The downregulation of TRIM52 in lung cancer cells significantly suppressed the proliferation of lung cancer cells, arrested the cell cycle at the G1 phase and was accompanied by a decrease in the levels of β‑catenin, proliferating cell nuclear antigen, c‑Myc and Cyclin D1 proteins. Furthermore, we found that apoptosis was induced even 1 h after ATX-101 addition, and that apoptotic cells were found in all phases of the cell cycle (Figures 3B and C). Tumor cells express high levels of PCNA, identifying it as … We subsequently tested these peptides for cellular import and biological activity and selected one lead candidate, ATX-101. APIM-YFP interacts directly with PCNA via the APIM sequence, and mutation in the conserved aromatic amino acid 4 in APIM (F/W/Y to A) abolished this interaction and the ability to sensitize cells to chemotherapeutics [12].
PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics.
A log rank test was performed to compare the overall survival (OS) of patients with high/low expression of PCNA. Ball (University of Birmingham, United Kingdom) and RPMI-8226 (ATCC CCL-155) and U937 (ATCC CRL-1593.2) are from American Type Culture Collection (Manassas, VA, USA). The CCND1 (PRAD1) oncogene, encoding cyclin D1, was first identified as a human oncogene through its involvement in parathyroid tumorigenesis. Multiple myeloma (MM) is a cancer with clonal proliferation of malignant plasma cells that accounts for about 13% of hematological cancers. APIM Therapeutics is a spin-off company of the Norwegian University of Science and Technology, and was a co-funder for this study.

Further understanding of the mechanism underlying enhanced cell growth will be important in identifying novel prognostic markers and therapeutic targets. PCNA leads the way in CVD prevention through support, education and practice resources. Upon binding, cyclins activate their CDK partners, which can then phosphorylate their protein targets.
Thus, PCNA likely has several functions outside the nucleus and beyond DNA replication and repair.

[4], Many proteins interact with PCNA via the two known PCNA-interacting motifs PCNA-interacting peptide (PIP) box[5] and AlkB homologue 2 PCNA interacting motif (APIM). The functionality of PCNA in the cell depends on its ability to bind and recruit other proteins. Substitution of primary antibody by PBS or isotype control antibody was done for negative controls. broad scope, and wide readership – a perfect fit for your research every time. Yes These slides were counterstained with hematoxylin (Vector Laboratories) and then cleared in alcohol and xylene. Michele T. Pritchard, Udayan Apte, in Liver Regeneration, 2015. We added an acetyl to the N-terminal M of the peptide in order to increase the stability. Paraffin-embedded tissues cut into 3-μm sections were placed on glass slides and incubated in xylene twice for 10 min each to remove the paraffin.
