Viruses, 2021 Development of potential HIV-1 curative interventions requires accurate characterization of the proviral reservoir, defined as host-integrated viral DNA genomes that drive rebound of viremia upon halting ART (antiretroviral therapy).

The Role of Capsid in HIV-1 Nuclear Entry
Viruses, 2021 HIV-1 can infect non-dividing cells. The nuclear envelope therefore represents a barrier that HIV-1 must traverse in order to gain access to the host cell chromatin for integration.

Viruses, 2021 Antiretroviral therapy (ART) effectively reduces cycles of viral replication but does not target proviral populations in cells that persist for prolonged periods and that can undergo clonal expansion.

Viruses, 2021 The 3C-like protease (3CLpro) of SARS-CoV-2 is considered an excellent target for COVID-19 antiviral drug development because it is essential for viral replication and has a cleavage specificity distinct from human proteases.

mBio, 2021 Human immunodeficiency virus type 1 (HIV-1) Gag selects and packages the HIV RNA genome during virus assembly. However, HIV-1 RNA constitutes only a small fraction of the cellular RNA.

MTBP phosphorylation controls DNA replication origin firing
Scientific Reports, 2021 Faithful genome duplication requires regulation of origin firing to determine loci, timing and efficiency of replisome generation. Established kinase targets for eukaryotic origin firing regulation are the Mcm2-7 helicase, Sld3/Treslin/TICRR and Sld2 ...

Reversal of terminal differentiation and control of DNA replication [PDF]
, 1993 DNA replication in mammalian cells occurs in discrete nuclear foci. Here we show that terminally differentiated myotubes can be induced to reenter S phase and show the same pattern of replication foci as cycling cells.

The mechanism of replication stalling and recovery within repetitive DNA
Nature Communications, 2022 DNA replication of repetitive sequences was recreated in a test tube using purified components. DNA alone was sufficient to induce stalling. Both stalling and recovery were dictated by the capacity of DNA to fold into unusual secondary structures.

The Swr1 chromatin-remodeling complex prevents genome instability induced by replication fork progression defects. [PDF]
, 2018 Genome instability is associated with tumorigenesis. Here, we identify a role for the histone Htz1, which is deposited by the Swr1 chromatin-remodeling complex (SWR-C), in preventing genome instability in the absence of the replication fork/replication ...

Adaptation of HIV-1/HIV-2 Chimeras with Defects in Genome Packaging and Viral Replication
mBio, 2022 Frequent recombination is a hallmark of retrovirus replication. In rare cases, recombination occurs between distantly related retroviruses, generating novel viruses that may significantly impact viral evolution and public health.
