Insights

The regulation of protein biosynthesis and ribosome biogenesis is crucial for cell growth. Disruptions in these processes are linked to cancer, but their direct role in neoplastic transformation needs further study.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Oncology

Background:

  • Translation regulation and ribosome biogenesis are vital cellular functions impacting cell growth and proliferation.
  • Dysregulation of protein biosynthesis is linked to altered cell growth and cell cycle control.
  • Tumor suppressors and proto-oncogenes influence these processes, potentially regulating cancer progression via the protein synthesis machinery.

Purpose of the Study:

  • To explore the intricate relationship between protein biosynthesis regulation and cancer.
  • To investigate the necessity and sufficiency of protein biosynthesis deregulation in neoplastic transformation and metastasis.

Main Methods:

  • Literature review and analysis of existing studies correlating protein biosynthesis with cancer.
  • Examination of the roles of tumor suppressors and proto-oncogenes in protein synthesis pathways.
  • Analysis of cell growth and proliferation regulatory mechanisms.

Main Results:

  • Protein biosynthesis and ribosome biogenesis are fundamental to cell growth and proliferation.
  • Alterations in protein synthesis control are associated with cell cycle dysregulation.
  • Evidence suggests tumor suppressors and proto-oncogenes impact malignant progression through the protein synthetic machinery.

Conclusions:

  • While deregulation of protein biosynthesis is correlated with cancer, its precise role in initiating and driving neoplastic transformation and metastasis requires further investigation.
  • Understanding these pathways is critical for potential cancer therapeutic strategies.

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.

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

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...

Regulation of Expression at Multiple Steps

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
