Interaction of Geminivirus Rep Protein with Replication Factor C and Its Potential Role during Geminivirus DNA Replication

Virology, 2002
Geminivirus DNA replication during the rolling-circle stage depends on the use of a DNA primer, a strategy poorly understood as compared with other eukaryotic viral systems that rely on RNA or protein as primers. Here we have used wheat dwarf virus (WDV) with the aim of elucidating the events leading to recruitment of cell factors at the replication ...

Replication-Competent Recombinant Vesicular Stomatitis Virus Encoding Hepatitis C Virus Envelope Proteins [PDF]

Journal of Virology, 2007
ABSTRACT Although in vitro replication of the hepatitis C virus (HCV) JFH1 clone of genotype 2a (HCVcc) has been developed, a robust cell culture system for the 1a and 1b genotypes, which are the most prevalent viruses in the world and resistant to interferon therapy, has not yet been established.

Generation of H9 T-cells stably expressing a membrane-bound form of the cytoplasmic tail of the Env-glycoprotein: lack of transcomplementation of defective HIV-1 virions encoding C-terminally truncated Env

Retrovirology, 2006
H9-T-cells do not support the replication of mutant HIV-1 encoding Env protein lacking its long cytoplasmic C-terminal domain (Env-CT). Here we describe the generation of a H9-T-cell population constitutively expressing the HIV-1 Env-CT protein domain ...

The epigenetic control of E-box and Myc-dependent chromatin modifications regulate the licensing of lamin B2 origin during cell cycle [PDF]

, 2012
Recent genome-wide mapping of the mammalian replication origins has suggested the role of transcriptional regulatory elements in origin activation. However, the nature of chromatin modifications associated with such trans-factors or epigenetic marks ...

The Nuclease Activity of the Yeast Dna2 Protein, Which Is Related to the RecB-like Nucleases, Is Essential in Vivo [PDF]

, 2000
Saccharomyces cerevisiae Dna2 protein is required for DNA replication and repair and is associated with multiple biochemical activities: DNA-dependent ATPase, DNA helicase, and DNA nuclease.

Multiple effects of silymarin on the hepatitis C virus lifecycle [PDF]

, 2010
Silymarin, an extract from milk thistle (Silybum marianum), and its purified flavonolignans have been recently shown to inhibit hepatitis C virus (HCV) infection, both in vitro and in vivo.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Real-time imaging of Leishmania mexicana-infected early phagosomes: a study using primary macrophages generated from green fluorescent protein-Rab5 transgenic mice [PDF]

, 2009
The small GTPase Rab5 is a key regulator of endosome/phagosome maturation and in intravesicular infections marks a phagosome stage at which decisions over pathogen replication or destruction are integrated.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Mutations in the C-terminus of HBoV NS1 affect the function of NP1

Scientific Reports, 2017
Human bocavirus 1 (HBoV1) is an autonomous parvovirus in the Bocaparvovirus genus. The multifunctional nuclear protein NP1 is involved in viral replication.
