Pericytes change function depending on glioblastoma vicinity: emphasis on immune regulation
Molecular Oncology, EarlyView.Pericytes alter their transcriptome depending on their proximity to the tumor core. In the tumor core, pericytes display a more active state with higher communication strength but with lower immune activation potential and a shift toward extracellular matrix production.

Mycoviruses, RNA Silencing, and Viral RNA Recombination [PDF]
, 2011 In contrast to viruses of plants and animals, viruses of fungi, mycoviruses, uniformly lack an extracellular phase to their replication cycle. The persistent, intracellular nature of the mycovirus life cycle presents technical challenges to experimental design. However, these properties, coupled with the relative simplicity and evolutionary position of

Molecular Oncology, EarlyView.RKIP, a metastasis suppressor protein, modulates key oncogenic pathways in lung adenocarcinoma. In silico analyses linked low RKIP expression to poor survival. Functional studies revealed RKIP overexpression reduces tumor aggressiveness and enhances sensitivity to EGFR‐targeted therapies, while its loss promotes resistance.

Replicon RNA Viral Vectors as Vaccines [PDF]
Vaccines, 2016 Single-stranded RNA viruses of both positive and negative polarity have been used as vectors for vaccine development. In this context, alphaviruses, flaviviruses, measles virus and rhabdoviruses have been engineered for expression of surface protein genes and antigens.

Molecular Oncology, EarlyView.Loss‐of‐function mutations in the scaffold subunit of protein phosphatase 2A (PP2A), PPP2R1A, sensitize ovarian clear cell carcinoma to immune checkpoint blockade (ICB) by enhancing the interferon gamma response and promoting antitumor immune cell infiltration.

Viral and cellular messenger RNA targets of viral microRNAs [PDF]
Nature, 2009 Given the propensity of viruses to co-opt cellular pathways and activities for their benefit, it is perhaps not surprising that several viruses have now been shown to reshape the cellular environment by reprogramming the host's RNA-interference machinery. In particular, microRNAs are produced by the various members of the herpesvirus family during both

Possible role of human ribonuclease dicer in the regulation of R loops
FEBS Open Bio, EarlyView.R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

FEBS Open Bio, EarlyView.Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

Live Cell Imaging Reveals the Relocation of dsRNA Binding Proteins Upon Viral Infection
Molecular Plant-Microbe Interactions, 2017 Viral infection triggers a range of plant responses such as the activation of the RNA interference (RNAi) pathway. The double-stranded RNA binding (DRB) proteins DRB3 and DRB4 are part of this pathway and aid in defending against DNA and RNA viruses ...

FEBS Open Bio, EarlyView.In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.
