The terminal differentiation of epidermal keratinocytes requires transcriptional and posttranscriptional regulatory mechanisms. MicroRNAs (miRNAs) are small noncoding RNAs that play key roles during differentiation processes by regulating protein expression at the posttranscriptional level. Several studies have investigated miRNA expression in murine or human skin using northern blotting, microarrays, deep sequencing, or real-time PCR (Andl et al., Curr Biol 16:1041-1049, 2006; Hildebrand et al., J Invest Dermatol 131:20-29, 2011; Sonkoly et al., PLoS One 2:e610, 2007; Yi et al., Nat Genet 38:356-362, 2006; Yi et al., Proc Natl Acad Sci U S A 106:498-502, 2009). Conventional techniques such as northern blotting and microarrays often fail to detect miRNAs of low abundance, while the per-sample cost of deep sequencing approaches is still prohibitive in many cases. In contrast, stem loop primer-based real-time PCR methods for simultaneous detection of up to 380 miRNAs allow fast, specific, and reliable miRNA profiling. These methods are suitable for in vitro material, but also for samples which are of limited availability, such as epidermal stem cells isolated from human skin biopsies. Here, we describe a general real-time PCR method for miRNA profiling using isolated epidermal stem cells, transiently amplifying cells and terminally differentiated keratinocytes of human skin.

Introduction: Modification of natural enzymes to introduce new properties and enhance existing ones is a central challenge in bioengineering. This study is focused on the development of Taq polymerase mutants that show enhanced reverse transcriptase (RTase) activity while retaining other desirable properties such as fidelity, 5'- 3' exonuclease activity, effective deoxyuracyl incorporation, and tolerance to locked nucleic acid (LNA)-containing substrates. Our objective was to use AI-driven rational design combined with multiparametric wet-lab analysis to identify and validate Taq polymerase mutants with an optimal combination of these properties.

The mushroom is consumed worldwide and has high industrial value because of its rich content of bioactive compounds such as ergothioneine and eritadenine. Currently, mainstream artificial cultivation methods for this mushroom typically use synthetic logs. However, browning of the stem's interior (stem browning) has been observed during the cultivation in some strains.

Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic infectious disease caused by the CCHF virus, a member of the Bunyavirales order and the Orthonairoviridae family. The exact pathogenesis is not fully understood. Long noncoding RNAs (lncRNAs) are RNAs that are shown to play a role in various pathological processes of viral diseases.

Introduction: Acute coronary syndrome (ACS) patients undergoing primary percutaneous coronary intervention (PPCI) often experience the no-reflow phenomenon (NRP), characterized by reduced myocardial perfusion despite an open coronary artery. Adenosine, a potent vasodilator, is used to aid reperfusion. To elucidate underlying molecular mechanism of this phenomenon, we investigated expression of ADORA2A and ADORA2B genes, encoding adenosine receptors, in ACS patients with NRP and non-NRP.

Objective: To investigate the molecular typing characteristics, drug resistance status and drug resistance gene carrying of food-borne Staphylococcus aureus in Ningxia.
Methods: Staphylococcus aureus isolated from food safety risk monitoring project in Ningxia in the past ten years were collected, drug resistance was detected using microbroth dilution method, enterotoxins were detected by real-time PCR. The strains were genotyped by pulsed field gel electrophoresis(PFGE) using SmaI endonuclease.
