The European Corn Borer (ECB), Ostrinia nubilalis (Hübner), is a major corn insect pest. Estimates of damage in the United States due to ECB range between $1-$2 billion per year from yield loss and control costs (Russnogle). A common rule of thumb suggests that one borer per plant can cause a 5% yield loss if the attack occurs during the corn’s critical early development stages (see sidebar). T...

Morphine tolerance is a clinical challenge in pain management. Emerging evidence suggests that microRNA (miRNA) plays a regulatory role in the development of morphine tolerance. miR-219-5p (miR-219) targets calmodulin-dependent protein kinase II γ (CaMKIIγ) to activate central pain sensitization via N-methyl-D-aspartate (NMDA) receptor. Therefore, we hypothesized that miR-219-5p attenuates morp...

Aberrant expression of microRNAs (miRs) has been shown to play a critical role in the pathogenesis and progression of tumors. microRNA-219-5p (miR-219-5p) has been reported to be abnormally expressed in some types of human tumors. However, the mechanism between miR-219-5p and colorectal cancer (CRC) metastasis remains unclear. In the present study, miR-219-5p was found to be downregulated in CR...

Mechanisms underlying delays in resolution programs of inflammation are of interest for many diseases. Here, we addressed delayed resolution of inflammation and identified specific microRNA (miR)-metabolipidomic signatures. Delayed resolution initiated by high-dose challenges decreased miR-219-5p expression along with increased leukotriene B(4) (5-fold) and decreased (~3-fold) specialized pro-r...

Emerging evidence has shown that miRNA-mediated gene expression modulation contributes to chronic pain, but its functional regulatory mechanism remains unknown. Here, we found that complete Freund's adjuvant (CFA)-induced chronic inflammation pain significantly reduced miRNA-219 (miR-219) expression in mice spinal neurons. Furthermore, the expression of spinal CaMKIIγ, an experimentally validat...

The present study aimed to investigate the role of microRNA (miR)-219-5p in spinal cord injury (SCI) and to examine the underlying molecular mechanism. SCI rat and cell models were conducted in the current study, while reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect the level of miR-219-5p in the SCI mice and neurons. Bioinformatics analysis was applied...

Targeting human CD2 with the monoclonal antibody (mAb) CB.219 reduces intestinal inflammation in a colitis model where T cells carry human CD2. Here, we asked whether this mAb has adverse effects on infection control. Mice expressing human CD2 on T cells (huCD2tg) were orally infected with Toxoplasma (T.) gondii and treated with the human CD2-specific mAb CB.219 in a preventive setting. The int...
