Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.2K
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 Survival Analysis01:21

Cancer Survival Analysis

853
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

mTOR Signaling and Cancer Progression

5.1K
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...

Adaptive Mechanisms in Cancer Cells

7.6K
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,...

Area of Science:

  • Oncology
  • Metabolism
  • Biomedical Imaging

Background:

  • Cancer cachexia is a debilitating syndrome involving significant loss of skeletal muscle and fat mass.
  • It is not fully reversible with nutritional support, highlighting the need for better understanding and treatment.
  • Current knowledge of cancer cachexia mechanisms is limited, and therapeutic options remain scarce.

Purpose of the Study:

  • To review recent studies on the mechanisms and pathways involved in cancer cachexia.
  • To examine the role of molecular and functional imaging in early cachexia detection.
  • To assess the utility of imaging in identifying metabolic targets and evaluating treatment efficacy.

Main Methods:

  • Literature review of recent studies on cancer cachexia.
  • Focus on molecular and functional imaging techniques.
  • Analysis of identified mechanisms, pathways, and therapeutic targets.

Main Results:

  • Recent studies are beginning to elucidate the complex mechanisms underlying cancer cachexia.
  • Molecular and functional imaging show promise for earlier diagnosis and monitoring.
  • Imaging can help identify key metabolic pathways and assess treatment responses.

Conclusions:

  • Further research into cancer cachexia mechanisms is crucial for developing effective therapies.
  • Advanced imaging techniques offer new avenues for early detection and personalized treatment strategies.
  • Integrating imaging into cachexia research can accelerate the development of interventions.
