关于RNA pyrophosphohydrolase: Messenger RNA (mRNA) degradation plays a key role in the control of gene expression in all organisms by limiting the number of times that each mRNA molecule can be used as a template for protein synthesis. RNA pyrophosphohydrolase, also called RppH, is a master regulator of 5-dependent mRNA decay. It accelerates the degradation of transcripts by removing pyrophosphate from the 5-end of triphosphorylated RNA, leading to a more labile monophosphorylated state that can stimulate subsequent ribonuclease cleavage. RppH preferentially hydrolyzes diadenosine penta-phosphate with ATP as one of the reaction products, and can be able to hydrolyze diadenosine hexa- and tetra-phosphate. However, this protein has no activity on diadenosine tri-phosphate, ADP-ribose, NADH and UDP-glucose. In the meningitis causing strain E.coli K1, it has been shown to play a role in HBMEC (human brain microvascular endothelial cells) invasion in vitro.

关于GLIPR1: Glioma Pathogenesis-Related Protein 1 (GLIPR1) is a member of the CRISP family. It is a single-pass membrane protein with 266 amino acids. GLIPR1 is highly expressed in the lung and kidney and lowly expressed in the heart and liver. It is also highly expressed in cell lines that are derived from nervous system tumors arising from glia; conversely, it is lowly expressed in non-glial-derived nervous system tumor cell lines. GLIPR1 is only expressed in brain tumor glioblastoma multiforme/astrocytoma and not expressed in other nervous system tumors nor normal adult or fetal tissues.
