Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
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...

Cancer Therapies

10.2K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

C4 Pathway and CAM01:27

C4 Pathway and CAM

49.3K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The C4 pathway is used by plants such as...

Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

1.5K
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Gene Therapy00:59

Gene Therapy

27.7K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Area of Science:

  • Biochemistry
  • Oncology
  • Metabolic pathways

Background:

  • Cholesterol regulates key signaling networks, including hedgehog and sterol-regulated pathways.
  • Cholesterol metabolism is increasingly recognized as a critical factor in cancer development and progression.
  • Proteins like SREBP2, SOAT1, NPC1, and PCSK9 are central to sterol-regulated pathways.

Purpose of the Study:

  • To clarify the intricate relationship between cholesterol metabolism and oncogenic signaling.
  • To review current mechanistic and translational evidence linking cholesterol to cancer.
  • To identify future research directions and therapeutic targets in cholesterol metabolism and cancer.

Main Methods:

  • Review of preclinical and clinical data.
  • Integration of mechanistic insights into oncogenic signaling.
  • Analysis of implicated pathways (SREBP, NPC1, PCSK9, SOAT1) in lipid metabolism.

Main Results:

  • Dysregulated cholesterol levels, potentially from high-fat diets, are linked to tumorigenesis.
  • Implicated pathways (SREBP, NPC1, PCSK9, SOAT1) promote a tumorigenic environment through lipid metabolism.
  • Cholesterol metabolism pathways present viable targets for metabolism-oriented anticancer strategies.

Conclusions:

  • Cholesterol metabolism dysregulation is a significant driver of cancer signaling and growth.
  • Key molecular targets within cholesterol metabolism pathways offer promise for future cancer treatments.
  • Future research should explore broader cancer types, combination therapies, and novel inhibitors.
