HIV-1 Tat Binding to PCAF Bromodomain: Structural Determinants from Computational Methods

Biology, 2012
The binding between the HIV-1 trans-activator of transcription (Tat) and p300/(CREB-binding protein)-associated factor (PCAF) bromodomain is a crucial step in the HIV-1 life cycle.

Time changes of symmetric diffusions and Feller measures

, 2005
We extend the classical Douglas integral, which expresses the Dirichlet integral of a harmonic function on the unit disk in terms of its value on boundary, to the case of conservative symmetric diffusion in terms of Feller measure, by using the approach ...

Glycogen Synthase Kinase (GSK) 3β phosphorylates and protects nuclear myosin 1c from proteasome-mediated degradation to activate rDNA transcription in early G1 cells [PDF]

, 2014
Nuclear myosin 1c (NM1) mediates RNA polymerase I (pol I) transcription activation and cell cycle progression by facilitating PCAF-mediated H3K9 acetylation, but the molecular mechanism by which NM1 is regulated remains unclear.

Screening anticancer peptides performance in organotypic prostate tumor‐stroma 3D models

International Journal of Cancer, EarlyView.
What's New? Peptide‐based drugs have emerged as promising anticancer therapies for their potential to disrupt protein–protein interactions. In this study, the authors developed a physiomimetic human 3D prostate cancer spheroid model to assess the efficacy of the CAVPENET peptide in inhibiting tumor growth. Upon incubation with CAVPENET, prostate cancer

Epigenomic Regulation of Androgen Receptor Signaling: Potential Role in Prostate Cancer Therapy. [PDF]

, 2017
Androgen receptor (AR) signaling remains the major oncogenic pathway in prostate cancer (PCa). Androgen-deprivation therapy (ADT) is the principle treatment for locally advanced and metastatic disease.

Intrinsic specificity of a ‘core’ TIP60 acetyltransferase complex in Drosophila

The FEBS Journal, EarlyView.
The intrinsic substrate selectivity of the Drosophila TIP60‐core acetyltransferase was determined using synthetic nucleosome arrays. Targeted mass spectrometry revealed site‐specific acetylation of histones H2A, H2A.V, and H4, uncovering distinct acetylation rates and patterns across individual lysines.

Three-dimensional collagen I promotes gemcitabine resistance in vitro in pancreatic cancer cells through HMGA2-dependent histone acetyltransferase expression. [PDF]

PLoS ONE, 2013
Pancreatic ductal adenocarcinoma (PDAC) is associated with a pronounced collagen-rich stromal reaction that has been shown to contribute to chemo-resistance.

Interaction of the HPV E7 proteins with the pCAF acetyltransferase [PDF]

Oncogene, 2003
Most cervical carcinomas express the E6 and E7 proteins of a high-risk human papillomavirus (HPV). These proteins affect growth control by interfering with the functions of cell regulatory proteins, promoting oncogenic transformation. A key target of E7 is the tumor suppressor protein pRb, which directly interacts with E7.

Selective targeting of cortactin tandem repeat acetylation by human lysine deacetylases

The FEBS Journal, EarlyView.
Cortactin function is regulated by acetylation at several lysine residues within its tandem repeat region. Using genetic code expansion to generate cortactin variants containing precisely defined acetylation marks, we show that HDAC6 is the primary enzyme removing these modifications, with SIRT1 and SIRT2 also acting at selected sites but with lower ...
