mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.6K
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...

Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

5.0K
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,...

Abnormal Proliferation

5.1K
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

7.2K
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...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

3.2K
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,...

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Oncology

Background:

  • Stathmin is a phosphoprotein crucial for cell proliferation, differentiation, and motility.
  • Cancer is characterized by deregulated cell proliferation, tumor growth, and invasion.
  • Stathmin is upregulated in many neoplasms, correlating with metastasis and high proliferation.

Purpose of the Study:

  • To elucidate the role of stathmin in cellular signaling pathways.
  • To investigate stathmin's involvement in cell cycle control and cancer pathogenesis.
  • To understand stathmin's coordination of extracellular matrix signaling, cell adhesion, and motility.

Main Methods:

  • Analysis of stathmin's influence on cell proliferation and differentiation.
  • Investigation of stathmin's role in cell cycle checkpoints (G1-S and G2-M).
  • Examination of stathmin's interactions with cell cycle proteins (p53, rb) and metastasis-related genes.

Main Results:

  • Stathmin mediates cellular signals involved in differentiation, morphogenesis, and proliferation.
  • Stathmin influences microtubule dynamics, affecting cell cycle progression at G1-S and G2-M checkpoints.
  • Stathmin coordinates signaling pathways related to extracellular matrix, cell adhesion, and motility.

Conclusions:

  • Stathmin plays a central role in regulating fundamental cellular processes.
  • Dysregulation of stathmin function has significant implications for cancer development and progression.
