TLR4 overexpression significantly reversed the effect of EX-miR-145-5p on inhibiting inflammatory response and activating TLR4/NF- κB pathway in PC12 cells
(a) ELISA was used to detect TNF-α expression in PC12 cells transfected with miR-145-5p mimic and TLR4 overexpression vector. (c) ELISA was used to detect IL-1β expression in PC12 cells transfected with miR-145-5p mimic and TLR4 overexpression vector. (c) ELISA was used to detect IL-6 expression in PC12 cells transfected with miR-145-5p mimic and TLR4 overexpression vector. (d) The expressions of p65 and IκBα were detected by qRT-PCR in PC12 cells transfected with miR-145-5p mimic and TLR4 overexpression vector. (e–h) The expressions of p65 and IκBα were detected by Western blot in PC12 cells transfected with miR-145-5p mimic and TLR4 overexpression vector.
