Markers of oxidative stress have been found in spinal cord, cortex, cerebrospinal fluid, and plasma of SALS patients. Mitochondrial and calcium metabolism dysfunction were also found in peripheral lymphocytes from SALS patients. In this study, we demonstrate that lymphocytes from SALS patients are more prone to undergo alteration of cell membrane integrity(More)
Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative multifactorial disease characterized, like other diseases such as Alzheimer's disease (AD), Parkinson's disease (PD) or frontotemporal dementia (FTD), by the degeneration of specific neuronal cell populations. Motor neuron loss is distinctive of ALS. However, the causes of onset and progression of(More)
The identification of biological markers of Alzheimer's disease (AD) can be extremely useful to improve diagnostic accuracy and/or to monitor the efficacy of putative therapies. In this regard, peripheral cells may be of great importance, because of their easy accessibility. After subjects were grouped according to diagnosis, the expression of(More)
The bottom-up programming of living organisms to implement novel user-defined biological capabilities is one of the main goals of synthetic biology. Currently, a predominant problem connected with the construction of even simple synthetic biological systems is the unpredictability of the genetic circuitry when assembled and incorporated in living cells.(More)
46BR.1G1 cells derive from a patient with a genetic syndrome characterized by drastically reduced replicative DNA ligase I (LigI) activity and delayed joining of Okazaki fragments. Here we show that the replication defect in 46BR.1G1 cells results in the accumulation of both single-stranded and double-stranded DNA breaks. This is accompanied by(More)
Bromodeoxyuridine (BrdUrd) is a pyrimidine analogue which is incorporated into the DNA of proliferating cells. When in vivo BrdUrd infusion is coupled with bivariate flow cytometry to measure cell BrdUrd incorporation and DNA content, both the percentage of DNA-synthesizing cells [BrdUrd-labeling index (LI)] and the DNA synthesis time (TS) can be determined(More)
The discrimination of live/dead cells as well as the detection of apoptosis is a frequent need in many areas of experimental biology. Cell proliferation is linked to apoptosis and controlled by several genes. During the cell life, specific events can stimulate proliferation while others may trigger the apoptotic pathway. Very few methods (i.e. TUNEL) are(More)
Glioblastoma (GBL) is the most malignant brain tumour in adults, causing the death of most patients within 9-12 months of diagnosis. Treatment is based on a combination of surgery, radiation therapy, and chemotherapy. With these treatment modalities, however, responses are extremely poor, so identification of novel treatment strategies is highly warranted.(More)
Markers of oxidative and nitrosative stress have been found in spinal cord, cortex, cerebrospinal fluid and plasma of patients affected by amyotrophic lateral sclerosis (ALS), a fatal disorder characterised by progressive motor neuron degeneration. In this study, we investigated the effect of the NO-releasing agent, diethylamine NONOate (NONO), on(More)
Circulating endothelial cells (CECs) are associated with neoangiogenesis in various malignant disorders. Using flow cytometry, we studied CECs in 128 patients with myelodysplastic syndrome (MDS). MDS patients had higher CEC levels than controls (P<0.001), and an inverse relationship was found between CECs and international prognostic scoring system risk(More)
