Preclinical Efficacy and Proteomic Prediction of Molecular Targets for s-cal14.1b and s-cal14.2b Conotoxins with Antitumor Capacity in Xenografts of Malignant Pleural Mesothelioma.

Malignant pleural mesothelioma (MPM) is a rare neoplasm with increasing incidence and mortality rates. Although recent advances have improved the overall prognosis, they have not had an important impact on survival of patients with MPM, such that more effective treatments are needed. Some species of marine snails have been demonstrated to be potential sources of novel anticancer molecules.

Complete Genome Sequence of Halopseudomonas aestusnigri Strain GOM5, Isolated from Asphalt Marine Sediments of the Gulf of Mexico.

We report here the complete genome sequence of a marine Halopseudomonas aestusnigri strain isolated from asphalt sediments of the Gulf of Mexico. Studying the genomes of atypical environmental bacteria increases knowledge about the biology of microorganisms metabolizing pollutants and is also a biotechnological resource to develop bioremediation methods.

Characterization of Enterobacter cloacae BAGM01 Producing a Thermostable and Alkaline-Tolerant Rhamnolipid Biosurfactant from the Gulf of Mexico.

The search for novel biosurfactants (Bs) requires the isolation of microorganisms from different environments. The Gulf of Mexico (GoM) is a geographical area active in the exploration and exploitation of hydrocarbons. Recent metagenomic and microbiologic studies in this area suggested a potential richness for novel Bs microbial producers.

Microbial prospection of communities that produce biosurfactants from the water column and sediments of the Gulf of Mexico.

Microbial communities capable of hydrocarbon degradation linked to biosurfactant (BS) and bioemulsifier (BE) production are basically unexplored in the Gulf of México (GOM). In this work, the BS and BE production of culturable marine bacterial hydrocarbonoclasts consortia isolated from two sites (the Perdido Fold Belt and Coatzacoalcos area) was investigated. The prospection at different locations and depths led to the screening and isolation of a wide variety of bacterial consortia with BS and BE activities, after culture enrichment with crude oil and glycerol as the carbon sources.

Whole-genome comparison between reference sequences and oyster Vibrio vulnificus C-genotype strains.

Whole-genome sequences of Vibrio vulnificus clinical genotype (C-genotype) from the CICESE Culture Collection, isolated from oysters, were compared with reference sequences of CMCP6 and YJ016 V. vulnificus C-genotype strains of clinical origin. The RAST web server estimated the whole genome to be ~4.

Bacterial Diversity and the Geochemical Landscape in the Southwestern Gulf of Mexico.

Marine sediments are an example of one of the most complex microbial habitats. These bacterial communities play an important role in several biogeochemical cycles in the marine ecosystem. In particular, the Gulf of Mexico has a ubiquitous concentration of hydrocarbons in its sediments, representing a very interesting niche to explore.

Genetic Analysis of Vibrio parahaemolyticus O3:K6 Strains That Have Been Isolated in Mexico Since 1998.

Vibrio parahaemolyticus is an important human pathogen that has been isolated worldwide from clinical cases, most of which have been associated with seafood consumption. Environmental and clinical toxigenic strains of V. parahaemolyticus that were isolated in Mexico from 1998 to 2012, including those from the only outbreak that has been reported in this country, were characterized genetically to assess the presence of the O3:K6 pandemic clone, and their genetic relationship to strains that are related to the pandemic clonal complex (CC3).

Technological Evolution in the Development of Therapeutic Antibodies.

Immunotherapy is defined as the use of the immune system or components of it, such as key immune molecules, to fight diseases or invading infectious agents. Modern biotechnology provides industrial versions of immune molecules (components of the immune system) naturally produced by the human body. Immune molecules such as monoclonal antibodies are used as therapeutics in several disease conditions.

Anti-tumor necrosis factor VNAR single domains reduce lethality and regulate underlying inflammatory response in a murine model of endotoxic shock.

Background: In sepsis, tumor necrosis factor (TNF) is the key factor triggering respiratory burst, tissue injury and disseminated coagulation. Anti-TNF strategies based on monoclonal antibodies or F(ab')₂ fragments have been used in sepsis with contradictory results. Immunoglobulin new antigen receptors (IgNAR) are a unique subset of antibodies consisting of five constant (CNAR) and one variable domains (VNAR).
