MicroRNAs01:22

MicroRNAs

21.1K
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

4.4K
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 Progression

3.7K
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...

Tumor Progression02:07

Tumor Progression

6.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Uterine corpus endometrial carcinoma (UCEC) is a prevalent gynecological malignancy with increasing incidence and poor prognosis.
  • Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) are key regulators of UCEC via competing endogenous RNA (ceRNA) networks.
  • N6-methyladenosine (m6A) modification is implicated in UCEC progression, but its role in m6A-associated ceRNA networks remains unclear.

Purpose of the Study:

  • To elucidate the role of m6A-associated ceRNA networks in the malignant progression of UCEC.
  • To identify specific molecular players and their interactions within these networks.
  • To explore potential diagnostic and therapeutic targets for UCEC.

Main Methods:

  • Bioinformatic analysis to construct the m6A-related ceRNA regulatory network in UCEC.
  • MeRIP assays to investigate m6A modification regulated by ALKBH5.
  • Dual-luciferase reporter assays to confirm the interaction between AC074117.1 and miR-193a-3p.
  • Cellular assays (proliferation, migration) and rescue experiments to validate the functional role of the identified axis.

Main Results:

  • The AC074117.1/miR-193a-3p axis was identified to promote UCEC malignant progression by targeting ALKBH5, an m6A demethylase.
  • MeRIP assays confirmed ALKBH5's role in regulating m6A modification in UCEC.
  • The AC074117.1/miR-193a-3p/ALKBH5 axis was shown to regulate UCEC cell proliferation and migration.
  • Functional rescue experiments demonstrated that miR-193a-3p's effects on UCEC progression are partially dependent on ALKBH5.

Conclusions:

  • This study reveals a novel m6A-related ceRNA network (AC074117.1/miR-193a-3p/ALKBH5) in UCEC.
  • This network plays a significant role in promoting UCEC malignant progression.
  • The identified m6A-related ceRNA network holds potential as a target for early diagnosis and treatment of UCEC.
