[Molecular-genetic methods for diagnostics of tumour growth].

Considerable progress has recently been achieved in understanding molecular medicine in general and vell molecular biology in particular. Molecular medicine is a scientific discipline studying man under normal condition and pathological changes at the cellular-molecular level with reference to gene activity and function of protein mediators responsible for delivery of information to various organs or systems of the body and cell-to-cell interaction.

[Specific proteolysis of Clostridium thermocellum endoglucanase upon heterologous expression in Escherichia coli cells].

The cel(1) gene of Clostridium thermocellum encoding endoglucanase cloned earlier in Escherichia coli was deleted at specific sites and fused with the E. coli gene lacZ'. Analysis of heterologous expression of the produced variants was performed.
