1. The Protective Effect of Kaempferol Against Ischemia/Reperfusion Injury Through Activating SIRT3 to Inhibit Oxidative Stress
Abstract Introduction: The objective of this study is to investigate the protective effect of kaempferol against ischemia/reperfusion (IR) injury and the underlying molecular mechanisms. Methods: H9C2 cells were pretreated with kaempferol for 24 hours and further insulted with IR injury. Cell vitality, reactive oxygen species (ROS) level, glutathione (GSH)

2. Protective roles of Pyracantha fortuneana extract on acute renal toxicity induced by cadmium chloride in rats
Abstract Purpose: To investigate the protective roles of pyracantha fortune fruit extract (PFE) on acute renal toxicity induced by cadmium chloride (CdCl2) in rats. Methods: Rats were pretreated with PFE and consecutively injected with CdCl2 (6.5 mg/kg) for 5 days. Results: The concentration of Cd, kidney weight, malondialdehyde (MDA), and nitric oxide (N

3. Protective effect of crocetin from Crocus sativus L. on myocardial ischemia-reperfusion injury in rats
Abstract This study investigated the protective effect of crocetin from Crocus sativus L. on myocardial ischemia-reperfusion injury (MIRI) in rats. Sixty SD rats were randomly divided into sham-operated, model, and low-, medium- and high-dose crocetin groups. Later 3 groups were intragastrically administrated with 10, 20 and 40 mg/kg crocetin from Crocus sat

4. A expressão imuno-histoquímica das proteínas p53, BCL-2, BAX e VEGFR1 em nefroblastomas
INTRODUÇÃO: O nefroblastoma, ou tumor de Wilms, é a neoplasia renal mais frequente na infância. Embora o prognóstico seja favorável para a maioria dos pacientes, muitos evoluem para recidiva ou óbito. A caracterização de grupos de risco por meio de marcadores imuno-histoquímicos tem por objetivo adequar o tratamento ao grupo de risco e reduzir reci

5. Imunoexpressão de biomarcadores do ciclo celular em amostras de neuroblastomas e sua relação com fatores prognósticos
INTRODUÇÃO: Sabe-se que os níveis de expressão de moléculas envolvidas na regulação da apoptose e da proliferação celular apresentam valor prognóstico em pacientes com neuroblastomas. OBJETIVO: Avaliar a imunoexpressão das proteínas Ki67, B-cell lymphoma 2 (BCL-2), phosphatase and tensin homolog (PTEN), caspase-8 e BCL-2 associated protein X (BAX

6. Apoptose e modelos in vivo para estudo das moléculas relacionadas a este fenômeno
RESUMO A apoptose, ou morte celular programada, é um processo fisiológico essencial para a eliminação de células em excesso ou que não são mais necessárias ao organismo, atuando na homeostase dos tecidos; entretanto, esse fenômeno também está envolvido em condições patológicas. A apoptose promove a ativação de vias bioquímicas dentro das cé

7. Expressão dos genes relacionados à apoptose, Bcl-2, bax, e caspase-3 nos adenomas hipofisários clinicamente não funcionantes e seu potencial como marcador do comportamento tumoral / Bcl-2, bax and caspase-3 apoptosis related genes expression in nonfunctioning pituitary adenoma and their role as potential markers of tumor behavior
Pituitary adenomas are benign, slow-growing tumors that arise in the sella turcica and account for 10% to 15% of all intracranial tumors. Non-functioning pituitary adenomas (NFPA) account for around one third of all pituitary adenomas. NFPA do not clinically present as hormonal syndromes and are generally diagnosed as macroadenomas due to marked neurological

8. Caracterização da DNase da peçonha da serpente Bothrops alternatus : comparação com a DNase acida de mamiferos envolvida em apoptose / Characterization of a Dnase from Bothrops alternatus snake venom : comparision with mamalian acid Dnases involved in apoptosis
Bothrops snake venoms are cytotoxic to a variety of cells (endothelial, smooth muscle, renal and inflammatory cells), and may cause cell death by apoptosis. The venom components implicated in apoptosis include metalloproteinases and L-amino acid oxidase. In contrast, although acidic deoxyribonucleases (DNase II) have been implicated in DNA fragmentation duri

9. The effect of tyrosine-kinase inhibitors on the apoptosis machinery in chronic myeloid leukemia / Efeitos dos inibidores de tirosina-quinase sobre a maquinaria apoptótica na leucemia mielóide crônica
Chronic myeloid leukemia (CML) is a myeloproliferative disease resultant of a clonal expansion of pluripotent hematopoietic stem cells. The CML physiopathology is associated with a translocation between chromosomes 9 and 22 long arms, promoting the formation of a bcr-abl neogene, which codifies the Bcr-Abl protein. The Bcr-Abl oncoprotein presents tyrosine-k

10. Expressão das proteínas BCL-2 e BAX em tumores astrocíticos humanos
INTRODUÇÃO: Os astrocitomas constituem os mais freqüentes tumores primários do sistema nervoso central (SNC). Admite-se que parte do crescimento tumoral seja resultante da inibição da morte celular programada: a apoptose. Tal fenômeno é basicamente regulado pelo equilíbrio entre moléculas antiapoptóticas (ex.: B-cell lymphoma protein 2 [BCL-2]) e

11. The Gene That Encodes the Herpes Simplex Virus Type 1 Latency-Associated Transcript Influences the Accumulation of Transcripts (Bcl-xL and Bcl-xS) That Encode Apoptotic Regulatory Proteins
The herpes simplex virus type 1 latency-associated transcript (LAT) inhibits apoptosis. We demonstrate here that LAT influences the accumulation of the Bcl-xL transcript versus the Bcl-xS transcript in Neuro-2A cells. Bcl-xL encodes an antiapoptotic protein, whereas Bcl-xS encodes a proapoptotic protein. Promoting the accumulation of Bcl-xL in neurons may in

12. Constitutive association of the proapoptotic protein Bim with Bcl-2-related proteins on mitochondria in T cells
Apoptosis in activated T cells in vivo requires the proapoptotic Bcl-2 family member Bim. We show here that, despite its ability to bind LC8, a component of the microtubule dynein motor complex, most of the Bim in both healthy and apoptotic T cells is associated with mitochondria, not microtubules. In healthy resting T cells Bim is bound to the antiapoptotic
