Tumor Progression

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...

mTOR Signaling and Cancer Progression

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...

Cancer Therapies

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...

Genetics
Molecular Biology

Background:

Osteosarcoma is the most common bone cancer, predominantly affecting adolescents.
Recent molecular genetic studies are reshaping the understanding of its causes and treatments.

Purpose of the Study:

To review recent whole genome and exome studies on osteosarcoma.
To contextualize findings within the genetic hallmarks and mutational processes of osteosarcoma.
To explore candidate driver genes and their roles in osteosarcoma genesis using animal models.

Main Methods:

Summarization of whole genome and whole exome sequencing studies.
Analysis of genetic hallmarks and mutational processes in human osteosarcoma.
Review of genetic studies in other species and genetically engineered mouse models (GEMMs).

Main Results:

Osteosarcoma exhibits genomic complexity comparable to common adult cancers.
A synergistic combination of three drivers (one primary, two synergistic) may be necessary for aggressive osteosarcoma models.
Identified vulnerabilities offer opportunities for next-generation molecularly targeted therapies.

Conclusions:

More extensive sample analysis is required to fully catalog osteosarcoma driver mutations.
Understanding driver gene impact is key to predicting tumor latency, subtypes, and metastasis.
Further research is essential for developing reliable models and guiding new therapeutic strategies to improve osteosarcoma patient survival and quality of life.
