct cells, interstitial cells and subcapsular fibroblast. Ras plays a role in renal fibrosis
Ras is detected in medullary endothelial cells, medullary interstitial cells, cortical interstitial cells and glomerular endothelial cells. Ras plays a role in renal fibrosis
TLRs agonists induce changes in the expression of Rap2a in macrophages. In contrast to mRNA levels, Rap2a protein levels are increased after LPS treatments of macrophages
hippocampal neuron. Rnd1 plays a critical role in neuronal activity-dependent dendritic development in hippocampal neurons. Overexpression of Rnd1 promotes dendritic growth and branching in cultured hippocampal neurons. Suppression of endogenous Rnd1 expression by RNA interference significantly inhibits neuronal activity-dependent dendritic development
Rap1 and Rap2 share the ability to suppress synaptic transmission by inhibiting surface expression of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate receptors containing the glutamate receptor alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate receptor subunit GluR2. Rap1 and Rap2 have overlapping but distinct actions that potentially link the inhibition of synaptic transmission with the retraction of axons and dendrites. Rap2 in particular induced the retraction of axons and dendrites and the loss of spines and excitatory synapses, in a cell type-specific and activity-regulated fashion
uninfected normal cells have negligible quantities of mRNA for Rac1, upon infection with Candida albicans a significant increase in the mRNA level is observed

transcript levels and expression of the enzyme are significantly increased in the erythrocytic phase in particular during schizont and gametocyte formation
