BACKGROUND Severe sepsis and septic shock are major causes of morbidity and mortality worldwide. In experimental sepsis there is prominent apoptosis of various cell types, and genetic manipulation of death and survival pathways has been shown to modulate organ injury and survival. METHODOLOGY/PRINCIPAL FINDINGS We investigated the effect of extracellular administration of two anti-apoptotic m...

PURPOSE To explore the possible intermediary pathways through which diabetes mellitus (DM) adversely worsens hepatocellular carcinoma (HCC), focusing on cell life controllers as some transcription factors and inflammatory mediators. MATERIAL AND METHODS Forty male albino rats were divided into four groups, control, cancer [given single intra-peritoneal (IP) dose of diethyl nitrosamine, NDEA, ...

Dual IgH/BCL2 and BCL6 translocations are rarely observed in B-cell non-Hodgkin lymphomas (B-NHLs). We investigated the morphologic, phenotypic, and cytogenetic spectrum of B-NHL with such dual translocations. Dual IgH/BCL2 and BCL6 translocations were detected in follicular lymphomas (FLs) and diffuse large B-cell lymphomas (DLBCLs), representing 6.1% of 132 B-NHLs in our series, including 6 (...

By real-time quantitative polymerase chain reaction (RQ-PCR), we evaluated BCL2/IgH(+) cells in the bone marrow (BM) and peripheral blood (PB) from 86 patients with follicular lymphoma treated with the sequential administration of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) and rituximab. At diagnosis, the amount of BCL2/IgH(+) cells in the BM was low (1 BCL2/IgH(+) cell i...

Small-cell lung cancer (SCLC) tumours are highly aggressive. At the time of diagnosis, patients have often developed metastases, and overall prognosis is particularly poor, making effective treatment difficult. Novel mechanisms need to be identified as treatment targets. We have previously found low levels of the glucocorticoid receptor (GR) in SCLC cell lines and demonstrated that over-express...

Programmed cell death or apoptosis is a prominent feature of low-risk myelodysplastic syndromes (MDS), although the underlying mechanism remains controversial. High-risk MDS have less apoptosis associated with increased expression of the prosurvival BCL2-related proteins. To address the mechanism and pathogenic role of apoptosis and BCL2 expression in MDS, we used a mouse model resembling human...

Viability-promoting genes such as BCL2 play an important role in human cancer but do not directly cause aggressive tumors. BCL2 transgenic mice develop lymphoma at low frequency, hindering studies of tumorigenesis and its inhibition in the presence of such gene products. MCL1 is a member of the BCL2 family that is highly regulated endogenously and that promotes cell viability and immortalizatio...

s were prepared by the authors and printed as submitted. T H U R S D A Y, JU N E 2, 2016 was carried out in the third group (DM-EX group) for four weeks. The animals were sacrificed; the blood were collected; the blood glucose was measured; the autophagy relationship proteins (i.e., Atg5, LC3-I, LC3-II, Atg12) and apoptosis proteins (i.e., Beclin1, caspase3, cleaved caspase3, Bcl2, P-Bcl2) were...

To examine the role of apoptosis in neuromuscular disease progression, we have determined whether pathogenesis in dystrophin-deficient (mdx) and laminin alpha2-deficient (Lama2-null) mice is ameliorated by overexpression of the anti-apoptosis protein BCL2 in diseased muscles. The mdx mice are a model for the human disease, Duchenne muscular dystrophy (DMD), and the Lama2-null mice are a model f...

Hepatoblastoma, the most common type of pediatric liver cancer, is treated with a combination of surgery and chemotherapy. An essential drug in the treatment of hepatoblastoma is doxorubicin, which in high doses is cardiotoxic. This adverse effect is due to downregulation of cardiac expression of transcription factor GATA4, leading in turn to diminished levels of anti-apoptotic BCL2 (B-cell lym...
