Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

8.3K
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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

5.0K
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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

7.7K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

10.2K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.1K
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...

Area of Science:

  • Neuroscience
  • Oncology
  • Cancer Biology

Background:

  • The nervous system is traditionally viewed as a passive player in cancer, transmitting pain and facilitating invasion.
  • Emerging evidence suggests a more active role for neural pathways in cancer development and progression.

Purpose of the Study:

  • To review recent studies investigating the direct role of the nervous system in cancer progression.
  • To discuss the implications of neural signaling in tumorigenesis.

Main Methods:

  • Review of recent scientific literature and studies.
  • Analysis of findings from animal models of visceral and somatic cancer.
  • Examination of the impact of stress reduction and sympathetic nerve suppression on cancer outcomes.

Main Results:

  • Reducing stress or sympathetic drive correlates with improved cancer outcomes and survival.
  • Nerve ablation in animal models significantly impacted disease progression, delaying precancerous lesions and reducing tumor growth and metastasis.
  • Evidence supports a direct role for the nervous system in modulating cancer progression.

Conclusions:

  • The nervous system is an active participant in cancer progression, influencing tumorigenesis.
  • Future research should further explore neural signaling pathways for potential therapeutic targets in cancer treatment.
