Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Approach for defining endogenous reference genes in gene expression experiments

open access: yesAnalytical Biochemistry, 2004
The quantification of gene expression by real-time polymerase chain reaction (PCR) has revolutionized the field of gene expression analysis. Due to its sensitivity and flexibility it is becoming the method of choice for many investigators. However, good normalization protocols still have to be implemented to facilitate data exchange and comparison.

Selection of reference genes for gene expression studies in astrocytomas

Analytical Biochemistry, 2011
This study was aimed to test a panel of six housekeeping genes (GAPDH, HPRT1, POLR2A, RPLP0, ACTB, and H3F) so as to identify and validate the most suitable reference genes for expression studies in astrocytomas. GAPDH was the most stable and HPRT1 was the least stable reference gene.

Identification of Stable Reference Genes for Toxicogenomic and Gene Expression Analysis

2021
Gene expression analysis has been becoming a popular method for studying gene function and response to different environmental stresses, including toxin/pollution exposure. Selection of a suitable reference gene is critically important for gene expression analysis due to that wrong reference genes will cause misleading and even wrong conclusion. A good

Validation of reference genes in the feline endometrium

Reproductive Biology, 2014
The aim of the study was to find the most stable reference genes from: ACTB, GAPDH, RPL30, CYC, RPL17, RPS7 and YWHAZ in the feline endometrium. Three free software packages, geNorm, NormFinder and BestKeeper were used. In geNorm analysis, the most stable gene was RPS7 (at a primer concentration 1000 nM) or YWHAZ (500 and 250 nM).

Candidate reference genes for gene expression studies in water lily

Analytical Biochemistry, 2010
The selection of an appropriate reference gene(s) is a prerequisite for the proper interpretation of quantitative Real-Time polymerase chain reaction data. We report the evaluation of eight candidate reference genes across various tissues and treatments in the water lily by the two software packages geNorm and NormFinder.
