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-Fect^TMTransfection 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.

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.

i-Fect Delivers Plasmids!

Important for Gene Expression Studies.
I have posted many examples of how our customers use i-Fect^TM  and other Transfection Solutions for Gene Manipulation Studies. There are also many publications.

Here we feature how i-Fect was used to delivery plasmids to the CNS: Sara Elramah, María José López-González, Matthieu Bastide, Florence Dixmérias, Olivier Roca-Lapirot, Anne-Cécile Wielanek-Bachelet, Anne Vital, Thierry Leste-Lasserre, Alexandre Brochard, Marc Landry & Alexandre Favereaux. Spinal miRNA-124 regulates synaptopodin and nociception in an animal model of bone cancer pain. Scientific Reports 7, Article number: 10949 (2017) doi:10.1038/s41598-017-10224-1...Intrathecal administration of miRNAs and ShRNA To over-express miR-124, we cloned the pre-miRNA sequence of miR-124 into a plasmid. To determine cells expressing this miR-124 encoding plasmid, we added a GFP-coding sequence to the construct under the control of an IRES. Thus, miR-124 over-expressing cells also express GFP. To inhibit synaptopodin expression, we cloned a ShRNA sequence directed against synaptopodin into a plasmid. To determine cells expressing this ShRNA, we added a GFP-coding sequence to the construct under the control of an IRES. Thus, ShRNA expressing cells also expressed GFP. Two micrograms of these plasmids or the corresponding controls, were solubilized in 10 µl of i-Fect reagent (Neuromics, Edina, USA), and injected intrathecally between the L5 and L6 lumbar vertebrae every two days for a total of 3 injections, according to the manufacturer’s instructions and previously published experiments...

Figures: (C and D) Immunostaining of synpo in spinal cord after miR-124 intrathecal injections: only the dorsal horn which receive nociceptive information was quantified (white dash area). Measurement of synaptopodin stained area reveals ability of miR-124 to inhibit endogenous Synpo expression (20/3 and 17/3 denotes number of sections/animals for control and miR-124-injected mice, respectively.

I am confident there will be many more positive reports regarding our Transfection Reagents.

Gene Expression-Have it Your Way

From Delivery to Stable Expression
Neuromics has a successful track record of helping our clients delivery siRNA, miRNA, Plasmids and other oligos in vitro and in vivo with our Transfection Kits...But my vision with our cell based assay solutions has always been to provide engineered cells and plasmids modified to study your genes of interest. I am pleased to announce we are working with Smart Cell /B-MoGen Technologies to make this happen. We now can provide:
Gene Transfer and Expression Products Leveraging the Sleeping Beauty Technology:

Advantages of Sleeping Beauty Transposon System:
· Delivery method is time and cost effective compared to lentiviral delivery.
· Increased cargo-capacity when compared to lentiviral delivery.
· Safest insertion profile of all gene transfer methods.
· Commonly integrated as a single copy.
Custom vector design and assembly, including multi-gene (up to 6) vectors.
We are in the process of formulating standard offerings. In the meantime, I am positioned to offer favorable pricing and terms to early adopters of our Sleeping Beauty Solutions.
