Abstract

Insights

Overexpression of MAGI2-AS3, a long noncoding RNA, inhibits bladder cancer progression by regulating the MAGI2/PTEN pathway. This finding offers new insights into bladder cancer mechanisms.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Long noncoding RNAs (lncRNAs) play crucial roles in regulating tumor development.
  • Understanding specific lncRNAs involved in bladder cancer (Bca) progression is essential.

Purpose of the Study:

  • To investigate the role of the lncRNA MAGI2-AS3 and the PTEN gene in bladder cancer progression.
  • To elucidate the functional relationship between MAGI2-AS3 and the MAGI2/PTEN pathway in Bca.

Main Methods:

  • Analysis of MAGI2-AS3 expression in 80 Bca tissues and paired adjacent tissues.
  • In vitro assays (transfection, cell migration, invasion) in Bca cell lines.
  • In vivo orthotopic mouse model for Bca studies.

Main Results:

  • MAGI2-AS3 was significantly downregulated in Bca tissues and correlated with poorer prognosis.
  • MAGI2-AS3 overexpression increased MAGI2 and PTEN expression in Bca cells.
  • MAGI2-AS3 overexpression inhibited Bca cell migration and invasion, partly via the MAGI2/PTEN axis.

Conclusions:

  • MAGI2-AS3 overexpression suppresses bladder cancer progression.
  • The MAGI2/PTEN pathway is a key mechanism regulated by MAGI2-AS3 in Bca.
  • MAGI2-AS3 represents a potential therapeutic target for bladder cancer.

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

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...

Abnormal Proliferation02:23

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...

Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

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...

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.
The mTOR pathway or the...
