The adoption of agent technologies and multi-agent systems constitutes an emerging area in bioinformatics. In this article, we report on the activity of the Working Group on Agents in Bioinformatics (BIOAGENTS) founded during the first AgentLink III Technical Forum meeting on the 2nd of July, 2004, in Rome. The meeting provided an opportunity for seeding collaborations between the agent and bioinformatics communities to develop a different (agent-based) approach of computational frameworks both for data analysis and management in bioinformatics and for systems modelling and simulation in computational and systems biology. The collaborations gave rise to applications and integrated tools that we summarize and discuss in context of the state of the art in this area. We investigate on future challenges and argue that the field should still be explored from many perspectives ranging from bio-conceptual languages for agent-based simulation, to the definition of bio-ontology-based declarative languages to be used by information agents, and to the adoption of agents for computational grids.

MTHFD2 is highly overexpressed in breast cancer tissues, indicating that it might be used as a target in breast cancer treatment. This study aims to determine the role of MTHFD2 in breast cancer cell proliferation and the molecular pathways involved. In order to investigate MTHFD2 gene expression and its downstream pathways in breast cancer, we started our inquiry with a bioinformatics analysis.

Temozolomide kills cancer cells by forming O6-methylguanine (O6-MeG), which leads to cell cycle arrest and apoptosis. However, O6-MeG repair by O6-methylguanine-DNA methyltransferase (MGMT) contributes to drug resistance. Characterizing genomic profiles of O6-MeG could elucidate how O6-MeG accumulation is influenced by repair, but there are no methods to map genomic locations of O6-MeG.

Aptamers are short oligonucleotides that bind specifically to various ligands and are characterized by their low immunogenicity, thermostability, and ease of labeling. Many biomedical applications of aptamers as biosensors and drug delivery agents are currently being actively researched. Selective affinity selection with exponential ligand enrichment (SELEX) allows to discover aptamers for a specific target, but it only provides information about the sequence of aptamers; hence other approaches are used for determining aptamer structure, aptamer-ligand interactions and the mechanism of action.

Despite the importance of these post-translationally modified proteins for mycobacterial survival, many remain experimentally unconfirmed. Here we characterized metabolic incorporation of diverse fatty acid analogues as a facile method of adding chemical groups that enable downstream applications such as detection, crosslinking and enrichment, of not only lipid-modified proteins, but also their protein interactors.

1,4-Thiazepines (TZEPs) featuring enyne modifications represent promising candidates in cancer therapy. We synthesized novel TZEP derivatives and assessed their cytotoxicity, apoptosis induction, EGFR inhibition, and molecular interactions. TZEPs exhibited cytotoxic effects against cancer cell lines, with compounds TZEP6 and TZEP7 showing significant activity.
