Study: Inner nuclear envelope plays role in lipid metabolism

The cell nucleus is an organelle, in which the DNA of an organism is protected and duplicated. The nucleus of this organ-like structure in the cell plasma is surrounded by an outer and an inner nuclear envelope, which is penetrated by openings - so-called nuclear pores.

New studies on fat cell filling, history of biochemistry, and ketogenic diet

There's more than one type of fat cell. Besides the white fat that stores triglycerides in lipid droplets in preparation for lean times later, mammals also have heat-generating brown fat, which acts more like a radiator than a storage closet.

Researchers demonstrate new strategy for stimulating autophagy

Brown University researchers studying the biology of aging have demonstrated a new strategy for stimulating autophagy, the process by which cells rebuild themselves by recycling their own worn-out parts.

Study identifies critical role of protein in sperm tail development

The group led by ICREA Research Professor Cayetano Gonzalez at the Institute for Research in Biomedicine, in collaboration with Giuliano Callaini's team at the University of Siena in Italy, has published a study in The Journal of Cell Biology that identifies the critical role played by a protein called CENTROBIN in sperm tail development.

New studies use proteomics to shed light on pathogenic mechanisms

Recent studies in the journal Molecular & Cellular Proteomics have shed light on pathogenic mechanisms of the sexually-transmitted parasite Trichomonas vaginalis and the HIV-associated opportunistic lung fungus Aspergillus.

New discovery in cell biology can have implications for research into autoimmune diseases

Research carried out by the University has discovered the first data on an organelle that is really important in human cells in an ancient organism distantly related to humans.

Researchers succeed in integrating artificial organelles into cells of living organism

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of living zebrafish embryos.

Researchers discover key inner control mechanism of cell's 'smart glue'

Researchers at St. Jude Children's Research Hospital have discovered that a protein critical to a process called liquid-liquid phase separation within the cell undergoes internal changes in conformation that are key to its function.

Ribosomes found to be cause of somatic cell pluripotency

In 2012, a Japanese research group discovered that human skin cells acquire pluripotency when introduced to lactic acid bacteria. Now, the same group of researchers have found that the cause of somatic cell conversion into pluripotent stem cells is the ribosome, a protein synthesizing cellular organelle.

Viral replication process weak spot may help develop cure for infections

Researchers at the Morgridge Institute for Research believe they have identified a weak spot in the replication process of positive-strand RNA viruses, which could yield treatment for viral infections such as Zika, Polio, Chikungunya, Hepatitis C and even common cold viruses.

Scientists discover promising new target to fight a class of viruses

Scientists at the Morgridge Institute for Research have discovered a promising new target to fight a class of viruses responsible for health threats such as Zika, polio, dengue, SARS and hepatitis C.

Survival strategy of mRNAs during sugar deficiency in the cell

If a cell runs low on sugar, it stores certain messenger RNAs in order to prolong its life. As a research group at the Biozentrum of the University of Basel has now discovered, the protein Puf5p determines whether individual messenger RNAs will be stored or degraded when sugar levels are low.

Two studies show how cells adapt to stressors by reprogramming internal signaling networks

In a pair of publications, researchers have shown how cells adapt to stressors--like water loss--by reprogramming their internal signaling networks.

Scientists identify new strategies used by Helicobacter pylori to target mitochondria

Helicobacter pylori is a bacterial pathogen that colonizes the stomach of approximately half of the world's population. Infection with H. pylori is acquired in childhood and lasts for decades.

Researchers uncover promising targets for development of drugs against leishmaniasis

Brazilian researchers at the University of São Paulo's Bioscience Institute (IB-USP) are starting to unravel the molecular mechanisms by which the parasite that causes cutaneous leishmaniasis manages to circumvent the host organism's defenses and infect new cells.
