The Sequential Mechanism of HIV Reverse Transcriptase RNase H [PDF]

open access: yesJournal of Biological Chemistry, 2000
Synthesis of the minus strand of viral DNA by human immunodeficiency virus, type 1 (HIV-1) reverse transcriptase is accompanied by RNase H degradation of the viral RNA genome. RNA fragments remain after synthesis and are degraded by the polymerase-independent mode of RNase H cleavage.

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

open access: yesMolecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Protein folding in the modern era: a pedestrian's guide [PDF]

open access: yesarXiv, 2020
The prediction of protein secondary and tertiary structures from the primary amino acid sequence is both an incredibly important and incredibly difficult problem. Accurate prediction of a protein's native structure can provide critical insights about its function, ultimately leading to breakthoughs in drug design and disease diagnosis.

Characterization of Nucleoside Reverse Transcriptase Inhibitor-Associated Mutations in the RNase H Region of HIV-1 Subtype C Infected Individuals

open access: yesViruses, 2017
The South African national treatment programme includes nucleoside reverse transcriptase inhibitors (NRTIs) in both first and second line highly active antiretroviral therapy regimens.

Conservation patterns of HIV-1 RT connection and RNase H domains: identification of new mutations in NRTI-treated patients. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: Although extensive HIV drug resistance information is available for the first 400 amino acids of its reverse transcriptase, the impact of antiretroviral treatment in C-terminal domains of Pol (thumb, connection and RNase H) is poorly ...

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Partitioning of a graph into induced subgraphs not containing prescribed cliques [PDF]

open access: yesarXiv, 2022
Let $K_p$ be a complete graph of order $p\geq 2$. A $K_p$-free $k$-coloring of a graph $H$ is a partition of $V(H)$ into $V_1, V_2\ldots,V_k$ such that $H[V_i]$ does not contain $K_p$ for each $i\leq k $. In 1977 Borodin and Kostochka conjectured that any graph $H$ with maximum degree $\Delta(H)\geq 9$ and without $K_{\Delta(H)}$ as a subgraph has ...

RNase H and replication of ColE1 DNA in Escherichia coli [PDF]

open access: yesJournal of Bacteriology, 1986
Amber mutations within the rnh (RNase H) gene of Escherichia coli K-12 were isolated by selecting for bacteria capable of replicating in a sup+ background replication-defective cer-6 mutant of the ColE1 replicon. The cer-6 mutation is an alteration of one base pair located 160 nucleotides upstream of the unique replication origin of this plasmid ...

The anticancer effect of the HDAC inhibitor belinostat is enhanced by inhibitors of Bcl‐xL or Mcl‐1 in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
The pan‐HDAC inhibitor belinostat increases the expression of the pro‐apoptotic proteins Bim, Puma, and Noxa and induces apoptosis in ovarian cancer cell lines and patient‐derived tumor organoids when used at high concentrations. Moreover, inhibiting the anti‐apoptotic proteins Bcl‐xL or Mcl‐1 sensitizes these preclinical models to the cytotoxic effect

On generalized list $\G$-free colorings of graphs [PDF]

open access: yesarXiv, 2022
For given graph $H$ and graphical property $P$, the conditional chromatic number $\chi(H,P)$ of $H$, is the smallest number $k$, so that $V(H)$ can be decomposed into sets $V_1,V_2,\ldots, V_k$, in which $H[V_i]$ satisfies the property $P$, for each $1\leq i\leq k$.
