Death of cells is well tested: a new machine of diesel appliances appeared


An important part of the microscopic machines that carry cell death is marked by Walter scientists and Hall Eliza Institute.

Analyzing the tools & # 39; pro-death & # 39; Devastated devices that have been damaged, caused by disease or a variety are required to die, the VDAC2 protein research team was indispensable for Bax's predominant proxy death.

The team also showed that VDAC2 is helping to kill some of the cancer cells by anti-cancer agents. The research, published today in the magazine Natural Communications, led by Professor Hui-San Chin, PhD student with Professor David Huang, Dr Mark van Delft and Professor Grant Dewson.


  • Cell deaths with a process called apoptosis are essential for removing unnecessary cells, damaged or infected, and is driven by a well-designed protein device .
  • Bax protein is a key component of cell death devices, which is part of a complex that causes cellular cells; point of no return in apoptotic death.
  • Our researchers found a protein called VDAC2 which helps Bax to support apoptosis, and & # 39; they may have a role in responding to the response of cancer cells to cancer replacing agents.


Cell death has been essential for the development and maintenance of a body, and the respiratory devices that have a apoptosis drive have been tied to a variety of diseases. Problems of severe depression have been linked to cancer development, as well as the treatment of cancer cells.

Bax, Dr van Delft, is known as the main protein in cell death devices. "Bax helps to bring cells to" point to return "when the death of apoptotic cells is encouraged, and creates pores in mitochondria, cell power houses . This eliminates the last & # 39; prodigals that delete your cell.

"Understanding how Bax's actions can continue to a new system that triggers cell death – with claims for diseases such as cancer – or cure that prevents cell death, which is capable of to save cells in situations such as neurodegenerative disorders or stroke, "he said.

The team investigated how Bax and a protein related to the Outcome kill cells, Expression of gene genes that use CRISPR technology, Professor Dewson said.

"In amazement, we found a gene that was necessary for the work of Bax but not Bak, notwithstanding these two protons actively and a very similar structure.

"We were able to continue with this research to show that the protein, known as VDAC2, was a Bax-protected guardian associated with mitochondria and producing pores in the leaflets , to kill her husband, "said Dewson. "VDAC2's daily work is to maintain the work of mitochondria, pumping metabolites into and out of the mitochondria."


The failure of cellular device cells is a sign of cancer cells, and is linked to the cancer cells' disease to cancer medications, said Dr. Huang.

"Bax is important in helping cancer agents to kill cells – without Bax and his Bak, who are related to him, cancer cells can not get apoptosis when treated with a variety of medications against cancer.

"Our research shows that VDAC2 for Bax needs to be driving the response of cancer cells to current chemotherapy agents as well as the recently developed BH3-mimetics," said the Chief Professor Huang.


The research was supported by the National Council for Health and Medical Research of Australia, the Australian Research Council, Canse Victoria Council, Australian Cancer Research Trust, the Lemphoma Association of Lymphoma (SA) and Victoria Government. Dr Hui San Chin received PhD scholarship from Melbourne University.
