The Tumor Microenvironment02:17

The Tumor Microenvironment

7.8K
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...

Phase-lead and Phase-lag Controllers

574
Understanding the working function of different types of controllers can be illustrated with practical analogies, such as adjusting a stereo's volume equalizer. Cranking up the bass involves a phase-lead controller, which functions as a high-pass filter, while increasing the treble uses a phase-lag controller, which acts as a low-pass filter. PD controllers, similar to high-pass filters, enhance the system's response to high-frequency components. PI controllers, akin to low-pass...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

14.3K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Overview of Metabolism01:40

Overview of Metabolism

38.5K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Regulation of Metabolism01:19

Regulation of Metabolism

11.6K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Area of Science:

  • Oncology
  • Cancer Biology
  • Cellular Metabolism

Background:

  • The tumor microenvironment (TME) comprises cancer cells, fibroblasts, lymphocytes, and immune cells, influencing cancer development.
  • Cancer cell heterogeneity, including proliferation, metabolism, and gene expression, presents treatment challenges.
  • The TME is dynamic, constantly evolving and forcing cancer cells to adapt.

Purpose of the Study:

  • To discuss the role of the tumor microenvironment in cancer progression.
  • To explore how specific tumor microenvironments drive metabolic adaptations in cancer cells.

Main Methods:

  • Literature review and synthesis of current research on tumor microenvironments and cancer metabolism.

Main Results:

  • Different tumor microenvironments induce distinct metabolic adaptations in cancer cells.
  • These metabolic changes are critical drivers of cancer progression.

Conclusions:

  • The heterogeneity of tumor microenvironments significantly impacts cancer cell metabolism.
  • Targeting TME-driven metabolic adaptations offers a promising avenue for novel cancer therapies.
