Published: 12 June 2024
...Shotaro Namba; Hisao Moriya ABSTRACT Although protein aggregation can cause cytotoxicity, such aggregates can also form to mitigate cytotoxicity from misfolded proteins, although the nature of these contrasting aggregates remains unclear. We previously found that overproduction (op) of a three...

... (also known as TP63 and TP73, respectively) protein in higher-grade tumor tissues. The data suggest p53 misfolding and/or aggregation, and subsequent amyloid formation, lead to loss of the tumor-suppressive function and the gain of oncogenic function, aggravation of which might determine the cancer...

Aggregates of misfolded prion protein (PrP), which appear in cells after exposure to the drug cyclosporin A (CsA), and disease-linked PrP mutants...

... of these proteins containing the expanded polyQ tract are thought to initiate aggregation and represent the toxic species. Although it is not clear how these toxic fragments are generated, in vitro data suggest that proteasomes are unable to digest polyQ tracts. To examine whether the resulting polyQ peptides could...

... that PSGL-1 binds to the C-terminal (G3 domain) of the extracellular proteoglycan PG-M/versican. Cells transfected with PSGL-1 or a shorter form containing the binding site, or cells expressing endogenous PSGL-1 aggregate in the presence of versican or G3 product. The aggregation appears to be induced by G3...

... to aggregate and these enlarged yolk platelets fill the cytoplasm of cpl-1 mutant embryos. Coincident with this aggregation is loss of fluorescence from a yolk green fluorescent protein (YP170::GFP). This suggests that loss of CPL-1 activity leads to aberrant processing and/or conformational changes in yolk...

... familial autosomal dominant Parkinson's disease. One explanation for the formation of perikaryal and neuritic aggregates of α-synuclein, which is a presynaptic protein, is that the mutations disrupt α-synuclein transport and lead to its proximal accumulation. We found that mutant forms of α-synuclein...

...F. Fasani; A. Bocquet; P. Robert; A. Peterson; J. Eyer Neurofilaments are synthesised and assembled in neuronal cell bodies, transported along axons and degraded at the synapse. However, in several pathological situations they aggregate in cell bodies or axons. To investigate their turnover when...

Moreover, a close correlation was observed between the fate of crosslinked proteins, including the TfR and acetylcholinesterase (AChE), and the fate of the clustered lipid N-Rh-PE. Thus antibody-induced aggregation of specific proteins like the TfR and AChE, which are normally sorted...

All of the lines showed levels of calcium-dependent aggregation that were similar to that of ELs8 cells and immunoblot analyses indicated that the amount of mouse E-cadherin expressed by several cells that did not show reduced invasion was comparable to that expressed...

The CD44Epican -transfected L cells acquired: (a) a selfaggregating phenotype that required hyaluronan but was calcium-independent; and (b) a new capacity to adhere to keratinocytes, a property that was blocked by an antiepican antibody. Both aggregation and adhesion of CD44Epican -transfected cells were...

Entry of S. typhimurium into HeLa epithelial cells produced extensive aggregation of cell surface class I MHC heavy chain, β 2 -microglobulin, fibronectin-receptor (α 5 β 1 integrin), and hyaluronate receptor (CD-44). Other cell surface proteins such as transferrin...
