Rehmannia glutinosa has important medicinal value; terpenoid is one of the main active components in R. glutinosa. In this study, iTRAQ technique was used to analyze the relative abundance of proteins in roots of R. glutinosa, and 6,752 reliable proteins were quantified. GO enrichment results indicated that most proteins were involved in metabolic process or cellular process, 57.63% proteins had catalytic activity, and 65.80% proteins were enriched in membrane-bounded organe ...[more]

photoaffinity for Puerarin and mouse brainstem

Project description:To elucidate the molecular mechanism mediating the inactivated effect of DMV neurons on fat absorption, we performed an activity-based protein profiling strategy, using Puerarin as a “bait”. The Puerarin-tag probe was synthesized with a photoreactive tag to enrich and visualize target proteins via a photoaffinity chemistry reaction. We verified that probe-tagged Puerarin retains the same effects of increasing fecal lipid excretion as non-tagged Puerarin. Probe-tagged Puerarin was added to the freshly isolated brainstem sample, and 10 doses of non-tagged Puerarin was used as a competitor of probe-tagged Puerarin. Following the photoaffinity reaction, targeted proteins were subsequently assessed by liquid chromatography tandem mass spectrometry (LC-MS).

mRNA expression profiling of mouse microvasculature

Project description:Combination of reverse- and chemical genetic screens reveals a network of novel angiogenesis inhibitors and targets Drug target identification and validation are bottlenecks in the drug discovery process. Accordingly there is a need to develop new methods to facilitate the development of much-needed innovative drugs. We have combined reverse- and chemical genetics to identify new targets modulating blood vessel development. Through mRNA expression profiling in mice we identified 155 drugable gene products that were enriched in the microvasculature. Orthologs of 50 of these candidates were knocked down in a reverse genetic screen in zebrafish. 16 of the 50 genes encoded products that affected angiogenesis. In parallel, screening of 300 known drugs and pharmacologically active compounds in a human cell-based angiogenesis assay identified 11 angiogenesis inhibitors. Strikingly the reverse- and chemical genetic screens identified an overlap of three gene products of the same superfamily of serine/threonine protein phosphatases and two compounds targeting that family. Furthermore, the gene products identified in the reverse genetic screen comprise an interacting network with the targets of the chemical genetic screen. Thus, combining reverse- and chemical genetic screens is a powerful approach to identify novel biological processes and drug targets in vertebrates. Keywords: Cell-type comparison 24 samples were analyzed, representing 8 sample groups. In every sample group, three biological replicates were hybridized separately. The microarrays were hybridized with a Cy3-labeled sample and Cy-5 labeled Common Reference (Universal Mouse Reference RNA, cat. No.: 740100, Stratagene) simultaneously.

Nucleus-Translocated GCLM Promotes Chemoresistance in Colorectal Cancer through a Moonlighting Function

Project description:Emerging evidence indicates that metabolic enzymes perform moonlighting functions during tumor progression, including the modulation of chemoresistance. However, the underlying mechanisms of these functions remain elusive. In this study, utilizing a metabolic CRISPR-Cas9 knockout library screen, we observed that loss of Glutamate-cysteine ligase modifier subunit (GCLM), a rate-limiting enzyme in glutathione biosynthesis, noticeably heightens the sensitivity of colorectal cancer (CRC) cells to platinum-based chemotherapy. Mechanistically, we unveil a noncanonical mechanism through which nuclear GCLM competitively interacts with NF-kappa-B-repressing factor (NKRF), a known inhibitor of NF-κB signaling, to promote NF-κB activity and subsequently facilitate chemoresistance. In response to platinum drug treatment, P38 MAPK phosphorylates GCLM at T17, resulting in its recognition by importin a5 and subsequent nuclear translocation. Furthermore, elevated expression of nuclear GCLM correlates with unfavorable prognosis and poor benefit from standard chemotherapy. Overall, our work shed light on the essential nonmetabolic role and posttranslational regulatory mechanism of GCLM in enhancing NF-κB activity and subsequent chemoresistance.

Cardiac Repair using regenerating neonatal heart tissue-derived extracellular vesicles.

Project description:The neonatal mammalian heart is able to regenerate after injury by inducing cardiomyocyte proliferation. However, this regenerative capacity is virtually lost in the adult mammalian heart. Extracellular vesicles (EVs) have been shown to play an important cardioprotective role in heart repair. Here, we performed proteomic analysis of EVs from neonatal mouse heart tissues (Neo-EVs), EVs regenerated from neonatal heart tissues after apicoectomy (AR-Neo-EVs), and EVs from adult mouse hearts (Adu-EVs), to compare the differential changes in proteins among them.

RNAi profiling by array of human HeLa cells with hnRNP C siRNA knockdown using a splice-junction microarray to detect changes in alternative splicing.

Project description:poly(A)+ RNA samples from hnRNP C siRNA knockdown and control HeLa cells were compared on a splice-junction microarray to detect changes in alternative splicing. Using the ASPIRE3 algorithm, we detected changes in splicing at 1,340 alternative exons. We observed a similar incidence of increased or decreased exon inclusion in hnRNP C knockdown cells, indicating that hnRNP C can either silence or enhance exon inclusion, respectively. We validated changes at 26 exons by RT-PCR with a 92% success rate.
