Summary
Exosomes, tiny vesicles involved in cell communication, are increasingly recognized for their role in tumor resistance. Their unique composition makes them potential biomarkers for various diseases.
Area of Science:
- Cell Biology
- Biochemistry
- Oncology
Background:
- Extracellular vesicles (EVs) are lipid-bound structures secreted by cells, mediating intercellular communication.
- Exosomes, a subtype of EVs (30-100 nm), are found in body fluids and transport molecular cargo.
- Cancer cells release distinct exosomes, offering potential as disease biomarkers.
Purpose of the Study:
- To review current knowledge on exosomes.
- To explore the role of exosomes in tumor resistance mechanisms.
Main Methods:
- Literature review of scientific articles on exosomes and cancer.
- Analysis of exosome biogenesis, cargo, and function in tumor contexts.
Main Results:
- Exosomes play a significant role in intercellular communication within the tumor microenvironment.
- Cancer-derived exosomes can influence various processes, including immune suppression and drug resistance.
- Exosomal content reflects the cell of origin, highlighting their biomarker potential.
Conclusions:
- Exosomes are crucial mediators in tumor progression and resistance.
- Further research into exosome biology may lead to novel diagnostic and therapeutic strategies for cancer.

01:36Overview of Exosomes
3.3K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

5.3K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

02:17The Tumor Microenvironment
7.4K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

01:22MicroRNAs
3.5K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
