Insights

Osteosarcoma, a common bone cancer in young people, has seen little treatment progress due to its complex biology. This review covers osteosarcoma's genetics, epigenetics, and emerging therapies.

Area of Science:

  • Oncology
  • Genetics
  • Molecular Biology

Background:

  • Osteosarcoma is the most frequent primary bone cancer, predominantly affecting adolescents and young adults.
  • Despite its prevalence, clinical outcomes for osteosarcoma patients have remained stagnant for over three decades.
  • The limited therapeutic progress is attributed to the intricate genetic, epigenetic, and biological nature of this rare malignancy.

Purpose of the Study:

  • To provide a comprehensive overview of osteosarcoma biology and the current clinical landscape.
  • To detail the known genetic and epigenetic alterations characteristic of osteosarcoma.
  • To discuss ongoing research initiatives and novel therapeutic strategies under investigation for osteosarcoma.

Main Methods:

  • Literature review synthesizing current knowledge on osteosarcoma.
  • Enumeration of identified genetic and epigenetic defects in osteosarcoma.
  • Discussion of findings from large-scale studies and emerging therapeutic targets.

Main Results:

  • Osteosarcoma presents significant biological complexity, hindering therapeutic advancements.
  • Numerous genetic and epigenetic alterations have been identified, contributing to tumor development and progression.
  • Several large-scale studies are underway, exploring new avenues for osteosarcoma treatment.

Conclusions:

  • Understanding the complex biology of osteosarcoma is crucial for improving patient outcomes.
  • Continued research into genetic and epigenetic factors is essential for developing targeted therapies.
  • Emerging therapeutic strategies hold promise for overcoming the current treatment stagnation in osteosarcoma.

Cancer Therapies

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...

mTOR Signaling and Cancer Progression

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

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...

Mitogens and the Cell Cycle

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...

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
