  • Overexpression of polypeptide chain initiation factors is significant for cell transformation and malignancy.
  • mRNA structure plays a critical role in controlling the synthesis of growth regulatory proteins.
  • The protein kinase PKR (eIF2 alpha-specific) controls cell growth and apoptosis.
  • The elongation factor eEF1 is involved in oncogenesis.

Conclusions:

  • Protein synthesis regulation is a critical determinant of cancer development.
  • Targeting specific protein synthesis pathways presents potential therapeutic strategies for cancer treatment.
  • Further research into these mechanisms will likely yield significant advancements in oncology.
