Balancing Redox Equations02:58

Balancing Redox Equations

62.3K
Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

Metastasis02:30

Metastasis

6.6K
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...

Finding the Center of Gravity

4.4K
The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Equilibrium and Balance01:15

Equilibrium and Balance

6.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Energy Balance01:19

Energy Balance

1.2K
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Respiratory System Abnormal Finding I: Inspection and Percussion01:30

Respiratory System Abnormal Finding I: Inspection and Percussion

845
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Summary

The epithelial-to-mesenchymal transition (EMT) drives cancer spread. New research shows protein internalization affects cell movement during EMT, and epithelial plasticity influences pancreatic cancer metastasis to specific organs.

Area of Science:

  • Oncology
  • Cell Biology
  • Developmental Biology

Background:

  • The epithelial-to-mesenchymal transition (EMT) is a critical process in cancer metastasis.
  • Understanding the molecular mechanisms of EMT is crucial for developing effective cancer therapies.

Purpose of the Study:

  • To investigate the role of protein internalization in EMT-driven cell migration.
  • To identify factors determining metastatic organotropism in pancreatic cancer.

Main Methods:

  • Utilized cell-based assays to study EMT mechanisms.
  • Employed advanced imaging techniques to observe protein internalization.
  • Analyzed patient data to correlate epithelial plasticity with metastatic patterns.

Main Results:

  • Demonstrated that a specific EMT mechanism involving protein internalization significantly impacts cancer cell migration.
  • Identified epithelial plasticity as a key determinant of where pancreatic cancer spreads (metastatic organotropism).

Conclusions:

  • Protein internalization is a novel mechanism influencing cell migration during EMT.
  • Epithelial plasticity plays a significant role in directing pancreatic cancer metastasis to specific organs, offering potential therapeutic targets.
