|December 21, 2007
Summary
This study identified abundant and tissue-specific prostate transcripts, including androgen-regulated genes (ARGs). Some ARGs, like HSPA5 and MAT2A, show potential as therapeutic targets for prostate cancer treatment.
Area of Science:
- Genomics
- Molecular Biology
- Oncology
Background:
- The prostate is an androgen-dependent tissue.
- Understanding prostate-specific gene expression is crucial for its function and disease.
Purpose of the Study:
- To identify abundant and tissue-specific transcripts in the mouse prostate.
- To investigate androgen-responsive genes (ARGs) specifically regulated in the prostate.
- To explore the role of prostate-specific ARGs in human prostate cancer cell growth.
Main Methods:
- Serial analysis of gene expression (SAGE) was used to sequence 4,294,186 tags from normal mouse tissues.
- Transcriptomes of 14 different mouse tissues were analyzed.
- Small interference RNA (siRNA) was used in LNCaP cells to validate gene functions.
Main Results:
- Abundant transcripts were linked to prostatic secretion, energy metabolism, and immunity.
- Many known prostate-specific transcripts involved in secretion, polyamine transport, and immunity were confirmed.
- Only 22 of 114 ARGs in the prostate were modulated by dihydrotestosterone (DHT) across multiple tissues.
- Inhibition of HSPA5 and MAT2A via siRNA repressed human prostate cancer LNCaP cell growth.
Conclusions:
- The study globally assessed the prostate transcriptome, identifying key abundant and tissue-specific transcripts.
- Prostate-specific ARGs were revealed, highlighting their role in unique organ functions.
- These identified ARGs present potential targets for novel gene-based therapies for prostate cancer prevention and treatment.

01:26Testosterone: Functions and Regulation
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
02:14GTPases and their Regulation
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒ small G-proteins consisting of a single domain and large multi-domain G-proteins.

02:23Master Transcription Regulators
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...
01:22Activation and Inactivation of G Proteins
Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high affinity and are together...
