Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Cultured epidermal stem cells in regenerative medicine

Stem Cell Research & Therapy, 2017
Transplantation of cultured epidermal cell sheets (CES) has long been used to treat patients with burns, chronic wounds, and stable vitiligo. In patients with large area burns this can be a life-saving procedure. The ultimate goal, however, is to restore

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

FEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

Influence of polyamine analogue DENSPM on cell growth of human SNB19 glioblastoma cells

Chinese Journal of Contemporary Neurology and Neurosurgery, 2011
Objective To investigate the influence of polyamine analogue DENSPM (N1, N11-diethylnorspermine) on cell growth of human SNB19 glioblastoma cells. Methods DENSPM was added into the culture medium of SNB19 cells. MTS assay was used to assess cell survival

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

FEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

RC-IAL: linhagem celular contínua de rim de coelho - características e substrato para replicação de vírus

Revista de Saúde Pública
Uma linhagem celular de rim de coelho (denominada RC-IAL), que foi isolada em 1976, e que atualmente está na 150ª passagem, teve suas características analisadas. As células apresentaram morfologia semelhante aos fibroblastos desde o início de seu cultivo.

Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

FEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Identificação de micoplasmas pela inibição de crescimento de amostras isoladas de culturas celulares

Revista de Saúde Pública
As culturas celulares devem ser continuamente monitoradas quanto à presença de micoplasmas, pois, embora às vezes eles passem despercebidos, podem causar alterações cromossômicas, interferir na replicação viral, na produção de anticorpos e interferon.

Possible involvement of microtubules and microfilaments of the epididymal epithelial cells in 17beta-estradiol synthesis.

Folia Histochemica et Cytobiologica, 2004
The rat epididymal epithelial cells revealed features of steroidogenic cells and released 17beta-estradiol (E2) into the culture medium. In steroidogenic cells, elements of the cytoskeleton due to their influence on organelle distribution are implicated ...
