Methylmalonic acid — an endogenous toxin?
Cellular and Molecular Life Sciences - Tập 62 - Trang 621-624 - 2005
S. Kölker, J. G. Okun
Methylmalonic acid was previously considered as major neurotoxin in methylmalonic acidurias. In contrast, recent studies support the notion that other metabolites deriving from propionyl-coenzyme A, inducing synergistic inhibition of mitochondrial energy metabolism, are more important than methylmalonic acid to understand the neuropathogenesis of this disease. However, it is not yet known whether ...... hiện toàn bộ

Disaccharidase rhythm in rat small intestine; no relationship with mitosis rhythm
Cellular and Molecular Life Sciences - Tập 34 - Trang 700-701 - 1978
Masayuki Saito, Masami Suda
Same circadian difference in the specific activities of sucrase and maltase was observed in the purified brush border fraction as in the crude homogenate of the mucosa of rat small intestine, suggesting that the disaccharidase rhythm is not due to the mitosis rhythm of epithelial cells.

Ctenidins: antimicrobial glycine-rich peptides from the hemocytes of the spider Cupiennius salei
Cellular and Molecular Life Sciences - Tập 67 - Trang 2787-2798 - 2010
Tommy Baumann, Urs Kämpfer, Stefan Schürch, Johann Schaller, Carlo Largiadèr, Wolfgang Nentwig, Lucia Kuhn-Nentwig
Three novel glycine-rich peptides, named ctenidin 1–3, with activity against the Gram-negative bacterium E. coli, were isolated and characterized from hemocytes of the spider Cupiennius salei. Ctenidins have a high glycine content (>70%), similarly to other glycine-rich peptides, the acanthoscurrins, from another spider, Acanthoscurria gomesiana. A combination of mass spectrometry, Edman degradati...... hiện toàn bộ
Vector-based RNA interference of cathepsin B1 in Schistosoma mansoni
Cellular and Molecular Life Sciences - Tập 67 - Trang 3739-3748 - 2010
Elissaveta B. Tchoubrieva, Poh C. Ong, Robert N. Pike, Paul J. Brindley, Bernd H. Kalinna
In helminth parasites, proteolytic enzymes have been implicated in facilitating host invasion, moulting, feeding, and evasion of the host immune response. These key functions render them potential targets for anti-parasite chemotherapy and immunotherapy. Schistosomes feed on host blood and the digested haemoglobin is their major source of amino acids. Haemoglobin digestion is essential for parasit...... hiện toàn bộ
Intracellular protein degradation in mammalian cells: recent developments
Cellular and Molecular Life Sciences - Tập 66 - Trang 2427-2443 - 2009
Erwin Knecht, Carmen Aguado, Jaime Cárcel, Inmaculada Esteban, Juan Miguel Esteve, Ghita Ghislat, José Félix Moruno, José Manuel Vidal, Rosana Sáez
In higher organisms, dietary proteins are broken down into amino acids within the digestive tract but outside the cells, which incorporate the resulting amino acids into their metabolism. However, under certain conditions, an organism loses more nitrogen than is assimilated in the diet. This additional loss was found in the past century to come from intracellular proteins and started an intensive ...... hiện toàn bộ
Plant ribosome-inactivating proteins type II induce the unfolded protein response in human cancer cells
Cellular and Molecular Life Sciences - Tập 68 - Trang 1269-1281 - 2010
C. Horrix, Z. Raviv, E. Flescher, C. Voss, M. R. Berger
Cytotoxic ribosome-inactivating proteins (RIPs) of type II such as ricin were investigated as anti-cancer agents, but also pose a threat as biological weapons. The molecular mechanism leading to their toxic effects is, however, not yet clear. The current paradigm, which states that the irreversible depurination of 28S rRNA results in a general translational arrest eventually leading to cell death,...... hiện toàn bộ
Cell density-dependent membrane distribution of ganglioside GM3 in melanoma cells
Cellular and Molecular Life Sciences - Tập 80 - Trang 1-15 - 2023

Kaneko, Yukinari Kato, Kei-ichiro Inamori, Jin-ichi Inokuchi, Yves Mély, Kazuhisa Iwabuchi, Toshihide Kobayashi
Monosialoganglioside GM3 is the simplest ganglioside involved in various cellular signaling. Cell surface distribution of GM3 is thought to be crucial for the function of GM3, but little is known about the cell surface GM3 distribution. It was shown that anti-GM3 monoclonal antibody binds to GM3 in sparse but not in confluent melanoma cells. Our model membrane study evidenced that monoclonal anti-...... hiện toàn bộ
