Sterol Regulatory Element-Binding Protein 2 (SREBP-2)
SREBP-2 is a key transcription factor that primarily regulates cholesterol biosynthesis and uptake. In recent years, its dysregulation has been linked to altered lipid metabolism within tumors, potentially affecting tumor growth, metastasis, and response to treatment.
– SREBP-2) is a pivotal transcriptional factor in cholesterol metabolism.
– SREBP-2 controls the transcription of genes involved in cholesterol biosynthesis and uptake (e.g., HMG-CoA reductase, LDL receptor).
– Cancer cells may upregulate SREBP-2 as part of metabolic rewiring to meet the demands of rapid proliferation.
– Elevated SREBP-2 expression has been observed in several tumor types, including prostate, breast, and hepatocellular carcinoma.
– High expression levels are sometimes associated with aggressive tumor phenotypes, increased proliferative capacity, and a higher incidence of metastasis.
• SREBP-2 plays a critical role in maintaining lipid homeostasis, and its dysregulation in cancer can contribute to tumor growth and aggressiveness.
• Elevated SREBP-2 expression is generally associated with enhanced tumor cell proliferation, increased risk of metastasis, and in some instances, a poorer prognosis.
