Insights

Prostate cancer can resist hormone therapy by producing its own steroids. Insulin-like growth factor 2 (IGF2) activates this steroidogenesis pathway, driving tumor growth and treatment resistance.

Area of Science:

  • Endocrinology
  • Molecular Oncology
  • Cancer Biology

Background:

  • Prostate cancer often relies on androgen hormones for growth.
  • Hormone therapy is a standard treatment, but resistance develops.
  • De novo steroidogenesis is increasingly recognized in treatment-resistant prostate cancer.

Purpose of the Study:

  • To elucidate the molecular mechanisms of hormone therapy evasion in prostate cancer.
  • To identify novel pathways driving tumor progression and therapeutic bypass.
  • To investigate the role of Insulin-like Growth Factor 2 (IGF2) in de novo steroidogenesis.

Main Methods:

  • Analysis of molecular pathways involved in steroidogenesis.
  • Investigation of IGF2 signaling in prostate cancer cells.
  • Assessment of de novo steroidogenesis markers in tumor progression.

Main Results:

  • Lubik et al. identified a novel molecular pathway involving IGF2.
  • IGF2 was shown to activate the de novo steroidogenesis pathway.
  • This activation promotes molecular events linked to prostate cancer progression.

Conclusions:

  • De novo steroidogenesis is a key mechanism for prostate cancer to evade hormone therapy.
  • IGF2 plays a critical role in initiating this pathway.
  • Targeting the IGF2-mediated steroidogenesis pathway may offer new therapeutic strategies.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
Folliculogenesis01:20

Folliculogenesis

Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...
Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...
Intracellular Hormone Receptors01:08

Intracellular Hormone Receptors

Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell
Regulation of Metabolism01:19

Regulation of Metabolism

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...
Master Transcription Regulators02:23

Master 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...
