Apoptosis News and Research

RSS

Apoptosis is programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

Subpopulations of tumor cells may exhibit diverging behaviors from bulk tumor

Subpopulations of tumor cells may exhibit diverging behaviors from the bulk tumor due to an alternate stress response that diverts tumor cells from apoptotic death.

Cell factors decide if a cancer grows or dies, says new study

A new study published today in the journal Cell Reports by scientists at the German Cancer Research Center (DKFZ) shows that the direction taken by a cancer cell depends on the configuration of the cell itself as well as the activation of a universal cancer cell receptor called CD95.

Researchers discover new pathway to 'reprogram' killer cells

Killer cells of the immune system detect and kill infected cells or cancer cells. Researchers at the Institute of Pathology at the University of Bern have now discovered that the mechanism by which certain immune cells kill their target cells can also be used to control the killer cells themselves.

Lithium corrects radiation damage to brain in young cancer patients

A new study on mice, published online in the journal Molecular Psychiatry, on November 14, 2019, shows that the intermittent use of lithium, which is widely used to stabilize the mood in conditions such as bipolar disorder, can correct memory and learning losses due to radiation therapy to the brain in very young animals, even when the lithium is given long after the injury.

Clinical analysis reveals high expression of apoptosis protein in chemoresistant TNBC

78 TNBC biopsies from patients with different responses to chemotherapy were analysed for API-5 expression before any treatment.

White blood cells control final moments of their death

La Trobe University researchers have revealed for the first time how white blood cells control the final moments of their death, helping their own removal from the human body.

Contraceptive drug effective in preventing and regressing cervical cancer in mice

A new study in The American Journal of Pathology, published by Elsevier, reports that medroxyprogesterone acetate (MPA), the active ingredient in the common contraceptive injection Depo-Provera, was effective in preventing the development of cervical cancer in mice with precancerous lesions.

Finding ways to stop cancer at its roots

Why do some cancers come back? Sometimes, a treatment can effectively eliminate cancer cells to undetectable levels, but, if the treatment stops, cancer may return.

Researchers discover new process of antitumor response of NK cells in myeloma

NK cells mean Natural Killer cells. They are part of the innate immune system. They are known primarily for their ability to recognize and kill tumor cells, cells infected by viruses and bacteria, or dying by apoptosis. Although evidence about their antitumoral capacity, how this activity occurred remained unknown.

Study identifies a kinase as potential target to treat heart failure

An unexplored kinase in heart muscle cells may be a good target to treat heart failure, a disease that is only incrementally delayed by existing therapies.

Study shows how Chlamydia bacteria enter human cells

Chlamydia are bacteria that can infect human and animal cells. Human health is particularly affected by Chlamydia pneumoniae (Cpn) and Chlamydia trachomatis.

Chemotherapy-induced senescent cells eat neighboring cells

A new study has found that chemotherapy-induced senescent cancer cells feed on other neighboring cells to enhance their survival.

Novel, cost-effective method successfully identifies aggressive tumors

Researchers have developed a novel, cost-effective genomic method that can identify highly heterogenous tumors that are typically aggressive in nature.

Study shows how cell competition corrects noisy morphogen gradients during embryogenesis

Tissue patterning is an important process during embryo formation, as well in adult tissue, which ensures that groups of cells are correctly arranged to allow them to function properly.

Fullerene compounds can effectively kill non-small-cell lung carcinoma cells

The team of scientists from Skoltech Center for Energy Science and Technology, the Institute for Problems of Chemical Physics of Russian Academy of Sciences and National Taiwan University have discovered that fullerene compounds can effectively kill non-small-cell lung carcinoma cells and found out the mechanisms behind their anti-tumor activity.

22 Oct 2019

Researchers identify compound effective in killing chemotherapy-resistant cancer cells

A compound effective in killing chemotherapy-resistant glioblastoma-initiating cells has been identified, raising hopes of producing drugs capable of eradicating refractory tumors with low toxicity.

Scientists discover novel virus that may shed light on viral evolution

Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on. But what happens if a virus lacks the proper tools to infect an organism? How can it propagate?
