Summary
Curcumin impacts prostate cancer cell gene expression, affecting growth and stress pathways. It downregulates key oncogenes like TMPRSS2-ERG and growth factor receptors, offering potential therapeutic insights.
Area of Science:
- Molecular biology
- Cancer research
- Pharmacology
Background:
- Curcumin, derived from turmeric, shows anti-cancer potential.
- Prostate cancer research is exploring novel chemopreventive agents.
- Understanding curcumin's molecular mechanisms in prostate cancer is crucial.
Purpose of the Study:
- To investigate curcumin's effect on gene expression in prostate cancer cells.
- To identify molecular pathways regulated by curcumin.
- To compare curcumin's response in different prostate cancer cell lines.
Main Methods:
- Gene expression profiling using transcriptomics.
- Hierarchical clustering and functional classification of gene expression data.
- Analysis of Curcumin-Gene Expression Response (Cu-GER) in LNCaP and C4-2B cells.
Main Results:
- Curcumin co-regulates genes in oxidative stress and growth signaling pathways.
- Androgen-independent C4-2B cells show a weaker Cu-GER than androgen-dependent LNCaP cells.
- Curcumin downregulates TMPRSS2-ERG fusion transcript, EGFR, and ERBB2 expression.
Conclusions:
- Curcumin exhibits distinct gene expression patterns in prostate cancer cells with varying phenotypes.
- Novel gene networks regulated by curcumin provide insights into its anti-cancer mechanisms.
- Cu-GER may serve as a biomarker for curcumin's efficacy in prostate cancer treatment.

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
