A pan-cancer analysis of the oncogenic role of dual-specificity tyrosine (Y)-phosphorylation- regulated kinase 2 (DYRK2) in human tumors.

Although there have been studies correlating DYRK2 with a number of human cancers, there has been no pan-cancer analysis. Therefore, through the TCGA database, we conducted a related study on the expression of DYRK2 in cancers.The expression of DYRK2 is obviously increased in some cancers, while the opposite is true in others, and there is a clear association between its expression and the prognosis of cancer patients.

Protective effect of Achyranthes bidentata polypeptides on NMDA-mediated injury is developmentally regulated via modulating NR2A and NR2B differentially.

Background: Achyranthes bidentata polypeptides (ABPPs) are a potent intervention for excitotoxicity-related disorders such as Parkinson's disease and ischemic stroke. Previous work suggests that overstimulation of N-methyl-D-aspartate (NMDA) receptors plays a critical role in excitotoxicity, and expression of NR2 subunit variations is developmentally regulated. Our current study focused on neuroprotection of ABPPs on cultured neurons by modulation of NR2A and NR2B differentially.

polypeptides prevent apoptosis by inhibiting the glutamate current in cultured hippocampal neurons.

Glutamate-induced excitotoxicity plays a critical role in the neurological impairment caused by middle cerebral artery occlusion. Achyranthes bidentata polypeptides have been shown to protect against neurological functional damage caused by middle cerebral artery occlusion, but the underlying neuroprotective mechanisms and the relationship to glutamate-induced excitotoxicity remain unclear. Therefore, in the current study, we investigated the protective effects of Achyranthes bidentata polypeptides against glutamate-induced excitotoxicity in cultured hippocampal neurons.

Upregulated Expression of TRIM32 Is Involved in Schwann Cell Differentiation, Migration and Neurite Outgrowth After Sciatic Nerve Crush.

Tripartite motif containing 32 (TRIM32), a member of the tripartite motif (TRIM) family, plays an indispensable role in myoblast proliferation. It also regulates neuron and skeletal muscle stem cell differentiation. Although it is of great importance, we know little about the roles of TRIM32 during peripheral nervous system injury.

Spatiotemporal expression of KHSRP modulates Schwann cells and neuronal differentiation after sciatic nerve injury.

K-homology splicing regulator protein (KHSRP), a multifunctional RNA-binding protein, was originally thought to primarily control mRNA decay. KHSRP was shown to be involved in p38MAPK, NF-κB and the JAK2-STAT-1a pathways. Besides, KHSRP regulated neuronal localization of beta-actin and microtubule-associated protein 2 (MAP2) mRNAs, respectively.

Changes in the Foxj1 expression of Schwann cells after sciatic nerve crush.

Foxj1 is a member of the Forkhead box family of transcription factors expressed in multiple tissues during development and a major regulator of cilia development. It was reported that Foxj1 has a significant up-regulation after traumatic brain injury and plays an important role in central nervous system injury and repair. However, its expression and function in the peripheral nervous system lesion are not well understood.

Temporal-spatial expressions of Spy1 in rat sciatic nerve after crush.

As a novel cell cycle protein, Spy1 enhances cell proliferation, promotes the G1/S transition as well as inhibits apoptosis in response to UV irradiation. Spy1 levels are tightly regulated during mammary development, and overexpression of Spy1 accelerates tumorigenesis in vivo. But little is known about the role of Spy1 in the pathological process of damage and regeneration of the peripheral nervous system.
