Abstract
To investigate the existence and their potential biological roles of mitochondrial phosphoproteins (mtPPs) in human ovarian carcinoma (OC), mitochondria purified from OC and control tissues were analyzed with TiO2 enrichment-based iTRAQ quantitative proteomics. Totally 67 mtPPs with 124 phosphorylation sites were identified, which of them included 48 differential mtPPs (mtDPPs). Eighteen mtPPs were reported previously in OCs, and they were consistent in this study compared to previous literature. GO analysis revealed those mtPPs were involved in multiple cellular processes. PPI network indicated that those mtPPs were correlated mutually, and some mtPPs acted as hub molecules, such as EIF2S2, RPLP0, RPLP2, CFL1, MYH10, HSP90, HSPD1, PSMA3, TMX1, VDAC2, VDAC3, TOMM22, and TOMM20. Totally 32 mtPP-pathway systems (p<0.05) were enriched and clustered into 15 groups, including mitophagy, apoptosis, deubiquitination, signaling by VEGF, RHO-GTPase effectors, mitochondrial protein import, translation initiation, RNA transport, cellular responses to stress, and c-MYC transcriptional activation. Totally 29 mtPPs contained a certain protein domains. Upstream regulation analysis showed that TP53, TGFB1, dexamethasone, and thapsigargin might act as inhibitors, and L-dopa and forskolin might act as activators. This study provided novel insights into mitochondrial protein phosphorylations and their potential roles in OC pathogenesis and offered new biomarker resource for OCs.

Khalid M, Driessen TM, Lee JS, Tejwani L, Rasool A, Saqlain M, Shiaq PA, Hanif M, Nawaz A, DeWan AT, Raja GK, Lim J. Association of CACNA1C with bipolar disorder among the Pakistani population. Gene 2018; 664:119-126. [PMID: 29684488 DOI: 10.1016/j.gene.2018.04.061] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 04/17/2018] [Accepted: 04/19/2018] [Indexed: 10/17/2022]
Abstract
Many single nucleotide polymorphisms (SNPs) have been identified for Bipolar disorder (BD), but association between SNPs and BD can vary depending on the population tested. SNPs rs10994336 and rs9804190 in ANK3 and rs1006737 in CACNA1C have emerged as the most highly replicated SNPs significantly associated with BD. The aim of the present study was to assess the association of these SNPs with BD in the Pakistani population, which has never before been examined. A total of 120 BD and 120 control individuals from Pakistan were examined in this analysis. Genotyping results indicated that rs1006737 in CACNA1C was significantly associated with BD, while rs10994336 or rs9804190 in ANK3 was not significant when examined individually. However, risk score assessment found that the presence of two or more risk alleles was significantly associated with disease, indicating that risk alleles from ANK3 and CACNA1C may additively contribute to BD. A protein-protein interaction network was generated using STRING to probe the relationship between ANK3 and CACNA1C interactors and their associations with BD. While none of the interactors are directly linked to BD, they play a role in pathways linked to BD, including oxytocin and dopamine signaling pathways. Collectively, these results reveal a significant association of CACNA1C with BD among the Pakistani population, extending results from other ethnic groups to the Pakistani population for the first time.
