Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.7K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Setting Time of Cement01:12

Setting Time of Cement

943
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Negative Regulator Molecules01:23

Negative Regulator Molecules

38.9K
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.

M-Cdk Drives Transition Into Mitosis02:15

M-Cdk Drives Transition Into Mitosis

6.8K
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Area of Science:

  • Oncology
  • Molecular Biology
  • Chronobiology

Background:

  • The MYC oncogene is a key driver of oncogenesis.
  • Circadian rhythms regulate fundamental biological processes, including metabolism.
  • Disruptions in circadian rhythms are increasingly linked to cancer development.

Purpose of the Study:

  • To investigate the role of MYC in regulating the molecular clock within cancer cells.
  • To elucidate the connection between oncogenesis, circadian rhythm disruption, and metabolic alterations.

Main Methods:

  • Analysis of MYC expression in various cancer models.
  • Assessment of molecular clock gene expression and activity.
  • Metabolic profiling of cancer cells with altered MYC levels.

Main Results:

  • MYC was found to directly disrupt the molecular clock machinery in cancer cells.
  • This disruption leads to altered expression of key metabolic genes.
  • A direct link was established between MYC-driven oncogenesis and circadian dysregulation.

Conclusions:

  • MYC plays a critical role in desynchronizing the cellular clock in cancer.
  • Targeting the interplay between MYC, circadian rhythms, and metabolism may offer novel therapeutic strategies for cancer.
