Intended Use

This antibody pair set comes with matched antibody pair to detect and quantify protein level of human PYCR1.

General Description

This gene encodes an enzyme that catalyzes the NAD(P)H-dependent conversion of pyrroline-5-carboxylate to proline. This enzyme may also play a physiologic role in the generation of NADP(+) in some cell types. The protein forms a homopolymer and localizes to the mitochondrion. Alternative splicing results in multiple transcript variants.

Reconstitution And Storage

Store reagents of the antibody pair set at -20°C or lower. Please aliquot to avoid repeated freeze thaw cycle. Reagents should be returned to -20°C storage immediately after use.

Abstract

Proline metabolism is linked to hyperprolinemia, schizophrenia, cutis laxa, and cancer. In the latter case, tumor cells tend to rely on proline biosynthesis rather than salvage. Proline is synthesized from either glutamate or ornithine; both are converted to pyrroline-5-carboxylate (P5C), and then to proline via pyrroline-5-carboxylate reductases (PYCRs). Here, the role of three isozymic versions of PYCR was addressed in human melanoma cells by tracking the fate of C-13-labeled precursors. Based on these studies we conclude that PYCR1 and PYCR2, which are localized in the mitochondria, are primarily involved in conversion of glutamate to proline. PYCRL, localized in the cytosol, is exclusively linked to the conversion of ornithine to proline. This analysis provides the first clarification of the role of PYCRs to proline biosynthesis.

Abstract

PYCR1 is over-expressed in non-small-cell lung cancer (NSCLC) and its high expression accelerates the progression of NSCLC. However, the underlying mechanisms of PYCR1 in NSCLC progression remain poorly understood. Our study determined the mechanisms of PYCR1 in promotion of the occurrence and development of NSCLC in vitro and in vivo. Firstly, the expression patterns of PYCR1 in NSCLC tissues and cells were determined by RT-PCR, western blot and immunohistochemistry. Then, the effects of PYCR1 on cell proliferation and apoptosis were evaluated by CCK-8 and flow cytomery assays. Finally, we explored the up-regulatory microRNAs (miRs) of PYCR1 and determined if MAPK pathway involved in this process. PYCR1 expression was elevated in NSCLC tissue samples and cells, and the high expression of PYCR1 closely associated with patients' advanced clinical process and poor outcome. Up-regulation of PYCR1 significantly increased the expression of p38 and promoted its nuclear accumulation. Besides, PYCR1 expression was negatively regulated by miR-488, and up-regulation of miR-488 significantly inhibited cell proliferation and tumorigenesis and increased cell apoptosis, and decreased p38 expression and its nuclear accumulation, whereas up-regulation of PYCR1 rescued these results induced by miR-488 over-expression. Collectively, these data suggest the mechanism of PYCR1 in promotion of NSCLC progression. PYCR1 is negatively regulated by miR-488 and then promotes the occurrence and development of NSCLC and activates p38 MAPK pathway.
