SPRY2 Proteine (SPRY2)

Xenopus laevis Sprouty Homolog 2 (Drosophila) (SPRY2) Interaktionspartner

1. Data show that the intracellular domain of PAPC interacts with Sprouty (Spry), and upon binding to PAPC, Spry function is inhibited and PCP signaling is enhanced.

2. Here we show that Xenopus laevis Sprouty2 (XSpry2) controls the duration of ERK (zeige MAPK1 Proteine) activity and thereby contributes to the establishment of dorsoventral patterning during mesoderm formation.

Human Sprouty Homolog 2 (Drosophila) (SPRY2) Interaktionspartner

1. activation of ERK1/2 signaling was required for hCG-induced up-regulation of SPRY2 expression. Further, SPRY2 knockdown attenuated the AREG-induced COX-2 expression and PGE2 production by inhibiting AREG-activated ERK1/2 signaling.

2. Result demonstrated that SPRY2 low-expression was significantly associated with unfavorable prognosis of gastric adenocarcinoma and that SPRY2 could inhibit FGFR2 (zeige FGFR2 Proteine)-induced ERK (zeige EPHB2 Proteine) phosphorylation and suppress FGFR2 (zeige FGFR2 Proteine)-elicited gastric cancer cell proliferation and invasion.

3. Sprouty2 inhibits amphiregulin (zeige AREG Proteine)-induced down-regulation of E-cadherin (zeige CDH1 Proteine) and cell invasion in human ovarian cancer cells.

4. Sprouty2 (Spry2), a negative regulator of the extracellular signal regulated kinase/mitogen-activated protein kinase (zeige MAPK1 Proteine) (Erk/MAPK (zeige MAPK1 Proteine)) signalling pathway, was a downstream target of miR (zeige MLXIP Proteine)-122-5p possibly involved in regulating the keratinocyte proliferation.

5. results shows the involvement of Spry2 in regulation of FosB (zeige FOSB Proteine) and Runx2 (zeige RUNX2 Proteine) genes, MAPK (zeige MAPK1 Proteine) signaling and proliferation of mesenchymal stem cells.

6. MYB (zeige MYB Proteine) acts on MAPK (zeige MAPK1 Proteine) signaling by directly regulating transcription of the gene encoding the negative modulator SPRY2.

7. ZEB1 upregulation by SPRY2 results from the combined induction of ETS1 transcription factor and the repression of microRNAs (miR-200 family, miR-150) that target ZEB1 RNA. Moreover, SPRY2 increased AKT activation by epidermal growth factor, whereas AKT and also Src inhibition reduced the induction of ZEB1.

8. upregulated in human CRC (zeige CALR Proteine). Suppression of SPRY2 repressed AKT2 (zeige AKT2 Proteine) and EMT (zeige ITK Proteine)-inducing transcription factors and significantly increased E-cadherin (zeige CDH1 Proteine) expression. Concurrent downregulation of SPRY1 (zeige SPRY1 Proteine) and SPRY2 also increased E-cadherin (zeige CDH1 Proteine) and suppressed mesenchymal markers in colon cancer cells.

9. In cells harbouring a K-Ras (zeige HRAS Proteine) mutation the serine conversion weakens the reduction of migration velocity indicating that dependent on the status of K-Ras (zeige HRAS Proteine) the serine influences Sprouty2 functions differently.

10. Increased nuclear localization of p21(WAF1/CIP1 (zeige CDKN1A Proteine)) in SPRY2 downregulated colon cancer cells may explain the inhibition of cell proliferation in colon cancer cells.

Mouse (Murine) Sprouty Homolog 2 (Drosophila) (SPRY2) Interaktionspartner

1. These results identify Spry2 as a critical regulator of endochondral bone formation that modulates signaling in both osteoblast and chondrocyte lineages.

2. MYB (zeige MYB Proteine) acts on MAPK (zeige MAPK1 Proteine) signaling by directly regulating transcription of the gene encoding the negative modulator SPRY2.

3. Spry2 is a novel unfolded protein response target and its upregulation is dependent on PERK (zeige EIF2AK3 Proteine). Knockdown of Spry2 resulted in reduced expression of Serca2 (zeige ATP2A2 Proteine), reduced endoplasmic reticulum calcium levels, and induction of the UPR. Spry2 deletion in the adult mouse beta-cell caused hyperglycemia and hypoinsulinemia.

4. these results establish SPRY2 as a critical negative regulator of BCR (zeige BCR Proteine)-mediated MAPK-Erk (zeige MAPK1 Proteine) signaling in chronic lymphocytic leukemia , thereby providing one of the molecular mechanisms to explain the clinical heterogeneity of chronic lymphocytic leukemia.

5. In the present study, it is demonstrated that Spry2 and -4 participate in KA induced neurodegeneration possibly through inhibition of ERK (zeige EPHB2 Proteine) signaling.

6. Study revealed that suppression of Spry2 expression induced proliferation and differentiation of osteoblastic cells upon bFGF (zeige FGF2 Proteine) and EGF (zeige EGF Proteine) stimulation, whereas it diminished proliferation of gingival epithelial cells.

7. Cosuppression of Sprouty and Sprouty-related negative regulators of FGF signalling in prostate cancer

8. in embryos with lower Spry2;Spry4 (zeige SPRY4 Proteine) gene dosages, we observed a non-fusion of original R2 and M1 Shh (zeige SHH Proteine) signaling domains with consequent formation of a supernumerary tooth primordium from the isolated R2 bud

9. The data showed enhanced axon outgrowth and improved long-distance axon regeneration in sprouty2 deficient mice

10. Sprouty2 acts as an inhibitor of CrkL-Rap1 signaling.
