RPL6 Interacts with HMGCS1 to Stabilize HIF‐1α by Promoting Cholesterol Production in Hepatocellular Carcinoma

Advanced Science, EarlyView.
The study found that RPL6 is frequently upregulated in HCC tissues with extrahepatic metastasis. Elevated RPL6 bound to and increased the stability of HMGCS1 mRNA, thereby enhancing intracellular cholesterol levels. Subsequently, increased cholesterol promotes cancer metastasis in HCC by stabilizing HIF‐1α protein.

Regulation of vertebrate liver HMG-CoA reductase via reversible modulation of its catalytic activity

Journal of Lipid Research, 1980
We have investigated the comparative biochemistry of in vitro regulation of HMG-CoA reductase (EC 1.1.1.34) in microsomal preparations from the livers of nine vertebrates.

Responsive ROS‐Augmented Prodrug Hybridization Nanoassemblies for Multidimensionally Synergitic Treatment of Hepatocellular Carcinoma in Cascade Assaults

Advanced Science, EarlyView.
This study proposes a novel HCC therapy using CA‐4S2@ES‐Cu nanomedicines to amplify cuproptosis, enhancing chemotherapy and immunotherapy. CA‐4 and ES‐Cu synergistically inhibit tumor growth, induce immune responses, and reverse the immunosuppressive microenvironment, offering an effective multidimensional therapeutic strategy for HCC treatment ...

Hydrogen‐Producing Catalysts Based on Ferredoxin Scaffolds

Advanced Science, EarlyView.
Selected plant‐type ferredoxins that lack their natural [2Fe‐2S] clusters functionally bind a hydrogenase active site cofactor and act as hydrogenases themselves. In combination with photosystem I, the light‐dependent H₂ evolution almost matches the H₂ production rates of the natural system.

Activation of HMG-CoA reductase by microsomal phosphatase

Journal of Lipid Research, 1983
HMG-CoA reductase activity can be modulated by a reversible phosphorylation-dephosphorylation with the phosphorylated form of the enzyme being inactive and the dephosphorylated form, active. Phosphatases from diverse sources, including cytosol, have been

Nanomedicine‐Driven Modulation of Reductive Stress for Cancer Therapy

Advanced Science, EarlyView.
This article introduces a novel therapeutic paradigm that deliberately induces reductive stress within tumor cells to exploit their unique biochemical vulnerabilities. It systematically reviews the underlying biological mechanisms, current detection and monitoring techniques, and emerging advanced nanotechnology platforms specifically designed to ...

Regulation of hydroxymethylglutaryl-CoA reductase in rat leukocytes

Journal of Lipid Research, 1977
Methods were developed for the assay of hydroxymethylglutaryl-CoA reductase (NADPH) activity in microsomes from rat leukocytes. The activity in freshly isolated leukocytes is low compared to rat liver but can be assayed reliably. The patterns of response

Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer

Advanced Science, EarlyView.
Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

Partial purification from rat liver microsomes of three native protein phosphatases with activity towards HMG-CoA reductase.

Journal of Lipid Research, 1984
A procedure for the isolation and partial purification of three hydroxymethylglutaryl coenzyme A reductase phosphatases in their native high molecular weight form from rat liver microsomes is described for the first time.
