As in many sub-Saharan African countries, the burden of malaria has been reduced in the Republic of Congo as a result of massive deployment of insecticide treated nets and availability of artemisinin-combinations therapies (ACTs). High to moderate genetic diversity of msp-1 gene of Plasmodium falciparum (P. falciparum) has been reported from different parts of the world but limited data are available from Central Africa including the Republic of Congo. For this reason, the aim of study was to investigate the P...

Glial cell line-derived neurotrophic factor (GDNF) exhibits potent neuroprotective properties in preclinical models of Parkinson's disease (PD), but challenges in GDNF delivery have been reported from clinical trials. To address this barrier, we developed a hematopoietic stem cell transplantation (HSCT) -based macrophage-mediated GDNF therapy platform. Here we introduced a regulatable lentiviral vector (LV-MSP-Tet-Off-hGDNF) in order to allow the expression of human GDNF to be adjusted or stopped by oral administration of doxycycline (Dox)...

Discrimination of highly pathogenic bacteria, such as Bacillus anthracis , from closely related species based on molecular biological methods is challenging. We applied Matrix Assisted Laser Desorption/Ionization-Time of Flight mass spectrometry (MALDI-TOF MS) to a collection of B. anthracis strains and close relatives in order to significantly improve the statistical confidence of identification results for this group of bacteria. Protein mass spectra of 189 verified and diverse Bacillus strains of the Bacillus cereus sensu lato group were generated using MALDI-TOF MS and subsequently analyzed with supervised and unsupervised statistical methods, such as shrinkage discriminant analysis (SDA) and principle component analysis (PCA)...

Alcoholism is a pervasive societal problem, yet available pharmacotherapies fail to treat most sufferers. The type 1 corticotropin-releasing factor (CRF1 ) receptor has received much attention for its putative role in the progression to alcohol dependence, although at present its success in clinical trials has been limited. Two single-nucleotide polymorphisms in the rat Crhr1 promoter have been identified in the Marchigian substrain of Sardinian alcohol-preferring (msP) rats. Unlike other Wistar-derived alcohol-preferring lines, nondependent msP rats reduce their alcohol self-administration in response to CRF1 antagonists and show increased brain CRF1 expression...

DNA methylation plays a decisive role in the regulation and control of gene expression. DNA methylation is a covalent modification, in which a methyl group is attached to the 5th carbon of the cytosine ring of a CpG dinucleotide that is located upstream from the promoter region of a gene. Promoter hypermethylation (gain of DNA methylation) of the p16 gene may cause silencing of gene expression and plays an important role in cancer. Therefore, detection of the methylation status of p16 gene is an important tool in epigenetic studies of various human cancers...

INTRODUCTION: Epigenetic modifications have been reported to play an important role in regulating gene expression and these modifications become critical when they have a role in controlling another important layer of epigenetic regulation namely microRNAs. In the present study, we have identified the microRNAs that may be regulated by promoter DNA methylation and histone acetylation in Human papilloma virus-positive head and neck squamous cell carcinoma. METHODOLOGY: HPV-negative cell line (UPCI:SCC-116) and HPV-16 +ve cell line (UPCI:SCC-090) were treated with methylation inhibitor (5-aza-2'-deoxycytidine, AZA) and acetylation inhibitor (Trichostatin-A, TSA), followed by micro-array analysis...

Despite adequate surgical resection, oral squamous cell carcinoma (OSCC) shows a high rate of recurrence and metastasis, which could be explained by the presence of molecular alterations in seemingly normal tumour margins and the entire oral mucosa. The aims of this study were (1) to assess the presence of gene amplification (c-Myc and HER2) and promoter methylation (p14 and p16) in the tumours, tumour margins, and unaffected oral mucosa of 40 OSCC patients, and (2) to evaluate the possibility of using these alterations as prognostic markers...

Drug resistance remains a major challenge in epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy. Bcl-2-like protein 11 (BIM), a B-cell lymphoma 2 family pro-apoptotic protein, is a prime target for specific anti-cancer therapeutics. However, the epigenetic regulation of BIM in non-small cell lung cancer (NSCLC) cell lines and patients with NSCLC in association with EGFR-TKI resistance requires investigation. Methylation-specific PCR (MSP), pyrosequencing, and nested quantitative (q)-MSP were conducted to explore the methylation status of BIM in NSCLC cell lines...
