Bortezomib downregulates MGMT expression in T98G glioblastoma cells.

The efficacy of treatment for glioblastoma multiforme is currently limited by the development of resistance, particularly, but not exclusively, due to the expression of the DNA repair enzyme O6-methylguanine methyltransferase (MGMT) in a significant proportion of astrocytic tumors. MGMT is post-translationally regulated by the 26S proteasome, a multi-subunit organelle responsible for degradation of misfolded cellular proteins. The boronic acid dipeptide bortezomib is the first and only proteasome inhibitor in clinical use so far, and has been reported as a strategy to restrict growth and promote apoptosis of glioblastoma cells.

High rates of obesity prevalence in adults living in central Greece: data from the ARGOS study.

Objective: To investigate the prevalence of obesity in adults of a large region of Central Greece.

Design: The target group was adults aged 18 to 79 years who were residents of the region of Thessaly for at least one year. A sample of 852 individuals stratified for sex and age were included.

Additive inhibition of colorectal cancer cell lines by aspirin and bortezomib.

Purpose: To investigate the effect of cyclooxygenase-2 (Cox-2) inhibitor aspirin (acetylsalicylic acid, ASA) and proteasome inhibitor bortezomib in the proliferation and apoptosis of colorectal cancer cell lines.

Methods: MTT assay, trypan blue exclusion and DNA fragmentation have been used to investigate cell proliferation and apoptosis in the presence of drugs. For the determination of Cox activity a colorimetric method was used.

Abnormal expression of C3ORF9 gene in patients with myelodysplastic syndromes.

Myelodysplastic Syndrome (MDS) cells present genetic instability and dysregulation of the gene C3ORF9, which was isolated from an MDS cDNA library and codes for a putative protein. We studied the expression of C3ORF9 in MDS syndromes to contribute to the understanding of the pathophysiology of MDS. One hundred and thirty-one patients and 35 healthy controls were involved in our study.

Hematogenous spinal infection in central Greece.

Study Design: We retrospectively analyzed spinal infection (SpI), in a teaching Hospital, in Central Greece.

Objective: To study presentation, etiology, and outcome of SpI in Central Greece.

Summary Of Background Data: SpI most frequently involves the intervertebral disc and adjacent vertebral bodies and can cause neurologic impairment.
