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

Study shows how Cisplatin chemotherapy leads to neuronal apoptosis

Despite the great advances in cancer research in recent years, treatments that can cause very severe adverse effects are still used. This is the case of neuropathy caused by chemotherapy with platinum derivatives, such as Cisplatin and Oxaliplatin.

Exosomes yield regenerative benefits equivalent to hiPSC-CCs, shows study

Science has long known that recovery from experimental heart attacks is improved by injection of a mixture of heart muscle cells, endothelial cells and smooth muscle cells, yet results have been limited by poor engraftment and retention, and researchers worry about potential tumorigenesis and heart arrhythmia.

Induction of acute senescence may be a necessary process in hemorrhagic shock

It's called senescence, when stressed cells can no longer divide to make new cells, and it's considered a factor in aging and in some diseases.

New material identifies cancer cells and mounts a surprising attack

Many people across the globe are working hard to get the better of cancer; however cancer is always working too. Cancer cells can become resistant to the methods that have been adopted to kill them, so identifying drugs that act in different ways is part of the push to outsmart this ubiquitous disease

AI used to define the cytokine storm implicated in fatal COVID-19

A new study published on the preprint server bioRxiv* in September 2020 reports the use of artificial intelligence (AI) to identify an invariant or universal host immune response found in all viral pandemics so far. The association of this response with severe COVID-19 phenotypes indicates a new understanding of the human immune response in viral pandemics.

Study: R-spondin growth factor reduces intestinal tumors in early phase of colorectal cancer

Colorectal cancer constitute the third most common cancer in the Western world. Their incidence constantly increases as the population ages, and despite recent advances in colorectal cancer therapy, the cancer metastasizes in every third of colorectal cancer patients, and a significant part of these patients eventually die from the disease

Study: Pleotropic drugs can have both favorable and unfavorable effects on cell growth, survival

The cover for issue 37 of Oncotarget features Figure 7, "The combination of romidepsin and KU60019 is synergistic in a xenograft model of MCL," by Scotto, et al. which reported that the antiproliferative effect induced by histone deactylase inhibitors is associated with the up-regulated expression of the cyclin-dependent kinase inhibitor p21.

SARS-CoV-2 with D614G mutation is prevalent in central India

A team of scientists at the Defence Research and Development Establishment, India, reveals that there are multiple viral introduction events in central India, and SARS-CoV-2 with D614G mutation is the prevalently circulating strain.

Study provides insight into lymphomagenesis and patterns of resistance to immunotherapy

Lymphomas are a diverse group of cancers of the immune system, which is the body's primary defense against autoimmune disease, infections, and malignancy.

New antitumor vaccines control melanoma growth in preclinical models

Combining their expertise in protein engineering and synthetic DNA technology, scientists at The Wistar Institute successfully delivered nanoparticle antitumor vaccines that stimulated robust CD8 T cell immunity and controlled melanoma growth in preclinical models.

DLnano-vaccines may be a promising strategy for cancer immunotherapy

Researchers designed DLnano-vaccines displaying 60 copies of protein parts derived from the melanoma-specific antigens Trp2 and Gp100 and tested these in mouse models of melanoma, observing prolonged survival that depended on CD8 T cell activation both in therapeutic and prophylactic settings.

Researchers identify proinflammatory lipids that precede onset of Type 1 diabetes in mouse model, children

Type 1 diabetes, or T1D, is an autoimmune disease in which the body's immune cells - led by inflammatory macrophages - attack and destroy the beta cells of the pancreas that produce insulin.

Host gene editing main driving force of SARS-CoV-2 mutations

A new study published on the aRxiv preprint server in September 2020 shows that the host immune response, mediated by two RNA editors, causes the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to adapt and change strain characteristics.

Antibody-mediated platelet death linked to COVID-19 severity

A new study by University of Tuebingen researchers shows the strong association between platelet apoptosis and the thrombotic manifestations that may underlie critical COVID-19 illness.

Study: BIRC2 overexpression could be a key marker for immunotherapy resistance

Johns Hopkins Medicine researchers have added to evidence that a gene responsible for turning off a cell's natural "suicide" signals may also be the culprit in making breast cancer and melanoma cells resistant to therapies that use the immune system to fight cancer.

Evidence of SARS-CoV-2 coronavirus particles in heart tissue

Researchers in Milan, Italy, have identified the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the heart tissue of deceased coronavirus disease 2019 (COVID-19) patients who had died from respiratory failure, without showing any signs of cardiac involvement.

Identifying COVID-19 host genes using symptom-based predictions

A recent study published on the preprint server bioRxiv* in August 2020 shows that symptom-based prediction of the diagnosis can help identify host genes that are responsible for part of this variability.

Bioinformatics identifies key genes and cellular pathways in COVID-19

The COVID-19 pandemic is showing no signs of waning or extinction anytime soon. Now, a new study published on the preprint server bioRxiv* in August 2020 shows a new bioinformatics approach to studying the pathogenesis of this disease, by uncovering the differentially expressed genes (DEGs) and cell signaling pathways that cause the disease characteristics. This will help develop better therapies to counter the effects of these genes.

Study reveals bacteria's secret weapon to evade immune responses

Monash Biomedicine Discovery Institute scientists have discovered a previously unknown method used by bacteria to evade immune responses.

ARDS may not be the primary lung iInjury in COVID-19

A new Italian study published on the preprint server medRxiv in August 2020 shows that this may not be an adequate explanation, since ARDS is a nonspecific diagnosis. Instead, they say, antemortem lung biopsy shows a “Covid pattern” of acute lung injury, which could guide the application of therapeutics.
