Through natural selection, many animal organs with similar functions have evolved different macroscopic morphologies and microscopic structures. Here, we comparatively investigate the structures, properties and functions of honey bee stings and paper wasp stings. Their elegant structures were systematically observed. To examine their behaviors of penetrating into different materials, we perform...

Lung cancer is the leading cause of cancer death worldwide, microRNAs play critical role in the initiation and development of lung cancer. Here, we used MTT assay, colony formation assay, soft agar growth assay and BrdU incorporation assay to investigate miR-937's role in lung cancer. We found that miR-937 was upregulated in lung cancer tissues and cells. Overexpression of miR-937 in A549 promo...

Peptidylglycine alpha-amidating monooxygenase (PAM), a bifunctional enzyme, catalyzes the COOH-terminal amidation of bioactive peptides. In test tube assays, PAM is phosphorylated by protein kinase C at Ser(937). The roles of phosphorylation and dephosphorylation of Ser(937) in the biosynthetic and endocytic trafficking of integral membrane PAM were examined using an antiserum specific for the ...
