Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

DNA in Uninfected and Virus-Infected Cells Complementary to Avian Tumor Virus RNA [PDF]

Proceedings of the National Academy of Sciences, 1971
The 70S RNA component of several avian tumor viruses was hybridized with DNA extracted from avian tumor virus-infected and uninfected chicken and Japanese quail cells. Tritium-labeled 70S RNAs from Rous sarcoma virus (RSV), Rous associated virus-1 (RAV-1), RAV-60, and Schmidt-Ruppin-RSV (SR-RSV) hybridize from 3 to 10 times more with DNA ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

hnRNPA2B1 recognizes RNA virus SFTSV infection through mitochondrial DNA

mBio
The heterogeneous nuclear ribonucleoprotein (hnRNPA2B1, hereafter A2B1) was identified as a novel nuclear DNA sensor that mediates antiviral immunity by recognizing viral DNA in the nucleus. However, it remains largely unclear whether A2B1 could function

Mycoviruses as Triggers and Targets of RNA Silencing in White Mold Fungus Sclerotinia sclerotiorum

Viruses, 2018
This study aimed to demonstrate the existence of antiviral RNA silencing mechanisms in Sclerotinia sclerotiorum by infecting wild-type and RNA-silencing-deficient strains of the fungus with an RNA virus and a DNA virus.

SEN virus genotype H distribution in β-thalassemic patients and in healthy donors in Iraq: Molecular and physiological study.

PLoS Neglected Tropical Diseases, 2020
The SEN virus (SENV) has been linked to transfusion-associated non-A-E hepatitis; however, information regarding SENV infections in patients with thalassemia, particularly in those with hepatitis virus co-infections, remains limited.

Relationship Between Non-Hodgkin's Lymphoma and Blood Levels of Epstein-Barr Virus in Children in North-Western Tanzania: A Case Control Study. [PDF]

, 2013
Non-Hodgkin's Lymphomas (NHL) are common in African children, with endemic Burkitt's lymphoma (BL) being the most common subtype. While the role of Epstein-Barr Virus (EBV) in endemic BL is known, no data are available about clinical presentations of NHL

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein

FEBS Open Bio, EarlyView.
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Acute Infection and Subsequent Subclinical Reactivation of Herpes Simplex Virus 2 after Vaginal Inoculation of Rhesus Macaques. [PDF]

, 2019
Herpes simplex virus 2 (HSV-2) is a common sexually transmitted infection with a highly variable clinical course. Many infections quickly become subclinical, with episodes of spontaneous virus reactivation.

Frequent detection of high human papillomavirus DNA loads in oral potentially malignant disorders [PDF]

, 2016
Human papillomavirus (HPV) is estimated to be the cause of 40-80% of the squamous cell carcinoma of the oropharynx but only of a small fraction of the oral cavity cancers.
