Apoptosis induced in hepatoblastoma HepG2 cells by the proteasome inhibitor MG132 is associated with hydrogen peroxide production, expression of Bcl-…

2002

This report is focused on the apoptotic effect induced by MG132, an inhibitor of 26S proteasome, in human hepatoma HepG2 cells. The results were compared with those obtained with non-transformed human Chang liver cells. MG132 reduced the viability of HepG2 cells in a time- and dose-dependent manner. The effect was in tight connection with the induction of apoptosis, as indicated by fluorescence microscopy and cytometric analysis, and was accompanied by a remarkable increase in the production of H2O2 and a reduction in mitochondrial transmembrane potential (Deltapsim). In addition cell death was prevented by antioxidants such as GSH, N-acetylcysteine or catalase. Western blot analysis showed…

Staurosporine-induced apoptosis in Chang liver cells is associated with down-regulation of Bcl-2 and Bcl-XL.

2004

A potent inhibitor of serine/threonine kinases, staurosporine exerts antiproliferative and apoptotic effects in many cancer cells, although the exact mechanism of its action is still unclear. This study examines the effects of staurosporine on Chang liver cells, an immortalized non-tumor cell line, in comparison with those caused in HuH-6 and HepG2 cells, two human hepatoma cell lines. Our results provide evidence that staurosporine promotes apoptosis in Chang liver cells as observed by flow cytometric analysis and acridine orange/ethidium bromide staining. The effect appeared already after 8 h of treatment and increased with treatment time and dose. After 48 h of exposure to 200 nM stauros…

The use of complementary alternative medicines in advanced cancer patients followed at home

2021

Objectives: To assess the use of complementary alternative medicines (CAM) in advanced cancer patients followed at home. Methods: A consecutive sample of advanced cancer patients admitted to a home palliative care program was invited to participate in the study in a period of two months. Demographic characteristics, religious belief, education level, diagnosis, and socio-economic condition were recorded. Patients were asked about the use of CAM, considered to be a health-related treatment practiced outside the established health services. Information about CAM indications and those who prescribed or suggested CAM were also collected. Results: Two hundred and eighty-three advanced cancer pat…

Epidemiology and Characteristics of Episodic Breathlessness in Advanced Cancer Patients. An Observational Study

2016

Abstract Context Episodic breathlessness is a relevant aspect in patients with advanced cancer. Objectives The aim of this study was to assess the different aspects of this clinical phenomenon. Methods A consecutive sample of patients with advanced cancer admitted to different settings for a period of six months was surveyed. The presence of background breathlessness and episodic breathlessness, their intensity (numerical scale 0–10), and drugs used for treatment were collected. Factors inducing episodic breathlessness and its influence on daily activities were investigated. Results Of 921 patients, 29.3% ( n  = 269) had breathlessness and 134 patients (49.8%) were receiving drugs for backg…
