The E3 ubiquitin ligase c-IAP1 regulates PCSK9-mediated LDLR degradation: Linking the TNF-α pathway to cholesterol uptake [PDF]

, 2010
Proprotein convertase subtilisin/kexin type 9 (PCSK9), in addition to LDLR (low-density lipoprotein receptor) and APOB (apolipoprotein B), is one of three loci implicated in autosomal dominant hypercholesterolaemia (ADH)^1^.

Deciphering the phylogenetic history of neuroserpin orthologs across metazoans by analysis of synteny and rare genomic characters [PDF]

, 2008
The superfamily of serine proteinase inhibitors (serpins) is involved in wide arrays of fundamental biological processes such as blood coagulation, complement activation, fibrinolysis, angiogenesis, inflammation and tumor suppression. The average protein

Abnormal expression and processing of the proprotein convertases PC1 and PC2 in human colorectal liver metastases

BMC Cancer, 2005
Background The family of proprotein convertases has been recently implicated in tumorigenesis and metastasis in animal models. However, these studies have not yet been completely corroborated in human tumors.

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Blockade of colon cancer metastasis via single and double silencing of PCSK7/PCSK9: enhanced T cells cytotoxicity in mouse and human

Journal for ImmunoTherapy of Cancer
Background Immunotherapy approaches based on T cells provided breakthroughs in cancer treatment but could cause many immune-related adverse events, and their efficacy is limited for many cancers with an acquired dysfunction/exhaustion of T cells.

Plaque‐Hepatic Targeting Nanotherapy Disrupts the PCSK9‐LOX‐1 Axis to Suppress oxLDL in Atherosclerosis

Advanced Science, EarlyView.
Self‑amplifying PCSK9–LOX‑1 feedback axis drives atherosclerotic progression by promoting oxLDL generation and endothelial uptake. A dual‑targeting nanoplatform (siPCSK9@PEAL NPs‑aL) is constructed to simultaneously silence hepatic PCSK9 for lipid lowering and block plaque LOX‑1 for anti‑inflammation.

The Role of Proprotein Convertases in Upper Airway Remodeling

Molecules and Cells, 2022
Chronic rhinosinusitis (CRS) is a multifactorial, heterogeneous disease characterized by persistent inflammation of the sinonasal mucosa and tissue remodeling, which can include basal/progenitor cell hyperplasia, goblet cell hyperplasia, squamous cell metaplasia, loss or dysfunction of ciliated cells, and increased matrix deposition.

Engineered Transformer Base Editor with Enhanced Editing Efficiency

Advanced Science, EarlyView.
A highly efficient transformer base editor system achieves robust genomic editing in a humanized mouse model. This work establishes a versatile and translatable platform, opening new avenues for precision gene therapy. ABSTRACT Canonical cytosine base editors (CBEs) achieve precise C‐to‐T conversions without inducing DNA double‐strand breaks (DSBs ...

Evaluation of adropin indices and PCSK9 in non-diabetic men with severe obstructive sleep apnea

Türk Biyokimya Dergisi
We aimed to investigate the relationship among proprotein convertase subtilisin/kexin type 9 (PCSK9), adropin levels, inflammation, and sleep variables in non-diabetic males with severe obstructive sleep apnea (OSA).

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

Advanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...
