The phrase "additionally analysed the expression" is correct and usable in written English.
It can be used when discussing further examination or evaluation of a particular expression or statement in a text or analysis.
Example: "In the study, the researchers additionally analysed the expression of various genes to understand their roles in the disease."
Alternatives: "further examined the expression" or "also evaluated the expression".
Additionally, the following set of primers was used to analyse the expression οf β-actin: sense 5′-GCTGCTCGTCGACAACGGCTC and antisense 5′-CAAACATGATCTGGGTCATCTTCTC-3′ (expected product 353 bp).
Additionally, we assessed whether fibroblasts exhibited differences in protein expression across different stages of malignant transformation by analysing the expression of the same proteins in fibroblasts surrounding benign glands (benign-associated fibroblasts; BAFs), PIN-associated fibroblasts (PAFs) and CAFs.
A subset of invasive breast cancer cases (n=150) was additionally analysed for protein level expression of the hypoxia-inducible (transcription) factors 1 α and 2 α (HIF-1 α, HIF-2 α), which are generally considered as the key regulators of the hypoxic response in cells and tissues, and their down stream targets GLUT1 and CAIX.
Additionally we also analysed the global gene expression patterns in yeast strains expressing individual Ssa proteins, using microarray and RT-qPCR analysis.
Expression of onfFN was additionally analysed by semiquantitative RT PCR and by quantitative fluorescence-based real-time PCR.
These results suggest that the AOX protein may be slightly increased by treatment of potato leaves with antimycin A. Since antibodies may vary in detecting different isoenzymes, gene expression of nda1 was additionally analysed at transcript level using a real-time PCR system.
Survival was additionally analysed using stratified Kaplan-Meier graphs and the log-rank test.
The occurrence of gastroenteritis was additionally analysed separately.
Additionally, we analysed the function of Ago2, which possesses catalytic activity for mRNA degradation, in spermatogenesis.
