Azole effectiveness against candidiasis can be compromised by Candida albicans resistance and tolerance, and unfortunately, few clinically useful compounds can enhance azole antifungal activities. We find that the amino acids V234, F235 and L238 of Erg11 are critical for its interaction with Ncp1, and the Ncp1-Erg11 association is important in azole respo ...

The use of genetically modified nonconventional yeast provides significant potential for the bioeconomy by diversifying the tools available for the development of sustainable and novel products. In this study, we sequenced and annotated the genome of Kluyveromyces marxianus Y-1190 to establish it ...

In recent decades, the study of the opportunistic pathogenic fungus, Candida albicans, has been revolutionized by genomics, transforming our understanding of its molecular biology, pathogenicity, and modes of drug resistance. In this review, our effort is to trace the historical development of C. albicans research, from early clinical observations to mode ...

Candidiasis, which presents a substantial risk to human well-being, is frequently treated with azoles. However, drug-drug interactions caused by azoles inhibiting the human CYP3A4 enzyme, together with increasing resistance of Candida species to azoles, represent serious issues with this class of drug, making it imperative to develop innovative antifungal ...

Fluconazole (FLC) is extensively employed for the prophylaxis and treatment of invasive fungal infections (IFIs). However, the fungistatic nature of FLC renders pathogenic fungi capable of developing tolerance towards it. Consequently, converting FLC into a fungicidal agent using adjuvants assumes significance to circumvent FLC resistance and the perpetua ...

In the respiratory chain of the majority of aerobic organisms, the enzyme alternative oxidase (AOX) functions as the terminal oxidase and has important roles in maintaining metabolic and signaling homeostasis in mitochondria. AOX endows the respiratory system with flexibility in the coupling among the carbon metabolism pathway, electron transport chain (E ...

Fluconazole (FLC) tolerant phenotypes in Candida species contribute to persistent candidemia and the emergence of FLC resistance. Therefore, making FLC fungicidal and eliminating FLC tolerance are important for treating invasive fungal diseases (IFDs) caused by Candida species. However, the mechanisms of FLC tolerance in Candida species remain to be fully ...

Candida albicans, an opportunistic human pathogen, poses a significant threat to human health and is associated with significant socio-economic burden. Current antifungal treatments fail, at least in part, because C. albicans can initiate a strong drug tolerance response that allows some cells to ...

Transcription factors (TFs) play key roles in cellular regulation and are critical in the control of drug resistance in the fungal pathogen Candida albicans. We found that activation of the transcription factor C4_02500C_A (Adr1) conferred significant resistance against fluconazole. In Saccharomy ...

We report draft genome sequences for 15 non-conventional Saccharomycotina yeast strains obtained from public culture repositories. Included in our collection are eight strains of Pichia with broad tolerance to dicarboxylic acids. The genome sequences of these strains will enable comparative genomics of acid-tolerant phenotypes and strain engineering of no ...
