Dataset Information

Hepatic SILAC proteomic data from PANDER transgenic model.

ABSTRACT: This article contains raw and processed data related to research published in "Quantitative Proteomic Profiling Reveals Hepatic Lipogenesis and Liver X Receptor Activation in the PANDER Transgenic Model" (M.G. Athanason, W.A. Ratliff, D. Chaput, C.B. MarElia, M.N. Kuehl, S.M., Jr. Stevens, B.R. Burkhardt (2016)) [1], and was generated by "spike-in" SILAC-based proteomic analysis of livers obtained from the PANcreatic-Derived factor (PANDER) transgenic mouse (PANTG) under various metabolic conditions [1]. The mass spectrometry output of the PANTG and wild-type B6SJLF mice liver tissue and resulting proteome search from MaxQuant 1.2.2.5 employing the Andromeda search algorithm against the UniprotKB reference database for Mus musculus has been deposited to the ProteomeXchange Consortium (http://www.proteomexchange.org) via the PRIDE partner repository with dataset identifiers PRIDE: PXD004171 and doi:10.6019/PXD004171. Protein ratio values representing PANTG/wild-type obtained by MaxQuant analysis were input into the Perseus processing suite to determine statistical significance using the Significance A outlier test (p<0.05). Differentially expressed proteins using this approach were input into Ingenuity Pathway Analysis to determined altered pathways and upstream regulators that were altered in PANTG mice.

Project description:Male prevalence is an outstanding characteristic of hepatocellular carcinoma (HCC), and the underlying mechanisms for this have remained largely unknown. In the present study, Hras12V transgenic mice, in which hepatocyte-specific expression of the ras oncogene induces male-biased hepatic tumorigenesis, were studied, and altered proteins were detected by two-dimensional fluorescence difference gel electrophoresis (2D-DIGE). Protein samples from hepatic tumor tissues (T) and peritumor tissues (P) of transgenic males and females and the corresponding normal liver tissues (Wt) of nontransgenic males and females were subjected to pairwise comparisons based on proteomic analysis. Among 2381 autodetected protein spots, more than 1600 were differentially expressed based on a pairwise comparison (|ratio| > = 1.5, p < = 0.05). Of these, 180 spots were randomly selected for matrix-assisted laser desorption ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF MS) identification; finally, 89 distinct proteins were obtained. Among these 89 proteins, 7 and 50 proteins were further validated by Western blotting and literature investigation, respectively. Intriguingly, compared with Wt, the altered proteins were relatively concentrated in T in transgenic females but in P in transgenic males. Consistently, the levels of p-ERK and p-mTOR were significantly higher in the T of females compared with that of males. The pathway enrichment assay showed that 5 pathways in males but only 1 in females were significantly altered in terms of the upregulated proteins in T compared with Wt. These data indicate that female hepatocytes are disturbed by oncogenes with great difficulty, whereas male hepatocytes readily do so. In addition, 33 proteins were gender-dependently altered in hepatic tumorigenesis. Moreover, 4% DNA packaging and 4% homeostasis-related functional proteins were found in females but not in males, and more nucleus proteins were found in females (8%) than in males (3%). In conclusion, the proteomic data and comparative analysis presented here offer crucial clues for elucidating the mechanisms that underlie the male prevalence in HCC.
