Injured Cancer Cells Can Survive on Their Own Membranes

Scientists believe that patching the cells might get rough and the cells might need a complete repair in future.

Cancer uses all kinds of tricks for its growth. In Denmark, scientists have found a new such trick by which cancer spreads. The scientists found that cells of cancer employ strategies seen in other cell types involving repair and consumption of the damaged membranes that offer enticing possibilities to relate and kill them. This study was carried out by cancer researchers from Copenhagen University. The scientists main focus was on the membranes that are important to cellular content (might be cancerous or other).

A breakdown in the membrane may cause the fluid to escape and completely destroy the cell. If cells suffer these forms of membrane harm, then the treatment used to cure the cell or repair the damage is called macropinocytosis. This shows that the cells encompass the injured section with an intact membrane section and screens the cell in minutes. The injured membrane section is then broken down into small spaces that pass along the lysosomes of the cell, acting as the ‘tummy’ to decompose them. Never before had this been seen in cancer cells. The researchers studied cancer cells in the laboratory, and they shot tiny cracks in the membranes with a laser. The team discovered that macropinocytosis was triggered and also found that it was able to get involved with compounds that prevent the formation of the tiny cracks. This helps to prevent the digestion procedure and also prevents the cancer cells from fixing itself and leading them to death.

Jesper Nylandsted the group leader of the study stated that the study gives basic information about the survival of cancer cells. In these experiments the scientists have also demonstrated that, in the event of inhibition, cancer cells will die and that macropinocytosis is an objective of diagnostic purpose. More aggressive cancer cells which tends to spread in the body of the person also rely more on macropinocytosis considering the fact that their membranes are generally damaged more during their movement via the tissue. That would give them a lot of defective recyclables and the energy they need to divide instantly.
