Activating p53 with a Mutant-Specific Small Molecule.

is the most commonly mutated gene in cancer, but it remains recalcitrant to clinically meaningful therapeutic reactivation. We present here the discovery and characterization of a small molecule chemical inducer of proximity that activates mutant p53. We named this compound TRanscriptional Activator of p53 () due to its ability to engage mutant p53 and BRD4 in a ternary complex, which potently activates mutant p53 and triggers robust p53 target gene transcription.

Monoclonal antibodies against Vi antigen production and characterization.

As a result of fusion of in vitro immunized mouse splenocytes and myeloma Sp2/0 cells, stable hybridomas secreting monoclonal antibodies against Vi antigen were obtained. The monoclonal antibodies were of IgM class. Reactivity of monoclonal antibodies to Vi antigen of different origin was tested.

Characteristics of lactose-fermenting Salmonella strains from Poland.

In this study 184 lactose-fermenting Salmonella strains, collected in the National Salmonella Centre from the northern and central parts of Ponad were examined. Epidemiological, serological and biochemical investigations were carried out. Apart from this, chemotherapeutic resistance and male-phage sensitivity were determined.
