Summary
Lipid droplets, traditionally known for fat storage, are now recognized as crucial in inflammation and cancer. This review explores their structure, function, and roles in these diseases.
Area of Science:
- Cell Biology
- Biochemistry
- Oncology
Background:
- Lipid droplets were historically viewed primarily as passive fat storage organelles.
- Emerging research reveals dynamic and active roles beyond simple lipid accumulation.
Purpose of the Study:
- To review the established and novel functions of lipid droplets.
- To highlight their involvement in inflammatory pathways and cancer progression, particularly in cancer stem cells.
Main Methods:
- Literature review of recent studies on lipid droplet biology.
- Synthesis of findings concerning lipid droplet structure and function.
- Analysis of lipid droplet involvement in inflammation and cancer.
Main Results:
- Lipid droplets are active sites for the synthesis and storage of inflammatory mediators.
- These organelles play significant roles in the biology of cancer cells, including cancer stem cells.
Conclusions:
- Lipid droplets possess multifaceted functions extending beyond fat storage.
- Their roles in inflammation and cancer highlight them as potential therapeutic targets.

02:40Cancer Stem Cells and Tumor Maintenance
6.1K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.

01:18Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
4.6K
A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

01:35Cancer Cell Migration through Invadopodia
3.3K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

02:53Adaptive Mechanisms in Cancer Cells
7.2K
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,...

02:56Treatment Resistant Cancers
3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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...
