Summary
Galectins are proteins with varied functions inside and outside cells. This review explores their roles in cancer, including tumor growth, spread, and immune evasion.
Area of Science:
- Biochemistry
- Molecular Biology
- Cancer Research
Background:
- Galectins are a diverse family of animal lectins.
- They exhibit both extracellular and intracellular functions, interacting with various cellular components.
- Emerging evidence highlights galectins' significant involvement in cancer biology.
Purpose of the Study:
- To explore the multifaceted roles of galectins in cancer.
- To understand how different galectin family members contribute to tumor development, progression, and immune evasion.
Main Methods:
- Literature review of current research on galectins and cancer.
- Analysis of galectin functions in neoplastic transformation, survival, angiogenesis, and metastasis.
- Examination of galectins' impact on immune and inflammatory responses in the tumor microenvironment.
Main Results:
- Galectins influence key cancer processes such as cell transformation, survival, blood vessel formation (angiogenesis), and metastasis.
- They play a role in modulating immune responses and may help tumors evade immune surveillance.
- Different galectin members likely contribute distinct functions to tumor biology.
Conclusions:
- Galectins are critical regulators of multiple aspects of cancer.
- Understanding the specific roles of individual galectins is crucial for developing targeted cancer therapies.
- Further research into galectin functions could reveal novel therapeutic strategies for cancer treatment.

02:07Tumor 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...

02:53Adaptive 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,...

03:03mTOR 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.
