Abstract

Insights

FUS protein and m6A modification promote prostate adenocarcinoma (PRAD) growth by inhibiting ferroptosis. Targeting this pathway could offer new therapeutic strategies for PRAD.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Prostate adenocarcinoma (PRAD) progression is not fully understood.
  • The roles of FUS protein and mRNA modifications in PRAD are under investigation.
  • Ferroptosis is a key mechanism in cancer development.

Purpose of the Study:

  • To investigate the role of FUS/NRF2 signaling in PRAD.
  • To explore the impact of mRNA modification on ferroptosis in PRAD.
  • To identify potential therapeutic targets for PRAD.

Main Methods:

  • Bioinformatics analysis of FUS expression and m6A modification in PRAD.
  • Detection of ferroptosis, apoptosis, and autophagy markers in prostate cancer cells (CRPC).
  • Assessment of oxidative stress and NRF2/HO-1 pathway indicators.

Main Results:

  • High FUS expression in PRAD correlates with reduced patient survival.
  • FUS knockdown decreased m6A methylation, P53, and GPX4, while activating the NRF2/HO-1 pathway.
  • Reduced FUS expression promoted ferroptosis, inhibiting PRAD growth.

Conclusions:

  • FUS and m6A modification promote PRAD growth by inhibiting ferroptosis.
  • Increased m6A modification enhances FUS expression, leading to PRAD growth.
  • Targeting FUS/NRF2 signaling and m6A modification may be a therapeutic strategy for PRAD.

Abnormal 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...

mTOR Signaling and Cancer Progression03:03

mTOR 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.

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...
