Abstract

Insights

Ribosomal protein S15a (RPS15a) is elevated in gastric tumors. Silencing RPS15a inhibits gastric cancer cell proliferation, growth, and migration, suggesting RPS15a as a potential therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Information on the role of ribosomal protein S15a (RPS15a) in gastric cancer is limited.
  • Gastric cancer remains a significant global health concern, necessitating the identification of novel therapeutic targets.

Purpose of the Study:

  • To investigate the impact of RPS15a gene expression on gastric cancer cell growth and cell cycle progression.
  • To evaluate the potential of RPS15a as a therapeutic target in gastric cancer.

Main Methods:

  • RPS15a mRNA expression was quantified in gastric tumor tissues and adjacent normal tissues from 40 patients.
  • RPS15a was silenced in the BGC823 gastric cancer cell line using lentivirus-mediated RNA interference.
  • Cell proliferation, migration, colony formation, cell cycle, and in vivo tumorigenicity were assessed.

Main Results:

  • RPS15a expression was significantly higher in gastric tumor tissues compared to normal tissues.
  • RPS15a silencing led to decreased cell proliferation, G0/G1 phase arrest, and reduced migration in BGC823 cells.
  • In vivo studies demonstrated that RPS15a silencing inhibited tumor volume and mouse weight.

Conclusions:

  • Elevated RPS15a expression in gastric tumors correlates with aggressive cancer cell phenotypes.
  • RPS15a plays a crucial role in promoting gastric cancer cell proliferation, growth, and migration.
  • RPS15a represents a promising therapeutic target for gastric cancer treatment.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Cell Migration01:19

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Gastric Motility01:16

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

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...
