Open AccessMining of a streptothricin gene cluster from Streptomyces sp. TP-A0356 genome via heterologous expression
Streptothricins (STs) are used commercially to treat bacterial and fungal diseases in agriculture. Mining of the sequenced microbial genomes uncovered two cryptic ST clusters from Streptomyces sp. C and Streptomy...

Open Access1-Methyl-tryptophan attenuates regulatory T cells differentiation due to the inhibition of estrogen-IDO1-MRC2 axis in endometriosis
Foxp3+ regulatory T (Treg) cells contribute to the local dysfunctional immune environment in endometriosis, an estrogen-dependent gynecological disease, which affects the function of ectopic endometrial tissue cl...

Open AccessEmetine inhibits Zika and Ebola virus infections through two molecular mechanisms: inhibiting viral replication and decreasing viral entry
The re-emergence of Zika virus (ZIKV) and Ebola virus (EBOV) poses serious and continued threats to the global public health. Effective therapeutics for these maladies is an unmet need. Here, we show that emet...

Biological activity-based modeling identifies antiviral leads against SARS-CoV-2
Computational approaches for drug discovery, such as quantitative structure–activity relationship, rely on structural similarities of small molecules to infer biological activity but are often limited to ident...

Open AccessDistribution, characterization, and antibiotic resistance of hypervirulent Klebsiella pneumoniae isolates in a Chinese population with asymptomatic bacteriuria
Asymptomatic bacteriuria (ASB) frequently occurs among all ages and may develop into urinary tract infections (UTIs). Hypervirulent Klebsiella pneumoniae (hvKP) has become a new threat to human health. In our stu...

Open AccessEmergence of polymyxin B-heteroresistant hypervirulent Klebsiella pneumoniae from an individual in the community with asymptomatic bacteriuria
The heteroresistance of polymyxin B, a last-resort antibiotic used to treat many serious bacterial infections, may lead to antibiotic treatment failure. However, polymyxin B-heteroresistant isolates are rare i...

Dynamic evolution of small signalling peptide compensation in plant stem cell control
Gene duplications are a hallmark of plant genome evolution and a foundation for genetic interactions that shape phenotypic diversity1–5. Compensation is a major form of paralogue interaction6–8 but how compensati...

Open AccessClonal transmission of polymyxin B-resistant hypervirulent Klebsiella pneumoniae isolates coharboring blaNDM-1 and blaKPC-2 in a tertiary hospital in China
The prevalence of multidrug-resistant hypervirulent K. pneumoniae (MDR-hvKP) has gradually increased. It poses a severe threat to human health. However, polymyxin-resistant hvKP is rare. Here, we collected eight ...
