Insights

N-myristoyltransferase (NMT) activity and expression are elevated in colorectal cancer, suggesting its potential as an early detection marker. NMT inhibitors may offer new therapeutic strategies for cancer treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Colorectal cancer is a leading cause of cancer death, necessitating improved preventive and therapeutic strategies.
  • Effective chemotherapeutic agents for colon cancer are limited, driving the search for novel cellular targets.
  • The role of protein myristoylation, mediated by N-myristoyltransferase (NMT), in cancer pathogenesis is not well understood.

Purpose of the Study:

  • To investigate the role and potential of N-myristoyltransferase (NMT) in colorectal cancer and other malignancies.
  • To explore NMT as a potential biomarker for early cancer detection.
  • To evaluate NMT as a therapeutic target for anticancer drug development.

Main Methods:

  • Analysis of NMT activity and protein expression in human colorectal cancer, gallbladder carcinoma, and brain tumors.
  • Assessment of NMT activity during early stages of colonic carcinogenesis.
  • Review of laboratory findings on NMT in cancer.

Main Results:

  • NMT activity and protein expression were found to be significantly higher in human colorectal cancer, gallbladder carcinoma, and brain tumors.
  • Increased NMT activity was observed at an early stage of colonic carcinogenesis.
  • HSC70 and enolase are proposed as potential anticancer therapeutic targets.

Conclusions:

  • NMT is upregulated in various human cancers, indicating its involvement in cancer pathogenesis.
  • NMT may serve as a valuable biomarker for the early detection of cancer.
  • Targeting NMT with specific inhibitors presents a promising avenue for developing novel anticancer therapies.

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.

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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 daughter...
Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

Allosteric Proteins-ATCase

Binding sites linkages can regulate a protein's function.  For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to  N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
