E2A selectively regulates TGF‐β–induced apoptosis in KRAS‐mutant non‐small cell lung cancer

Molecular Oncology, EarlyView.
Ability to induce apoptosis by TGF‐β is frequently lost in advanced lung adenocarcinoma despite intact TGF‐β signaling. We identify E2A as a mutant KRAS–dependent mediator of resistance to TGF‐β–induced apoptosis. TGF‐β induces E2A via SMAD3 in mutant KRAS cells, and E2A silencing restores apoptosis and enhances radiation response in cell lines ...

The Primate Lentivirus-Encoded Nef Protein Can Regulate Several Steps of the Viral Replication Cycle

Virology, 1999
The primate lentiviruses encode a protein, Nef, which is required for efficient viral replication in their host. Several biological activities of nef identified in vitro may contribute to this requirement in vivo, including receptor modulation and interference with cellular signaling pathways.

HIV-1 envelope proteins up-regulate N6-methyladenosine levels of cellular RNA independently of viral replication [PDF]

Journal of Biological Chemistry, 2019
N6-methyladenosine (m6A) modification of HIV-1 RNA regulates viral replication and protein expression. The m6A modification is regulated by two groups of cellular proteins named writers and erasers that add or remove m6A, respectively. HIV-1 infection of CD4+ T-cells increases m6A levels of cellular mRNA, but the underlying mechanism is unknown.

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Cullin 3-mediated ubiquitination restricts enterovirus D68 replication and is counteracted by viral protease 3C

Journal of Virology
Enterovirus D68 (EV-D68) has emerged as a significant threat to public health because of its association with respiratory illnesses and neurological complications, including acute flaccid myelitis.

The Role of Electron Microscopy in Studying the Continuum of Changes in Membranous Structures during Poliovirus Infection

Viruses, 2015
Replication of the poliovirus genome is localized to cytoplasmic replication factories that are fashioned out of a mixture of viral proteins, scavenged cellular components, and new components that are synthesized within the cell due to viral manipulation/

Cellular hnRNP A2/B1 interacts with the NP of influenza A virus and impacts viral replication. [PDF]

PLoS ONE, 2017
The viral ribonucleoprotein (vRNP) of influenza A virus is formed by virion RNA (vRNA), viral polymerase complex, and nucleoprotein (NP). The NP plays an important role in facilitating the replication and stabilization of viral RNA.

Regulation of apoptosis and replicative senescence in CD8+ T cells from patients with viral infections

Biochemical Society Transactions, 2000
Activated T lymphocytes are generated during an immune response. The induction of T lymphocyte proliferation is one way in which cell numbers can be controlled. However, once generated, the increased numbers of cells must be removed in order to re-establish cellular homoeostasis within the immune system.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

An invertebrate Warburg effect: a shrimp virus achieves successful replication by altering the host metabolome via the PI3K-Akt-mTOR pathway.

PLoS Pathogens, 2014
In this study, we used a systems biology approach to investigate changes in the proteome and metabolome of shrimp hemocytes infected by the invertebrate virus WSSV (white spot syndrome virus) at the viral genome replication stage (12 hpi) and the late ...
