MiRNA differentially expressed in P2-peptide and P2S-peptide treated A549 cancer cells.

ABSTRACT: To determine the role of Ago2/Cav1 interaction in Ago2 function, we used miRNA arrays to examine the levels of miRNA in cancer cells whose Ago2/Cav1 interaction was inhibited by P2 or P2S peptides. Disruption of Ago2/Cav1 interaction by P2 peptides resulted in fluctuations in different miRNAs in cancer cells

The peptide repertoire of HLA-B27 includes ligands with lysine at P2 anchor position

Project description:The HLA-B*27 peptidome has drawn significant attention due to the genetic association between some of the HLA-B*27 alleles and the inflammatory rheumatic disease ankylosing spondylitis (AS). The role of HLA-B*27 in this condition is not known yet. This study aims to expand the known limits of the HLA-B*27 peptidome in order to facilitate selection and testing of new peptides, possibly implicated with the disease. The HLA peptidomes of HeLa and C1R cell lines stably transfected with the AS-associated HLA-B*27:05 allele, the non-associated HLA-B*27:09 allele, or their mutants with Cysteine 67 replaced by Serine (C67S), were analyzed on a very large scale. In addition, the peptidomes of HLA-B*27:05 and HLA-B*27:05-C67S were analyzed from transgenic rats’ spleens. The results indicate that a fraction of HLA-B*27 peptides contain lysine at their second position (P2), in addition to the more commonly found peptides with arginine, or the less common glutamine located at this anchor position. Furthermore, the C67S mutation increases the percentages of peptides with glutamine or lysine at their P2 position, in both HLA-B*27:05 and HLA-B*27:09. Therefore, peptides with P2 lysine should be considered as valid ligands of HLA-B*27 molecules and taken into account while looking for candidate for arithrogenic peptides.

Transcriptome expression pattern of E11.5 PGCs, P2 GSCs, and CD49f+GSCs.

Project description:The cell identities of CD49f+GSCs were further identified by comparing them with the E11.5 PGCs and P2 GSCs. The transcriptomic analysis revealed that the CD49f+GSCs had 1/3 similar genes profile to the E11.5 PGCs and P2 GSCs. Further gene ontology (GO) analysis demonstrated that the E11.5 PGCs, P2 GSCs, and CD49f+GSCs shared the partial similar gene expression profile of pluripotency regulation signaling pathway, PI3K-AKT signaling, chemokine signaling, and HIF-1 signaling.

Sulfolobus solfataricus P2 growth curve, tiling arrays

Project description:Experimentally mapped transcriptome structure of Sulfolobus solfataricus P2 by hybridizing total RNA (including RNA species <200 nt) to genome-wide high-density tiling arrays (60 mer probes tiled every 25 nt). Sulfolobus solfataricus P2 growth curve experiments were conducted in batch culture. Reference samples were cultured at mid-log phase (OD600 = 0.312). Eight samples were collected that spanned the key phases of the growth curve. Total RNA from samples of growth curve and reference were directly labeled with Cy3 or Cy5, and were hybridized to the tiling array. Dye-flip experiments were done for each sample. Log ratios were calculated for each probe (growth curve sample/reference). Transcriptome browser is available at http://baliga.systemsbiology.net/enigma/.
