Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

6.9K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Overview of Protein Metabolism

3.6K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.6K
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

9.8K
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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

5.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.6K
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...

Area of Science:

  • Oncology
  • Nutritional Science
  • Metabolic Research

Background:

  • Cancer cachexia is a debilitating syndrome affecting patient survival and quality of life.
  • Current nutritional support is often inadequate for managing cachexia.
  • No standardized treatment or approved nutritional approach exists for cancer cachexia.

Purpose of the Study:

  • To review recent research on nutritional interventions for cancer cachexia.
  • To highlight supplements targeting skeletal muscle sparing and molecular pathways.
  • To explore potential strategies for managing cancer cachexia.

Main Methods:

  • Review of recent scientific literature on nutrition and cancer cachexia.
  • Focus on preclinical and clinical studies of specific nutrient supplements.
  • Analysis of molecular pathways and physiological effects of interventions.

Main Results:

  • Branched-chain amino acids (BCAAs) and alanine dipeptide restore muscle proteostasis and enhance anabolic signaling.
  • Alpha-ketoisocaproate and methionine derivatives protect against muscle loss via specific signaling pathways.
  • L-carnitine and omega-3 polyunsaturated fatty acids offer anti-inflammatory and muscle-protective benefits.

Conclusions:

  • Nutrient-based interventions show potential in addressing cancer cachexia.
  • Combinatorial approaches integrating multiple nutrients may form an effective management strategy.
  • Future interventions against cancer cachexia could be built upon these findings.
