Roles of TIF1β in Leukemic Stem Cell Through SETDB1‐Dependent and Independent Mechanisms

Cancer Science, EarlyView.
In leukemic stem cell, BCR::ABL cooperates with TIF1β to open chromatin at oncogenes and close chromatin at differentiation regulators, driving leukemic reprogramming. In TIF1β‐deficient stem cell, the loss of TIF1β inverts this balance, showing closed chromatin at oncogenes and open chromatin at differentiation regulators.

Infection of B Cell Follicle-Resident Cells by Friend Retrovirus Occurs during Acute Infection and Is Maintained during Viral Persistence

mBio, 2019
B cell follicles of the spleen and lymph nodes are immune privileged sites and serve as sanctuaries for infected CD4+ cells in HIV infection. It is assumed that CD8+ T cell responses promote the establishment of the reservoir, as B cell follicles do not ...

Small Cell Lung Cancer Establishes a Metabolic Autocrine Mechanism Through Active Extracellular ATP Transport

Cancer Science, EarlyView.
Small cell lung cancer (SCLC) actively exports ATP through PANX1 channels, triggering P2RX7‐mediated autocrine signaling and promoting tumor proliferation. Inhibition of PANX1 or P2RX7 disrupts this loop and suppresses tumor growth. ABSTRACT Small cell lung cancer (SCLC) is an aggressive malignancy with a 5‐year survival rate of less than 7%.

Imaging Retroviral RNA Genome Heterodimers Using Bimolecular Fluorescence Complementation (BiFC)

Viruses
Retroviruses are single-stranded RNA viruses that package two copies of their positively stranded RNA genomes as a non-covalent dimer into newly formed virions.

Making a virtue of necessity: the pleiotropic role of human endogenous retroviruses in cancer

Philosophical Transactions of the Royal Society B: Biological Sciences, 2017
Like all other mammals, humans harbour an astonishing number of endogenous retroviruses (ERVs), as well as other retroelements, embedded in their genome.

SARS‐CoV‐2 nucleocapsid protein variants have differential RNA chaperone activity

The FEBS Journal, EarlyView.
The SARS‐CoV‐2 nucleocapsid (N) protein facilitates RNA annealing through its RBD–IDR2–CTD region, identifying it as a functional RNA chaperone. The Omicron BA.5 variant shows reduced chaperone activity compared to the Wuhan wild‐type protein. Although phosphorylation has no effect on wild‐type N, phosphomimetic modification of BA.5 N restores its RNA ...

How Active Are Porcine Endogenous Retroviruses (PERVs)?

Viruses, 2016
Porcine endogenous retroviruses (PERVs) represent a risk factor if porcine cells, tissues, or organs were to be transplanted into human recipients to alleviate the shortage of human transplants; a procedure called xenotransplantation.

Endogenous Retroviruses: With Us and against Us

Frontiers in Chemistry, 2017
Mammalian genomes are scattered with thousands of copies of endogenous retroviruses (ERVs), mobile genetic elements that are relics of ancient retroviral infections. After inserting copies into the germ line of a host, most ERVs accumulate mutations that

Mycobacterium avium Subsp. paratuberculosis and Human Endogenous Retrovirus in Italian Patients With Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)

Immunology, EarlyView.
Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a recognised gastrointestinal disorder. Mycobacterium avium subspecies paratuberculosis (MAP) is implicated in IBD pathogenesis. Persistent exposure and active infections by MAP may contribute to the unsilencing of human endogenous retroviruses (HERV ...
