Summary
Aging significantly contributes to cancer progression and metastasis by altering host metabolism, not just through accumulated mutations. The aging process actively supports malignancy development.
Area of Science:
- Oncology
- Gerontology
- Metabolism
Background:
- Aging is a primary risk factor for cancer development.
- The relationship between aging and cancer involves more than just increased exposure to carcinogens.
Purpose of the Study:
- To investigate the role of host metabolic deregulation in aging-associated cancer progression and metastasis.
- To elucidate how the aging process itself contributes to the coordination of factors required for malignancy.
Main Methods:
- Analysis of human serum from aged individuals.
- Demonstration of tumor progression and metastasis in the context of aged host metabolism.
Main Results:
- Tumor progression and metastasis are, in part, a consequence of global metabolic deregulation in aged hosts.
- The aging process actively coordinates mechanisms that promote malignancy.
Conclusions:
- The impact of aging on cancer is a complex biological process involving metabolic coordination, not solely cumulative DNA damage.
- Targeting metabolic deregulation in aged individuals may offer new strategies for cancer prevention and treatment.

6.1K
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,...

03:03mTOR Signaling and Cancer Progression
4.0K
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.

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...

01:22PI3K/mTOR/AKT Signaling Pathway
4.4K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

02:21Cancers Originate from Somatic Mutations in a Single Cell
13.4K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

02:15Replicative Cell Senescence
4.0K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
