Insights

The Lin28 RNA-binding protein and let-7 microRNA pathway regulates cell metabolism. This pathway influences tissue repair and drives cancer development by altering cellular metabolism.

Area of Science:

  • Cellular metabolism
  • Developmental biology
  • Oncogenesis

Background:

  • Malignant cells display significant metabolic changes.
  • The let-7 microRNA and Lin28 RNA-binding protein pathway regulates embryonic development.
  • Lin28 is an oncogene that promotes tumorigenesis by suppressing let-7.

Purpose of the Study:

  • To review the current understanding of how Lin28 affects cellular metabolism.
  • To explore the regenerative and oncogenic effects mediated by metabolic mechanisms of Lin28.

Main Methods:

  • Literature review of studies on Lin28, let-7, and cellular metabolism.
  • Analysis of the role of Lin28 in regulating glucose metabolism.
  • Examination of the metabolic reprogramming during tissue repair and injury.

Main Results:

  • The Lin28/let-7 pathway is implicated in regulating glucose metabolism in adult mice.
  • Lin28 reprograms cellular metabolism during tissue injury and repair.
  • Lin28's oncogenic program is increasingly understood through its metabolic effects.

Conclusions:

  • The Lin28/let-7 pathway plays a critical role in metabolic regulation.
  • Lin28 utilizes metabolic mechanisms to promote both regeneration and oncogenesis.
  • Further research into these metabolic underpinnings is crucial for understanding cancer and development.

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...

PI3K/mTOR/AKT Signaling Pathway

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...

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.

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
