Abstract

Insights

Never-in-mitosis A (NIMA)-related kinase 7 (NEK7) promotes gastric cancer cell proliferation and is linked to poor prognosis and immune infiltration. Inhibiting NEK7 may offer a new therapeutic strategy for gastric cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Immunology

Background:

  • Gastric cancer is a prevalent digestive system malignancy with slow-progressing targeted therapies.
  • Understanding gastric cancer cell behavior is vital for developing effective treatments.
  • Mammalian never-in-mitosis A (NIMA)-related kinases (NEKs) are implicated in cancer proliferation, but their role in gastric cancer remains unexplored.

Purpose of the Study:

  • To investigate the expression patterns and prognostic significance of NEK1-NEK11 in gastric cancer.
  • To elucidate the role of NEK7 in gastric cancer cell proliferation, immune infiltration, and related pathways.

Main Methods:

  • Bioinformatics analysis of NEK1-NEK11 expression and prognostic correlations.
  • Assessment of NEK7's impact on immune cell infiltration and associated pathways.
  • In vitro assays (EdU, cell cycle, CCK-8) to evaluate NEK7's effect on gastric cancer cell proliferation.
  • In vivo study using a mouse subcutaneous model to confirm NEK7's role in proliferation.

Main Results:

  • NEK7 is upregulated in gastric cancer, correlating with poor prognosis and advanced T-stage.
  • NEK7 expression is associated with the infiltration of multiple immune cells and gastric cancer-related pathways.
  • NEK7 promotes gastric cancer cell proliferation in vitro and in vivo.
  • NEK7 inhibition leads to suppressed proliferation and G1/S cell cycle arrest in gastric cancer cells.

Conclusions:

  • NEK7 significantly regulates gastric cancer cell proliferation.
  • NEK7 is closely associated with tumor immune infiltration in gastric cancer.
  • Targeting NEK7 may represent a novel therapeutic strategy for gastric cancer.

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.
The mTOR pathway or the...

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...

Tumor Progression02:07

Tumor Progression

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...

Mitogens and the Cell Cycle02:38

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...

Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Adaptive Mechanisms in Cancer Cells02:53

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,...
