Transcriptomic analysis reveals three important carbohydrate-active enzymes contributing to starch degradation of oleaginous yeast Lipomyces starkeyi.

The oleaginous yeast Lipomyces starkeyi has a high capacity for starch assimilation, but the genes involved and specific mechanisms in starch degradation remain unclear. This study aimed to identify the critical carbohydrate-active enzyme (CAZyme) genes contributing to starch degradation in L. starkeyi.

Identification and characterization of the suppressed lipid accumulation-related gene, SLA1, in the oleaginous yeast Lipomyces starkeyi.

The oleaginous yeast Lipomyces starkeyi is an attractive industrial yeast that can accumulate high amounts of intracellular lipids. Identification of genes involved in lipid accumulation contributes not only to elucidating the lipid accumulation mechanism but also to breeding industrially useful high lipid-producing strains. In this study, the suppressed lipid accumulation-related gene (SLA1) was identified as the causative gene of the sr22 mutant with decreased lipid productivity.

Asymptomatic hepatic pseudoaneurysm identified 25 days after knife injury: a case report.

Background: Hepatic pseudoaneurysm (HPA) is a rare complication that can occur after liver trauma and carries a high risk of rupture. HPA is usually asymptomatic until rupture, so performing routine surveillance of liver trauma patients is important. Most posttraumatic HPA occurs within the first week after injury, so surveillance imaging ~ 7 days postinjury is suggested.

Optimization of the CRISPR/Cas9 system using promoter derivatives in fission yeast.

The CRSIPR/Cas9 system has been applied to fission yeast, but there remain some rooms for improvement. Here we report that the weaker versions of the promoter, and promoters, for the potentially cytotoxic Cas9 achieved highly efficient mutagenesis and gene deletion at the locus. Employing a drug-selectable marker instead of conventional auxotrophic markers, our new vector system is compatible with a variety of experimental settings including prototrophic/auxotrophic strains and complete/minimal media.
