Protein Transport to the Stroma01:24

Protein Transport to the Stroma

2.3K
Chloroplasts are triple membrane structures with an outer membrane, an inner membrane, and a thylakoid membrane, each containing distinct metabolite transporters, membrane translocons, and enzymes. Appropriate sorting and translocating these proteins to their correct membrane systems is essential for chloroplast function.
Protein complexes called the translocon of the outer chloroplast membrane or TOC complex, and the translocon of the inner chloroplast membrane or TIC complex mediate the...

Tumor Immunotherapy01:27

Tumor Immunotherapy

2.0K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Tumor Progression02:07

Tumor Progression

7.5K
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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.9K
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...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer 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.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

6.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Area of Science:

  • Oncology
  • Immunology
  • Biochemistry

Background:

  • Intratumoral fibrosis involves collagen deposition by cancer-associated fibroblasts (CAFs).
  • Fibrosis creates mechanical and biochemical conditions influencing tumor immunity and metastasis.
  • Understanding these processes is crucial for developing effective cancer therapies.

Purpose of the Study:

  • To review recent evidence on the regulation of CAFs and tumor cells by provisional matrix molecules.
  • To examine how changes in stromal collagen cross-linking contribute to metastasis.
  • To discuss the perpetuating relationship between fibrosis and inflammation in tumors.

Main Methods:

  • Review of existing scientific literature and recent evidence.
  • Analysis of molecular mechanisms regulating CAFs and tumor cells.
  • Examination of the role of collagen cross-linking in metastasis.

Main Results:

  • CAFs and tumor cells are regulated by provisional matrix molecules.
  • Metastasis is linked to alterations in stromal collagen cross-linking.
  • Tumor fibrosis and inflammation are interconnected via proteolytic and chemotactic mediators.

Conclusions:

  • The interplay between fibrosis, inflammation, and collagen cross-linking significantly impacts cancer progression.
  • Emerging biological insights into these mechanisms hold therapeutic potential for cancer treatment.
