Cancer Therapies

8.6K
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...

Treatment Resistant Cancers

2.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Neurogenesis and Regeneration of Nervous Tissue

2.1K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Area of Science:

  • Neuro-oncology
  • Molecular Genetics
  • Medical Imaging

Background:

  • Gliomas are primary brain tumors with complex management challenges.
  • Recent research highlights significant progress in understanding glioma biology and treatment.

Purpose of the Study:

  • To summarize key recent advances in glioma diagnosis, molecular profiling, and therapeutic strategies.
  • To underscore the clinical implications of novel biomarkers and genetic discoveries.

Main Methods:

  • Review of recent reports on alkylator chemotherapy efficacy in high-grade gliomas.
  • Application of magnetic resonance spectroscopy for detecting 2-hydroxyglutarate in gliomas.
  • Analysis of genome-wide association studies (GWAS) identifying glioma risk single nucleotide polymorphisms (SNPs).
  • Utilizing high-throughput sequencing to identify mutations in histone-related genes in pediatric glioblastoma.

Main Results:

  • Confirmation of alkylator chemotherapy's role in specific high-grade gliomas, tied to molecular markers.
  • Magnetic resonance spectroscopy enables imaging of 2-hydroxyglutarate, a marker for isocitrate dehydrogenase (IDH) mutations in low-to-intermediate grade gliomas.
  • GWAS identified several SNPs associated with increased glioma risk.
  • Novel mutations in histone-coding and histone complex genes discovered in pediatric glioblastoma.

Conclusions:

  • New molecular markers and imaging techniques are revolutionizing glioma diagnosis and treatment response assessment.
  • Genetic insights from GWAS and sequencing are deepening the understanding of glioma pathogenesis.
  • These advances collectively pave the way for more personalized and effective glioma management strategies.
