Summary
Entosis is a cell competition process where cancer cells engulf and kill neighbors. This study introduces methods to quantify entotic cell death and its link to LC3 lipidation, crucial for understanding cancer progression.
Area of Science:
- Cell Biology
- Cancer Research
- Autophagy
Background:
- Entosis is a cell competition mechanism observed in cancers.
- It involves the engulfment and subsequent death of neighboring cells.
- Entotic cell death is typically non-apoptotic and dependent on autophagy proteins.
Purpose of the Study:
- To present methodologies for quantifying entotic cell death.
- To analyze the association between entotic cell death and LC3 lipidation.
Main Methods:
- Development of novel methods to measure entotic cell death.
- Quantification of LC3 lipidation on entotic vacuoles.
Main Results:
- Established protocols for quantifying entotic cell death.
- Demonstrated the role of LC3 lipidation in entotic cell death.
Conclusions:
- The presented methods allow for accurate measurement of entotic cell death.
- Understanding LC3 lipidation in entosis can provide insights into cancer cell competition and survival.

4.5K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

9.8K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

01:16Methods for Studying Drug Absorption: In vitro
607
In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
