SPRY2 (Sprouty RTK Signaling Antagonist 2)

Variants in FGFR signaling pathway-related factors were significantly associated with capecitabine-induced HFS.

In NB, SPRY2 acts as a tumor suppressor, whereas the effects of SPRY1, -3, and -4 in NB have not been investigated so far, although the survival analysis revealed increased survival of NB patients with low SPRY3 levels in different datasets. Thus, this review demonstrates the requirement for further studies about the functions of the SPRY proteins in tumors of the nervous system to define their clinical relevance as potential therapeutic targets in the future.

Finally, SPRY2 homo- and hetero-oligomerizes with SPRY4. We propose that active K-Ras recruits SPRY2 dimers to the membrane, where they block Ras effector access.

Few individual genes significantly predicted survival in the larger cohorts, and none in the Danish cohort. However, the clinical implication of this needs further investigation.

Mechanistically, dual inhibition of XIAP and SHP2 by embelin lessens the proliferation and metastasis, activates senescence and endogenous apoptosis, inhibits cancer-related RAS/mitogen-activated protein kinase (MAPK), phosphoinositide-3-kinase (PI3K)/AKT, Janus kinase/signal transducers and activators of transcription (JAK/STAT), wingless-related integration site (Wnt), and nuclear factor kappa B (NF-κB) signaling pathways, and overcomes compensatory feedback in the MAPK signals through the modulation of mitogen-inducible gene-6 (MIG-6) and SPROUTY2 (SPRY2). Collectively, SHP2 and XIAP are potential synthetic lethal partners, and embelin warrants further development as a novel therapeutic option for alleviating KRAS-mutant NSCLC by cotargeting SHP2 and XIAP.

Using multiple datasets and methods, eight protein-protein pairs were identified as having causal associations with HCC. Protein-protein interactions can provide meaningful findings beyond simple pQTL analysis.

Finally, Sprouty2 (SPRY2) was verified to be the target gene of miR-27a-3p. In conclusion, activated HSC-derived sEVs with high levels of miR-27a-3p might induce M2 macrophage polarization and promote hepatoma progression, providing new insights into the mechanism of hepatoma progression.

Despite the reduction of FGFR1 protein and the inhibition of FGF signaling, SPRY2-OE increased cell viability, and knockdown of SPRY2 enhanced the sensitivity to cisplatin. These results demonstrate that the inhibitory effect of SPRY2-OE on FGF signaling is at least in part due to the reduction in FGFR1 levels and the decreased binding of PLCγ1 to the receptor.

In conclusion, the identification of Loc646329 as a sponge for miR-21 and its impact on the RAS/MAPK signaling pathway offers new opportunities for the development of innovative therapeutic strategies for OSCC. Further investigations into this regulatory axis may uncover additional targets for precision medicine approaches in the treatment of OSCC.

Though these modifications did not directly overlap with FKBP12 binding residues, they promoted FKBP12 dissociation from RyR1. These findings provide detailed insights into how stable oxidative PTMs on RyR1 residues alter channel gating, advancing our understanding of RyR1-mediated Ca2+ release in conditions associated with oxidative stress and muscle weakness.

SLNCR1 is an oncogene that interacts with DNMT1 to mediate SPRY2 methylation, thereby suppressing SPRY2 expression and promoting the angiogenesis and tumor growth in melanoma. SLNCR1 may serve as a potential target for melanoma treatment.
