Insights

Inhibitor of apoptosis stimulatory protein phosphatase (iASPP) knockdown decelerated bladder cancer cell growth. This suggests iASPP is a potential therapeutic target for bladder cancer gene therapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Inhibitor of apoptosis stimulatory protein phosphatase (iASPP) is a key regulator of p53, implicated in cell proliferation and carcinogenesis.
  • iASPP's role in tumor cell apoptosis makes it a potential target for cancer gene therapy.
  • The relevance of iASPP in p53-deficient human bladder cancer remains unclear.

Purpose of the Study:

  • To investigate the role of iASPP in the proliferation of p53-defective human bladder cancer cells.
  • To determine if iASPP is a viable therapeutic target for bladder cancer.

Main Methods:

  • Knockdown of iASPP in bladder carcinoma cell lines (5637 and T24) using lentiviral-mediated short hairpin RNAs (siRNAs).
  • Assays performed include MTT assay, BrdU incorporation assay, and colony formation assay to assess cell proliferation.

Main Results:

  • iASPP knockdown resulted in significant deceleration of cell growth.
  • Colony formation was notably slower in cells with reduced iASPP expression.
  • A positive correlation was observed between iASPP expression levels and bladder cancer cell proliferation.

Conclusions:

  • iASPP expression is critical for the proliferation of bladder cancer cells.
  • Targeting iASPP may represent an effective therapeutic strategy for bladder cancer.

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 daughter...
iPS Cell Differentiation01:22

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the goblet,...
