1. SREBP Transcription Factors

Therapeutic Strategies Targeting SREBP Transcription Factors: An Update to 2024

• Key Details: Sterol regulatory element-binding proteins (SREBPs) are transcription factors critical for lipid metabolism, regulating cholesterol, fatty acid, and triglyceride synthesis. They are implicated in metabolic diseases (e.g., type 2 diabetes, non-alcoholic fatty liver disease, atherosclerosis) and cancers, particularly gastrointestinal malignancies and hepatocellular carcinoma (HCC). Recent research highlights:
• SREBP-1 and SREBP-2 regulate distinct pathways: SREBP-1 (isoforms 1a and 1c) drives fatty acid synthesis, while SREBP-2 focuses on cholesterol synthesis. SREBP-1a is highly expressed in specific tissues like the intestine and heart, while SREBP-1c is insulin-responsive and predominant in the liver.
• In HCC, SREBP-1 is regulated by the PI3K-Akt-mTOR axis, epigenetic modifications (e.g., methylation by PRMT5, neddylation by UBC12), and transcription factors like LXR and PPARs, promoting lipogenesis and tumor progression.

• In gastrointestinal cancers, SREBPs integrate dietary and carcinogenic signals, with subtype-specific mechanisms driving malignant phenotypes. For example, SREBP-1a methylation at arginine-321 enhances HCC cell proliferation.
• COVID-19 patients show elevated SREBP-2 C-terminal fragments in blood, linked to cytokine storms and reduced cholesterol biosynthesis, suggesting a severity biomarker.
• Therapeutic Strategies:
• Small molecule inhibitors like fatostatin block SREBP cleavage, reducing lipid synthesis in cancers.
• Natural compounds (e.g., berberine) modulate AMPK/mTOR pathways to inhibit SREBP activity.
• Statins inhibit the mevalonic acid pathway, indirectly affecting SREBP-2 in cancer and metabolic diseases.
• Betulin reduces atherosclerotic plaque size by inhibiting SREBP, showing promise for metabolic disorders.
• Antiviral potential: AM580, a retinoid derivative, inhibits SREBP-mediated lipid pathways, disrupting viral replication (e.g., MERS-CoV, influenza A).
• Updates to 2024: A comprehensive review (July 2024) analyzed SREBP subtypes (1a, 1c, 2) in gastrointestinal tumors, emphasizing targeted inhibitors and their potential in cancer therapy. SREBP-2’s role in COVID-19 severity and NF-κB inhibition (e.g., SN50) to suppress cytokine storms are emerging areas.
