i-Fect Delivers circRNA and miRNA

Blocks Bone Cancer Pain
Altered expression of circular RNA (circRNA) is recognized as a contributor to malignant pain where microRNA (miRNA) exerts an essential effect. Researchers used our i-FectTMTransfection Kit to knock them down. Zhongqi Zhang, Xiaoxia Zhang, Yanjing Zhang, Jiyuan Li, Zumin Xing. Yiwen Zhang. Spinal circRNA-9119 Suppresses Nociception by Mediating the miR-26a-TLR3 Axis in a Bone Cancer Pain Mouse Model. Spinal circRNA-9119 Suppresses Nociception by Mediating the miR-26a-TLR3 Axis in a Bone Cancer Pain Mouse Model. Journal of Molecular Neuroscience. pp 1–10

Intrathecal Administration of miRNA and circRNA Pre-miRNA sequence of miR-26a and circ9119 were cloned into a plasmid. The i-Fect transfection reagent (10 μL; Neuromics, Edina, USA) was used to resuspend plasmids for injection.

More on Epigenetics and Pain

Great Research Tools!

Our Markers and i-FectTM  Transection Kit are  used to study Epigenetics and pain. Here's yet another example: M. Leinders, b, N. Üçeyler, R.A. Pritchard, C. Sommer, L.S. Sorkin. Increased miR-132-3p expression is associated with chronic neuropathic pain. Experimental Neurology. Volume 283, Part A, September 2016, Pages 276–286...The inhibitor and mimetic were administered to awake rats via the it catheters. Prior to injection, active or mismatch inhibitors were mixed with (1:5 w/v) i-Fect™ in vivo transfection reagent(Neuromics, Edina, USA) to final doses of 5, 2 and 1 μg in 10 μl...

Spinal administration of miR-132-3p antagonists via intrathecal (i.t.) catheters dose dependently reversed mechanical allodyina  and eliminated pain behavior in the place escape avoidance paradigm (p < 0.001). Intrathecal administration of miR-132-3p mimetic dose-dependently induced pain behavior in naïve rats (p < 0.001). Taken together these results indicate a pro-nociceptive effect of miR-132-3p in chronic neuropathic pain.

Finding like these could pave the way for an miRNA like therapy for pain.
