Insights

Peptidyl-prolyl isomerase (Pin1) regulates proteins involved in cancer. Inhibiting Pin1, which is overexpressed in many cancers, shows promise for new cancer therapies.

Area of Science:

  • Molecular Biology
  • Biochemistry
  • Cancer Biology

Background:

  • Protein phosphorylation and post-translational modifications are key regulators of cellular signaling pathways.
  • Peptidyl-prolyl isomerase (Pin1) is a unique enzyme that isomerizes proline-containing phosphorylated motifs.
  • Pin1 interacts with numerous phosphorylated proteins, influencing their conformation and activity, which is critical in tumorigenesis.

Purpose of the Study:

  • To review the critical role of Pin1 in various types of cancer.
  • To discuss the current development status of Pin1 inhibitors as a potential cancer therapeutic strategy.

Main Methods:

  • Literature review of studies on Pin1 function in cancer.
  • Analysis of the role of proline-directed phosphorylation in tumorigenesis.
  • Overview of current Pin1 inhibitor development.

Main Results:

  • Pin1 is overexpressed and/or activated in a wide range of cancers.
  • Dysregulation of proline-directed phosphorylation by Pin1 contributes significantly to cancer development.
  • Pin1's role in regulating oncogenic and tumor-suppressive proteins makes it a viable therapeutic target.

Conclusions:

  • Pin1 is a crucial mediator in cancer development due to its regulation of key signaling proteins.
  • Targeting Pin1 with inhibitors represents a promising therapeutic avenue for various cancers.

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.

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
