Cancer cells

Area of Science:

  • Cell biology
  • Biophysics
  • Cancer research

Background:

  • Cancer cells commonly exhibit altered kinases and signaling pathways for growth on soft matrices.
  • Cytoskeletal protein alterations were previously considered secondary to these signaling changes.

Purpose of the Study:

  • To investigate the role of mechanosensory modules in cancer cell growth states.
  • To determine if cytoskeletal protein levels influence cancer cell adaptation to matrix rigidity.

Main Methods:

  • Comparing rigidity-sensing contractions in cancer cells versus normal cells from various tissues.
  • Manipulating cytoskeletal protein levels (tropomyosins, myosin IIA) to observe effects on growth states and rigidity sensing.
  • Assessing tumor formation and gene expression changes upon restoration of rigidity sensing.

Main Results:

  • Cancer cells displayed significantly fewer rigidity-sensing contractions than normal cells.
  • Restoring cytoskeletal proteins normalized rigidity sensing and promoted rigidity-dependent growth.
  • Depleting rigidity sensors induced transformed growth and blocked mechanosensing.

Conclusions:

  • Depletion of rigidity-sensing modules via cytoskeletal alterations enables cancer cell growth on soft substrates.
  • This mechanosensing deficiency is a key factor in cancer progression.
  • Targeting cytoskeletal components could offer new therapeutic strategies for cancer.

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.

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...

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...

Negative Regulator Molecules01:23

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Replicative Cell Senescence02:15

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
