Scientists map all yeast proteins across cell cycle for the first time

An international team led by researchers at the University of Toronto has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.

New study pinpoints mitochondria as key player in dietary fat-cancer connection

The research study is entitled "The Central Role of Mitochondria in the Relationship between Dietary Lipids and Cancer Progression". It revealed new findings on the factors that influence the development of diseases, such as the particularly interesting relationship between dietary fats and the development of cancer.

Different cellular building blocks are not produced at the same time, research shows

Textbooks will tell you that in dividing cells, the production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level.

Manuka honey could cure serious lung infections caused by drug-resistant bacterium

In a recent study published in the journal Microbiology, researchers demonstrated that incorporating Manuka honey into nebulized antibiotic treatment could effectively combat respiratory infections due to Mycobacterium abscessusus, offering a novel new therapeutic strategy for M. abscessus management.

Researchers challenge a popular scenario put forward to explain the arrival of the first eukaryotic organisms

In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the planet. Matters would remain largely unchanged in terms of evolutionary development in these so-called prokaryotic cells-;the bacteria and archaea-;for another billion and a half years.

A non-coding RNA molecule regulates mitochondrial gene expression in human cells, study shows

A new study published in the journal Cell shows that a non-coding RNA molecule regulates mitochondrial gene expression in human cells.

Researchers design and engineer artificial photosynthetic life-forms through endosymbiosis

Every plant, animal or other nucleus-containing cell also harbors an array of miniature "organs" that perform essential functions for the cell. In plants, for example, organelles called chloroplasts photosynthesize to generate energy for the organism.

Desipramine and L-cycloserine together reduce ceramide levels in the retina and enhance vision

Researchers from the University of California, Irvine have discovered that the absence of Adiponectin receptor 1 protein (AdipoR1), one of the principal enzymes regulating ceramide homeostasis in the retina, leads to an accumulation of ceramides in the retina, resulting in progressive photoreceptor cell death and ultimately vision loss.

Impact of BRCA1 mRNA expression on survival of patients breast and colorectal cancer

Oncotarget published "Opposing effects of BRCA1 mRNA expression on patient survival in breast and colorectal cancer and variations among African American, Asian, and younger patients" which reported that LMNB2 is a chromatin remodeling protein that also plays a role in eukaryotic cell proliferation by organizing the nuclear membrane during mitosis.

Finding potential microRNAs from humans and plants against SARS-CoV-2

A new study focuses on the identification of probable miRNA candidates from three medicinal plants.

Yeast cell machinery seamlessly 'reads' the unnatural ingredients in the genetic recipe

If the genome is the recipe of life, base pairs are the individual ingredients listed. These chemical structures form DNA, and every living organism on Earth has just four. The specific arrangements of these four base pairs -- A, T, C, G -- make us who and what we are.

Scientists reprogram a common bacterium to make designer sugar-based drug

Envisioning an animal-free drug supply, scientists have -; for the first time -; reprogrammed a common bacterium to make a designer polysaccharide molecule used in pharmaceuticals and nutraceuticals.

Process of molecular sorting emerges from combination of two spontaneous mechanisms, indicates study

The eukaryotic cell is the basic unit of animals and plants. At the microscope, it looks highly structured and subdivided in many membrane-bound compartments.

Glycylation essential to keep sperm swimming in a straight line, shows study

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells.

Pharmacophore model helps find key protease inhibitor responsible for COVID-19

A team of San Diego Supercomputer Center (SDSC) researchers recently created a pharmacophore model and conducted data mining of the database of drugs approved by the U.S. Federal Drug Administration (FDA) to find potential inhibitors of papain-like protease of SARS-CoV2, one of the main viral proteins responsible for COVID-19.

Researchers develop a deep learning-based algorithm for predicting sites of DNA methylation

A team of researchers from New Jersey Institute of Technology and Children's Hospital of Philadelphia have developed an algorithm through machine learning that helps predict sites of DNA methylation - a process that can change the activity of DNA without changing its overall structure - and could identify disease-causing mechanisms that would otherwise be missed by conventional screening methods.

UCLA scientists identify new function for histones

UCLA scientists have identified a new function for histones, the spool-shaped proteins that regulate gene expression and serve as anchors for strands of DNA to wrap around.

Examining the envelope protein of SARS-CoV-2

A new study by researchers at the University of Valencia and published on the preprint online server bioRxiv in May 2020 reports the topology of the envelope protein of the virus, which could contribute to a better understanding of how the virus interacts with other cell components and hopefully help to fight the disease better.

UChicago researchers reveal the secret of cancer-related Warburg effect

A new study, led by researchers at the University of Chicago, provides an answer to why cancer cells consume and use nutrients differently than their healthy counterparts and how that difference contributes to their survival and growth.

Sperm-egg fusion proteins are homologous to those used by Zika and Dengue viruses, research shows

The protein that helps the sperm and egg fuse together in sexual reproduction can also fuse regular cells together.
