Adaptive Mechanisms in Cancer Cells

Adaptive Mechanisms in Cancer Cells

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,...

Osteoclasts in Bone Remodeling

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Somatic to iPS Cell Reprogramming

Somatic to iPS Cell Reprogramming

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Area of Science:

Oncology
Cancer Metabolism
Biochemistry

Background:

Tumor cells exhibit metabolic reprogramming to fuel their growth and survival.
This reprogramming involves altered activity in key metabolic pathways like glycolysis and oxidative phosphorylation.
Osteosarcoma (OS) also displays distinct metabolic abnormalities linked to its malignant characteristics.

Purpose of the Study:

To review current research on metabolic alterations in Osteosarcoma.
To highlight the roles of glycolysis, amino acid metabolism, lipid synthesis, and the TCA cycle in OS.

Main Methods:

Literature review of studies on Osteosarcoma metabolism.
Analysis of metabolic pathways including glycolysis, pentose phosphate pathway, serine synthesis, glutamine metabolism, fatty acid synthesis, and oxidative phosphorylation (OXPHOS).

Main Results:

Metabolic reprogramming is crucial for cancer cell proliferation, migration, invasion, and drug resistance.
Specific metabolic pathways like glycolysis, amino acid metabolism, lipid synthesis, and the TCA cycle are significantly altered in OS.
These alterations contribute to the aggressive nature and treatment challenges in Osteosarcoma.

Conclusions:

Metabolic reprogramming is a hallmark of Osteosarcoma.
Understanding these metabolic shifts is vital for developing targeted therapies.
Further research into OS-specific metabolic vulnerabilities is warranted.
