New model shows how dysfunction in the air sacs initiates fibrotic cascade

Idiopathic pulmonary fibrosis (IPF) is the most common and severe form of lung disease characterized by relentless scarring leading to death within an average of four years from the time of diagnosis.

Researchers show how a protein molecular motor can 'constrict' cell membranes

Cells in the human body constantly receive substances from the outside via a process called endocytosis. One important endocytosis pathway involves the formation of a protrusion within the cell membrane, pointing to the inside of the cell, triggered when a molecule needing to get in reaches the membrane.

Scientists identify small compounds that can regulate extracellular vesicle production

Biological vesicles are nano-sized containers that transport proteins and other substances within or between cells.

Researchers decipher genetic mechanisms governing the speed of protein synthesis

In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then translated into protein with the help of ribosomes, small machines capable of decoding messenger RNA to synthesise the appropriate proteins.

Researchers develop adult lung organoids that represent all cell types

Since the COVID-19 pandemic reached the United States in early 2020, scientists have struggled to find laboratory models of SARS-CoV-2 infection, the respiratory virus that causes COVID-19. Animal models fell short; attempts to grow adult human lungs have historically failed because not all of the cell types survived.

Research highlights the importance of meninges for brain development and pathology

A new study, led by researchers at the University of Gothenburg, have generated the first comprehensive transcriptional atlas of neonatal mouse meningeal leukocytes, under normal conditions and after perinatal brain injury.

New compounds offer a two-for-one punch to fight estrogen-sensitive breast cancer

A set of compounds developed by scientists at Scripps Research in Florida target estrogen-sensitive breast cancer cells in new ways, potentially creating better options for patients with treatment-resistant cancers.

Study identifies actionable genes and candidate drugs in biliary tract cancer using a knowledgebase

Oncotarget published "Actionability evaluation of biliary tract cancer by genome transcriptome analysis and Asian cancer knowledgebase" which reported that it is necessary to investigate actionable genes and candidate drugs using a sophisticated knowledgebase and characterize BTCs immunologically for evaluating the actionability of molecular and immune therapies.

DNMT2/TRDMT1 gene knockout may potentiate adverse effects related to drug-induced senescence

Aging-US published "The lack of functional DNMT2/TRDMT1 gene modulates cancer cell responses during drug-induced senescence" which reported that cellular senescence may be a side effect of chemotherapy and other anti-cancer treatments that may promote inflammation and paracrine secondary senescence in healthy tissues.

Study highlights the robustness of miRNA modulation during aging process

Aging-US published "miRNAs generated from Meg3-Mirg locus are downregulated during aging" which reported that Aging determines a multilevel functional decline and increases the risk for cardiovascular pathologies.

Mystery of roe deer embryonic diapause revealed

Everyone is familiar with the roe deer, either from crossword puzzles or from real-life encounters during a jog or a hike in the forest: majestic creatures with elegant big black eyes.

Research analyzes the role of RNA tags in Alzheimer’s disease

Understanding the role of tau protein in Alzheimer's disease (AD) has led to new ways to diagnose it as well as the creation of medicines now in clinical trials to treat it.

Researchers convert human stem cells into beta cells using small molecules

The human body can be genetically inclined to attack its own cells, destroying the beta cells in the pancreas that make insulin, which helps convert sugar into energy.

UZH and Airbus aim to grow three-dimensional organ-like tissues in microgravity

UZH Space Hub and Airbus Defence and Space are sending an experiment into space on the next resupply flight to the International Space Station (ISS) with the aim of advancing the industrial production of human tissue in microgravity.

Restoring DAXX protein levels may prevent misfolding of rogue proteins known to drive Alzheimer's

For the first time, Penn Medicine researchers showed how restoring levels of the protein DAXX and a large group of similar proteins prevents the misfolding of the rogue proteins known to drive Alzheimer's and other neurodegenerative diseases, as well as certain mutations that contribute to cancers.

Brain organoids provide a valuable model to study autism

Variations in the 16p11.2 region of the genome are associated with autism spectrum disorder. While people with genetic deletions in this region have larger heads (macrocephaly) and people with genetic duplications have smaller heads (microcephaly), both variation types affect brain development and function.

Stiffening of heart’s blood vessels associated with lack of enzyme that fosters cell ‘chatter’

In a study in mice, Johns Hopkins Medicine researchers have found that the smooth muscle cells lining the walls of blood vessels can lose their elasticity and lead to vascular stiffening, a condition that can precede heart disease and stroke.

Studies offer insight into how the human body develops and acquires mutations throughout life

New insights into how the human body develops from one cell into trillions, and the genetic mutations that cells pick up along the way, have been generated by two studies from scientists at the Wellcome Sanger Institute, the University of Cambridge and their collaborators.

Study unravels widespread tumor suppression mechanism that halts cancer metastasis

According to a study by The Wistar Institute, the tumor suppressor Parkin, whose levels are reduced in different cancer types, causes acute metabolic and oxidative stress, suppresses mitochondrial trafficking, and blocks tumor cell movement, reducing primary and metastatic tumor growth.
