Example 15

Fibrogenesis has been understood as an excessive wound healing process against disorder of a cell or tissue. Thus, suppression of disorder of a cell or tissue along with fibrogenesis has been considered to be effective for treatment of various fibrosis. Then, in order to investigate whether NEK6 knockdown would exhibit effect on hepatic disorder, measurement of hepatic disorder markers in CCl4 models was performed.

On day 13 after induction of pathology, blood draw was performed from tail vein using a plane capillary blood-sampling tube, and subjected to standing for 30 minutes or more. The post-standing blood was centrifuged to obtain serum. Serum glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase (GOT) were measured using Transaminase CII-test Wako (Wako Pure Chemical Industries, Ltd.). Measurement method followed the instruction of the reagent.

FIG. 17a has shown measurement results of serum GPT, and FIG. 17b has shown measurement results of serum GOT. Elevation of serum GPT and GOT found in CCl4 models was suppressed by administering NEK6 siRNAs. Consequently, it was shown that NEK6 knockdown suppresses hepatic disorder.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
