CCND1 and infection: Through qRT-PCR we recorded an elevated expression of the cyclin D1 gene (ccnd1) in infection-III and -IV at 12 and 24 h compared to samples treated with individual pathogens (infection-I and -II) (Fig. 5A), while we witnessed a significantly lower expression of ccnd1 at 48 h in infection-III and -IV compared to infection strategies I and II (Fig. 5A).
