Dynamic regulation of RNF168-mediated ubiquitylation of histone H2A Lys13,15 (H2AK13,15ub) at DNA double-strand breaks (DSBs) is crucial for preventing aberrant DNA repair and maintaining genome stability. However, it remains unclear which deubiquitylating enzyme (DUB) removes H2AK13,15ub. Here we show that USP51, a previously uncharacterized DUB, deubiquitylates H2AK13,15ub and regulates DNA d...

Breast cancer is one of the leading causes of cancer death among women in the United States. Patients expressing the estrogen and progesterone receptor (ER and PR) and human epidermal growth factor 2 (HER-2) tumor markers have favorable prognosis and efficacious therapeutic options. In contrast, tumors that are negative for these markers (triple-negative) have a disproportionate share of morbid...

Virus infection triggers interferon (IFN)-mediated innate immune defenses in part through viral nucleic acid interactions. However, the immune recognition mechanisms by which the host identifies incoming DNA viruses are still elusive. Here, we show that increased levels of Kaposi's sarcoma-associated herpesvirus (KSHV) persistency are observed in retinoic acid-inducible gene I (RIG-I)-deficient...

Dysfunctional uterine bleeding (DUB) is a common presentation in the emergency department and has a wide differential. Most presentations of DUB are in hemodynamically stable patients and can be evaluated as an outpatient. Uterine arteriovenous malformation (AVM) is one presentation that can result in a life-threatening medical emergency with unexpected sudden and massive vaginal bleeding. We d...

BHD: Birt-Hogg-Dub e syndrome FLCN: folliculin mTOR: mammalian target of rapamycin TS: tuberous sclerosis complex B irt-Hogg-Dub e syndrome (BHD) is an uncommon autosomal dominant genodermatosis characterized by fibrofolliculomas and trichodiscomas on the face and neck with acrochordons in flexural areas. These skin signs serve as markers for internal disease, most importantly spontaneous pneum...

Maintaining control over inflammatory processes represents a paradox for viral pathogens. Although many viruses induce host inflammatory responses to facilitate infection, control is necessary to avoid overactivation. One way is through the manipulation of proinflammatory chemokine levels, both host and viral. Murine cytomegalovirus (MCMV), a model betaherpesvirus, encodes a viral C-C chemokine...
