Summary

This summary is machine-generated.

Mortalin, an oncogene, drives prostate cancer (PC) progression and metastasis by regulating tumor cell migration and invasion. Targeting Mortalin presents a promising new strategy for treating advanced, hormone-resistant prostate cancer.

Area Of Science

  • Oncology
  • Molecular Biology
  • Cancer Research

Background

  • Prostate cancer (PC) is a significant global health issue.
  • Androgen-independent PC progresses slowly and lacks effective treatments.
  • Mortalin, an oncogene, is implicated in tumor migration and invasion.

Purpose Of The Study

  • To investigate the role of Mortalin in prostate cancer progression.
  • To explore Mortalin as a potential therapeutic target for PC.

Main Methods

  • In-vivo and in-vitro studies were conducted.
  • Mortalin expression levels in PC tissues were analyzed.
  • The Wnt/β-catenin signaling pathway's role was examined.

Main Results

  • Mortalin expression is upregulated in prostate cancer tissues.
  • Mortalin promotes PC proliferation and metastasis.
  • Mortalin regulates the epithelial-mesenchymal transition (EMT) via Wnt/β-catenin signaling.

Conclusions

  • Mortalin plays a crucial role in prostate cancer progression and metastasis.
  • Mortalin is a potential immunotherapeutic target for prostate cancer.
  • Targeting Mortalin may overcome hormone resistance in PC.

Canonical Wnt Signaling Pathway 02:54

8.7K

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Catenins 01:23

2.3K

Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the...

mTOR Signaling and Cancer Progression 03:03

3.8K

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.
The mTOR pathway or the...

PI3K/mTOR/AKT Signaling Pathway 01:22

3.5K

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

The Intrinsic Apoptotic Pathway 01:31

6.5K

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
