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

Study resolves contradictions surrounding p53 gene's role in pluripotent stem cell differentiation

The gene p53 is extremely important in cell biology and, hence, the world of cell replacement therapy. Its role is to regulate the cell cycle and halt the formation of tumors, leading to its nickname the "tumor suppressor gene."

Rare deadly disease linked to coronavirus infection seen in children

Now, new evidence has shown that children with coronavirus disease (COVID-19) experience a Kawasaki-like illness, called multisystem inflammatory syndrome in children (MIS-C). The complication is akin to toxic shock syndrome, a condition that occurs due to sepsis. Though rare, the condition is life-threatening.

Capillary leakage important in COVID-19 respiratory distress

Now, a new study published on the preprint server medRxiv reports the pivotal role played by protein leakage through lung capillaries and promotes the use of serum albumin as a biomarker of disease progression and severity.

Certain corticosteroid could improve severe COVID-19, say researchers

Researchers at Wayne State University and Henry Ford Health System in Michigan have conducted a study indicating that the corticosteroid methylprednisolone could improve outcomes among patients with severe coronavirus disease 2019 (COVID-19).

Study shows how cancer protein changes may accelerate tumorigenesis and metastasis

Understanding the genetic mutations and protein changes that take place in the progression of cancer is key to its treatment. Mutations in the gene TP53 and concomitant mutant p53 proteins in cancer cells have become notorious over the course of multiple studies of several different types of cancers.

Novel insights on SARS-CoV-2 cell entry may inform further vaccine and treatment development

A research group from Harvard Medical School reported two cryo-electron microscopy structures derived from a single preparation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein in their paper available on the preprint server bioRxiv. Understanding the nuances of prefusion and postfusion conformations shed light on viral cell entry and may, in turn, guide the development of vaccines and drugs.

Researchers develop potential drug compound for treating cancer

Researchers at the University of Eastern Finland have developed a new and promising drug compound for the treatment of cancer that inhibits natural amino acids from entering cancer cells.

Abnormal calcium levels in mitochondria may cause neuronal cell death in Alzheimer's disease

For the first time, using a mouse model of Alzheimer's disease, scientists have documented a link between raised levels of calcium in mitochondria and neuronal death in the living brain.

No evidence COVID-19 is spread by fecal-oral transmission

A new study published on the preprint server medRxiv* in May 2020 shows that in patients who test positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pharyngeal and fecal samples, the virus persists longer in the fecal samples than in the pharyngeal samples. However, fecal-oral transmission does not appear to occur.

COVID-19 could accelerate activation of dormant tuberculosis (TB)

The ongoing COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has thrown much of the world into disarray, with over 4 million people reported infected and well over 282,000 deaths. A new study published on the preprint server bioRxiv in May 2020 suggests that the long-term impact of the virus could include activation of dormant bacterial infections like tuberculosis (TB).

Study demonstrates dynamic and broad-scale immune alterations in COVID-19 patient

A new case report released on the preprint server medRxiv* provides a detailed longitudinal analysis of the immune response associated with a fatal case of coronavirus disease (COVID-19). It highlights the need for addressing the source of hyper inflammation in the treatment approach.

HMGB1 protein may play a key role in pulmonary inflammation, tissue damage in severe COVID-19 cases

In severe cases of COVID-19, a massive release of the endogenous protein HMGB1 in the lungs may contribute to pulmonary inflammation and tissue damage, according to a review article published today in the scientific journal Molecular Medicine.

SARS-CoV-2 in wastewater and rivers

A new study published on the preprint server medRxiv in May 2020 shows that while the virus causing COVID-19 may be present in wastewater and rivers, the biological agent is typically devoid of vitality and unable to cause active infection. This should provide some relief to public health authorities in their quest to contain the virus.

SARS-CoV-2 genome shows mutation hotspots and type-specific distribution

Now, a new study published on the preprint server bioRxiv reports on a large scale analysis of SARS-CoV-2 genomes and reveals a clonal geo-distribution and rich genetic variations.

Uncovering immune cell reactions in COVID-19

A new study published on the preprint server medRxiv in April 2020 suggests that an overactive immune response is responsible for the more severe manifestations of the illness.

AI-based technology could help accelerate clinical trials for glaucoma

The technology, supported by an artificial intelligence (AI) algorithm, could help accelerate clinical trials, and eventually may be used in detection and diagnostics, according to the Wellcome-funded study published today in Expert Review of Molecular Diagnostics.

Research detects a more dangerous SARS-CoV-2 mutation

A new study published on the preprint server bioRxiv in May 2020 reports the setting up of a system to help track new mutations in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is behind the current COVID-19 pandemic. This will help analyze mutations to find and track the spread of those that are most likely to increase the pathogenicity of the virus, either by making it easier to transmit or by enhancing its resistance to treatment.

French scientists suggest nicotinic agonists could treat COVID-19

Contrary to the warnings issued by health agencies worldwide against cigarette smoking amid the coronavirus disease (COVID-19), a new paper suggests the possibility that nicotine, a component of tobacco, could prevent coronavirus infection.

Prolonged corticosteroid treatment increases adrenal gland inflammation

New research by academics at the University of Bristol has found evidence that prolonged treatment of synthetic corticosteroid drugs increases adrenal gland inflammation in response to bacterial infection, an effect that in the long-term can damage adrenal function.

Cannabidiol could be a useful therapy for difficult-to-treat brain cancer

Findings from a new study examining human and canine brain cancer cells suggest that cannabidiol could be a useful therapy for a difficult-to-treat brain cancer. Cannabidiol, or CBD, is a non-psychoactive chemical compound derived from marijuana.
