Sentences with phrase «normal cellular proteins»

These diseases are thought to be caused by prions (pronounced pree - ons), infectious protein particles — normal cellular proteins that supposedly change their shape and then mold other protein molecules into the same sickly altered form.

Degenerative brain diseases like mad cow disease (officially known as bovine spongiform encephalopathy, or BSE), scrapie in sheep, and vCJD in humans are thought to be caused by prions, misfolded versions of a normal cellular protein called PrPC.

Allan Jacobson, Ph.D., of the University of Massachusetts Medical School and co-founder of PTC Therapeutics, the company that developed ataluren, and David Bedwell, Ph.D., professor of the UAB Department of Biochemistry and Molecular Genetics, have sought to understand precisely how ataluren allows the ribosome, the machinery of cellular protein synthesis, to skip over these inserted stop signs and produce proteins that have normal or near - normal function.

Calcium, however, puts a strain on cells — it is known to hinder protein - folding and metabolism when it accumulates — disrupting normal cellular function.

While normal RNA regulation involves regulated and reversible assembly of RNA - protein particles, both increased cellular age and mutation push the process towards hyperassembly, which leads to altered pools of RNA or RNA regulatory proteins in neurons that contribute to their eventual death.

However, this cellular intervention alters the normal expression of hypophosphorylated retinoblastoma (RB) protein needed for the expression of genes involved in cell functions [3] and, therefore, results in an abnormal cell.

In glaucoma, normal proteins (cellular machines) are corrupted and cause the retinal ganglion cells to die.

That way, even if the original genes in the mitochondrial are deleted, the backup copies will be able to supply the proteins needed to keep normal energy production going, allowing the cellular power plants to continue humming along normally and preventing them from entering into the toxic, mutant metabolic state.

Overexpression of fluorescently tagged proteins can lead to improper protein localization, protein aggregation, or disruption of normal protein function, and ultimately misinterpretation of the protein's cellular role.

Our hypothesis is that the centralized inhibitory control over the cellular protein quality control mechanisms has evolved to prevent their chronic activation which could be detrimental to metazoan growth and reproduction under normal conditions.
