Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

5.2K
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,...

Stem Cell Niche

6.5K
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

The Cell Cycle Control System

6.3K
The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.
Cyclins and cyclin-dependent kinases (Cdks) are the primary cell cycle regulators and...

The Cell Cycle Control System

14.8K
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...

Area of Science:

  • Oncology
  • Cell Biology
  • Cancer Research

Background:

  • Nasopharyngeal carcinoma (NPC) is an aggressive malignancy with high metastatic potential.
  • Epstein-Barr virus (EBV) encoded small RNA (EBER) and latent membrane protein 1 (LMP1) are implicated in NPC pathogenesis.
  • Store-operated calcium (SOC) entry is crucial for various cellular functions, including cell migration and invasion.

Discussion:

  • This commentary discusses the findings of Wei et al. regarding the role of LMP1-modulated SOC entry in NPC metastasis.
  • It highlights how blocking SOC entry can inhibit NPC cell migration and invasion.
  • The discussion emphasizes the potential of targeting calcium signaling pathways for NPC treatment.

Key Insights:

  • LMP1, a key EBV oncoprotein, significantly enhances SOC entry in NPC cells.
  • Inhibition of SOC entry, by blocking ORAI1 channels, effectively reduces NPC cell migration and invasion.
  • Targeting LMP1-mediated calcium influx presents a promising therapeutic strategy to combat NPC metastasis.

Outlook:

  • Further research is warranted to explore the clinical applicability of targeting SOC entry in NPC.
  • Developing specific inhibitors of ORAI1 or other SOCE components could lead to novel anti-metastatic therapies for nasopharyngeal carcinoma.
  • Understanding the intricate interplay between EBV oncoproteins and calcium signaling is crucial for advancing NPC treatment strategies.
