Osr1/Osr2 normally repress bmp4 (show BMP4 Proteins) expression in the lateral plate mesoderm prior to respiratory specification.
nephrogenic transcription factors (osr1, osr2, hnf1b (show HNF1B Proteins), lhx1 (show LHX1 Proteins), pax8 (show PAX8 Proteins))play important role in nephrogenesis but have no pronephros induction potential upon overexpression; they activate transcription cascades reflecting activation by activin A (show INHBA Proteins), retinoic acid
Both SPAK (show STK39 Proteins) and OSR1 (show OXSR1 Proteins) kinases entering cells through exosomes are preferentially expressed at the plasma membrane and that the kinases in exosomes are functional and maintain NKCC1 (show SLC12A2 Proteins) in a phosphorylated state.
In summary, our study implicated a gene network involving Tbx5 (show TBX5 Proteins), Osr1 (show OXSR1 Proteins) and Pcsk6 interaction in second heart field for atrial septation, providing a molecular framework for understanding the role of Tbx5 (show TBX5 Proteins) in congenital heart disease ontogeny.
SPAK (show STK39 Proteins) and OSR1 (show OXSR1 Proteins) are both stimulators of Kir2.1 (show KCNJ2 Proteins) activity.
SPAK (show STK39 Proteins) and OSR1 (show OXSR1 Proteins) are powerful stimulators of the intestinal Na+-coupled phosphate co-transporter NaPi-IIb (show SLC34A2 Proteins)
OSR1 (show OXSR1 Proteins) protein has both the potential to up-regulate KCNQ1 (show KCNQ1 Proteins)/E1 protein abundance in the cell membrane, an effect possibly participating in the regulation of cell volume, excitability, epithelial transport and metabolism.
SPAK (show STK39 Proteins) and OSR1 (show OXSR1 Proteins) are powerful negative regulators of the excitatory glutamate (show GRIN1 Proteins) transporters EAAT1 (show SLC1A3 Proteins) and EAAT2 (show SLC1A2 Proteins).
SPAK (show STK39 Proteins) and OSR1 (show OXSR1 Proteins) are negative regulators of EAAT3 (show SLC1A1 Proteins) activity
OSR1 has the capacity to downregulate the peptide transporters PEPT1 and PEPT2 by decreasing the carrier protein abundance in the cell membrane
Both, SPAK (show STK39 Proteins) and OSR1 (show OXSR1 Proteins), are negative regulators of the creatine transporter SLC6A8 (show SLC6A8 Proteins)
SPAK (show STK39 Proteins) and OSR1 (show OXSR1 Proteins) are powerful negative regulators of the cell volume regulatory Cl- channel ClC-2 (show CLCN2 Proteins)
Our data reveal that together SPAK (show STK39 Proteins) and OSR1 play essential roles in the pathway along the distal convoluted tubules that responds to fluctuations in plasma potassium
These results indicate that Osr1 and Wt1 (show WT1 Proteins) act synergistically to regulate nephron endowment by controlling metanephric mesenchyme specification during early nephrogenesis.
Tbx5 (show TBX5 Proteins) and Osr1 interact to regulate posterior second heart field cell cycle progression for cardiac septation.
odd-skipped related 1 is involved in regulation of mammalian kidney development
ROMK1 (show KCNJ1 Proteins) protein abundance and activity are down-regulated by SPAK (show STK39 Proteins) and OSR1
study identifies a separation of functions for the WNK1 (show WNK1 Proteins)-activated protein kinases OSR1 and SPAK (show STK39 Proteins) in mediating proliferation, invasion, and gene expression in endothelial cells
WNK 1 (show WNK1 Proteins), 3, 4, OSR1, and SPAK (show STK39 Proteins) signaling system known to play a role in regulating the phosphorylation status, and hence activity of the CCCs in other tissues, is also present in the rat and human lenses.
Osr1 plays crucial roles in Six2 (show SIX2 Proteins)-dependent maintenance of nephron progenitors during mammalian nephrogenesis.
Data indicate that Activin A (show INHBA Proteins) and retinoic acid (RA) induced theto embryonic stem cells (mESCs) expression of marker genes and proteins for intermediate mesoderm, odd-skipped related 1 (Osr1) and Wilms Tumor 1 (Wt1 (show WT1 Proteins)).
Odd-skipped related-1 controls neural crest chondrogenesis during tongue development.
findings identify osr1 as a Nodal-induced, negative feedback regulator of Nodal signaling that acts at the earliest stages of endoderm differentiation to limit the number of endoderm progenitors.
Our results place osr1 in a framework of transcriptional regulators that control the expression of podocin and nephrin (show NPHS1 Proteins) and thereby mediate podocyte differentiation.
The Osr1 and Osr2 genes act in the pronephric anlage downstream of retinoic acid signaling and upstream of Wnt2b (show WNT2B Proteins) to maintain pectoral fin development.
osr1 reveals a novel role for endoderm in regulating kidney versus vascular cell fate.
