Cel-lin-4 is a specific type of RNA found at high levels in young adult hermaphrodites [PMC3282659]. Its levels can be affected by adult age [PMC3282659]. In a study, 1 fmole of two Mimic RNA Spike-in, including cel-lin-4, was added to serum samples to normalize the differences in RNA isolation efficiency [PMC7801652]. To isolate RNA from the serum, 300 μL of serum was homogenized in 900 μL of Trizol LS with the addition of 6 μL of cel-lin-4 [PMC4951333]. Cel-lin-4 was also used as a negative control in experiments as it shows no expression in human tissue [PMC2383925]. The expression levels of miRNA-29c were normalized to that of cel-lin-4 using a specific equation [PMC3696003]. Negative controls including ath-mir159a, cel-miR-2, and cel-miR-124 were used to ensure specificity [PMC1874652]. In another study, recombinant cel-lin-4 was added to samples and no significant differences were found among different groups, thus another control (cel-miR39) was used for normalization purposes [PMC4648542]. The expression levels of miRNAs were calculated using the ΔΔCt method [PMC5641166].

Do you think this miRNA is real?
lin-4 is found on chromosome II in Caenorhabditis elegans [1] and is complementary to sequences in the 3' untranslated region (UTR) of lin-14 mRNA. lin-4 acts to developmentally repress the accumulation of lin-14 protein. This repression is essential for the proper timing of numerous events of Caenorhabditis elegans larval development [2].
