Improving AOX1 promoter efficiency by overexpression of Mit1 transcription factor.

Background: Reprogramming in transcriptional regulation provides an effective tool for adjusting cellular metabolic activities. The strong methanol-inducible alcohol oxidase-1 promoter (pAOX1) is commonly used for heterologous gene expression in the yeast Pichia pastoris. Here, we present a novel Pichia pastoris strain engineered to co-express methanol-induced transcription factor 1 (Mit1) and the target protein.

Infection is a disease that is mainly caused by different Gram-negative and Gram-positive bacteria. Treatment of infections requires a considerable amount of antibiotics, which can cause serious damage to the patient's body. Delivering the antibiotic only to the site of infection can prevent these destructive effects, such as the destruction of the normal intestinal flora.
