CHPP chr 1,8,20 proteome dataset using the HCC cell lines of MHCC97H and HCCLM3, instrument is Q Exactive, part 1 of 3


ABSTRACT: The fresh cells as described above were harvested and lysed in buffer containing 8 M Urea, 50 mM NH4HCO3 and 5 mM IAA. The total cell lysates were centrifuged with 12,000 g for 10 min at 4 degrees Celsius to remove cell debris, and 1.5 mg proteins for each cell line were followed by sequential in-solution protein digestion by Lys-C and trypsin at 37 degrees Celsius, respectively. The tryptic peptides were cleaned by C18 Sep-Pak column (Waters UK Ltd, Manchester, UK).

The mass spectrometer used in this dataset was Q-Exactive. The dataset was produced with two technical replicates and 24 fractions per repeat. The database searching procedure was achieved using Mascot v2.3. The database is Swiss-prot (release 2013 -6).

We upgraded the preliminary CCPD 1.0 to CCPD 2.0 using the latest deep-profiling proteome (CCPD 2013) of three hepatocellular carcinoma (HCC) cell lines, namely, Hep3B, MHCC97H, and HCCLM3 (ProteomeXchange identifiers: PXD000529, PXD000533, and PXD000535). CCPD 2.0 totally covered 63.6% (438/689) of Chr. 8-coded proteins and 62.6% (439/701) of Chr. 8-coded protein-coding genes. Interestingly, we found that the missing proteins exhibited a tendency to form a cluster region in chromosomes, such as  ...[more]
