Influence of Biphasic Stimulation on Olfactory Ensheathing Cells for Neuroprosthetic Devices [PDF]

, 2016
The recent success of olfactory ensheathing cell (OEC) assisted regeneration of injured spinal cord has seen a rising interest in the use of these cells in tissue-engineered systems.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

FEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

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.

Hypoxia inducible factors regulate pluripotency and proliferation in human embryonic stem cells cultured at reduced oxygen tensions

Reproduction, 2010
Human embryonic stem (hES) cells are routinely cultured under atmospheric, 20% oxygen tensions but are derived from embryos which reside in a 3–5% oxygen (hypoxic) environment. Maintenance of oxygen homeostasis is critical to ensure sufficient levels for

The role of interleukin 12 and nitric oxide in the development of spontaneous autoimmune disease in MRL/MP-lpr/lpr mice [PDF]

, 1996
MRL/MP-lpr/lpr (MRL/lpr) mice develop a spontaneous autoimmune disease. Serum from these mice contained significantly higher concentrations of nitrite/nitrate than serum from age-matched control MRL/MP-+/+ (MRL/+), BALB/c or CBA/6J mice.

MET variants with activating N‐lobe mutations identified in hereditary papillary renal cell carcinomas still require ligand stimulation

Molecular Oncology, EarlyView.
MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for

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.

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

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 ...

Peripheral blood proteome biomarkers distinguish immunosuppressive features of cancer progression

Molecular Oncology, EarlyView.
Immune status significantly influences cancer progression. This study used plasma proteomics to analyze benign 67NR and malignant 4T1 breast tumor models at early and late tumor stages. Immune‐related proteins–osteopontin (Spp1), lactotransferrin (Ltf), calreticulin (Calr) and peroxiredoxin 2 (Prdx2)–were associated with systemic myeloid‐derived ...
