Abstract

Insights

NIMA related kinase 2 (NEK2) promotes gastric cancer (GC) cell proliferation by activating the ERK/MAPK pathway. Targeting NEK2 may improve patient survival in GC.

Area of Science:

  • Molecular oncology
  • Cancer signaling pathways

Background:

  • NIMA related kinase 2 (NEK2) is frequently over-expressed in cancers with poor prognoses.
  • The role of NEK2 in gastric cancer (GC) signaling remains unclear.
  • NEK2's association with mitosis suggests a potential role in cell proliferation.

Purpose of the Study:

  • To elucidate the role of NEK2 up-regulation in gastric cancer.
  • To investigate the impact of NEK2 on cellular signaling and proliferation in GC.

Main Methods:

  • Analysis of NEK2 expression in GC tissues using the Oncomain database and clinical samples.
  • Co-expression analysis of NEK2 and ERK using TCGA and qRT-PCR.
  • Investigation of NEK2's effect on ERK/MAPK signaling components (ERK, c-JUN, cyclin D1) and GC cell proliferation assays.

Main Results:

  • NEK2 is significantly up-regulated in human GC tissues.
  • NEK2 overexpression correlates with ERK expression and predicts poor prognosis in GC patients.
  • NEK2 knockdown inhibits ERK/MAPK signaling and cell proliferation; NEK2 can rescue ERK knockdown-induced inhibition.

Conclusions:

  • NEK2 promotes malignant proliferation in GC cells through the ERK/MAPK signaling pathway.
  • Targeting NEK2 represents a potential therapeutic strategy for improving GC patient survival.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Protein Kinases and Phosphatases02:54

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...

Yeast Signaling01:28

Yeast Signaling

Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

What is Cell Signaling?

Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Endocrine Signaling01:45

Endocrine Signaling

Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

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.
The mTOR pathway or the...
