Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS 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.

In Vivo Characterization of Linc-p21 Reveals Functional cis-Regulatory DNA Elements

open access: yesCell Reports, 2016
The Linc-p21 locus, encoding a long non-coding RNA, plays an important role in p53 signaling, cell-cycle regulation, and tumor suppression. However, despite extensive study, confusion exists regarding its mechanism of action: is activity driven by the ...

The lncRNA HOTAIR transcription is controlled by HNF4α-induced chromatin topology modulation [PDF]

open access: yes, 2018
The expression of the long noncoding RNA HOTAIR (HOX Transcript Antisense Intergenic RNA) is largely deregulated in epithelial cancers and positively correlates with poor prognosis and progression of hepatocellular carcinoma and gastrointestinal cancers.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

The RNA Polymerase II Factor RPAP1 Is Critical for Mediator-Driven Transcription and Cell Identity

open access: yesCell Reports, 2018
Summary: The RNA polymerase II-associated protein 1 (RPAP1) is conserved across metazoa and required for stem cell differentiation in plants; however, very little is known about its mechanism of action or its role in mammalian cells. Here, we report that

Epigenetic regulation of IFITM1 expression in lipopolysaccharide-stimulated human mesenchymal stromal cells

open access: yesStem Cell Research & Therapy, 2020
Background Toll-like receptor 4 (TLR4) ligands such as lipopolysaccharide (LPS) activate immunomodulatory functions and the migration of human mesenchymal stromal cells (hMSCs). Here, we study the migration-related gene expression of LPS-stimulated hMSCs

The enhancer RNA ARIEL activates the oncogenic transcriptional program in T-cell acute lymphoblastic leukemia.

open access: yesBlood, 2019
The oncogenic transcription factor TAL1 regulates the transcriptional program in T-cell acute lymphoblastic leukemia (T-ALL). ARID5B is one of critical downstream targets of TAL1 which further activates the oncogenic regulatory circuit in T-ALL cells ...

Elongin A associates with actively transcribed genes and modulates enhancer RNA levels with limited impact on transcription elongation rate in vivo

open access: yesJournal of Biological Chemistry, 2020
Elongin A (EloA) is an essential transcription factor that stimulates the rate of RNA polymerase II (Pol II) transcription elongation in vitro. However, its role as a transcription factor in vivo has remained underexplored.

Integrator mediates the biogenesis of enhancer RNAs [PDF]

open access: yesNature, 2015
Integrator is a multi-subunit complex stably associated with the carboxy-terminal domain (CTD) of RNA polymerase II (RNAPII). Integrator is endowed with a core catalytic RNA endonuclease activity, which is required for the 3'-end processing of non-polyadenylated, RNAPII-dependent, uridylate-rich, small nuclear RNA genes. Here we examine the requirement
