HC-Pro inhibits HEN1 methyltransferase activity, leading to autophagic degradation of AGO1.

Helper-component proteinase (HC-Pro), encoded by potyviruses, function as viral suppressors of RNA silencing (VSRs). Despite their conserved role, HC-Pros share approximately 40% similarity, implying potential differences in VSR efficiency, particularly in their ability to inhibit HEN1 methyltransferase activity. This study investigated the inhibitory potential of HC-Pros from different potyviruses in transgenic plants.

PCSK9 Enhances Cardiac Fibrogenesis via the Activation of Toll-like Receptor and NLRP3 Inflammasome Signaling.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) has emerged as a novel target for reducing low-density lipoprotein cholesterol. PCSK9 activates the atherosclerosis process through pro-inflammation signaling. Furthermore, the serum level of PCSK9 is positively correlated with mortality in patients with heart failure (HF).

Disclaimer: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

Desmosome and Hemidesmosome Release via Exosomes from Retinal Pigmented Epithelium - A Precursor to Epithelial-Mesenchymal Transition in Early AMD?

Purpose: This minireview discusses desmosome and hemidesmosome disassembly and/or internalization and subsequent release exosomes in retinal pigmented epithelium (RPE) under oxidative stress conditions, and whether it may be a precursor to epithelial-mesenchymal transition in early Age-related Macular Degeneration (AMD).

Methods: Literature review and discussion of novel findings relevant to the focus of the review.

Results: The RPE forms the outer blood-retinal barrier, and like other epithelia it has several different types of cell-cell junctions, such as desmosomes.

Targeting the Immune Microenvironment in Chronic Lymphocytic Leukemia: An Evolving Therapeutic Strategy.

Although small molecule inhibitors that target the aberrant signaling pathways and molecular defects of chronic lymphocytic leukemia (CLL) result in improved survival benefits vs. traditional chemoimmunotherapy or chemotherapy, treatment resistance may result later, reflecting the intrinsic tumor heterogeneity, persistence of the leukemic clone, and presence of the tumor microenvironment, which supports the survival of the disease clone. Patients with CLL have immune-related abnormalities in T lymphocyte subset composition, immune synapse formation, and other immune dysregulations.
