Abstract

Lipids are a critical source of stored energy in insects, and their metabolism is essential for growth, development, and reproduction. Adequate provisioning of lipids and yolk proteins in the oocytes is essential to ensure reproductive output. Therefore, it is particularly important to understand the molecular mechanisms linking lipid metabolism and reproduction. Lipin proteins are emerging as pivotal modulators of lipid metabolism. They exert a dual function as phosphatidate phosphatase enzymes involved in lipid synthesis and as transcriptional coactivators of genes related to lipid metabolism. However, the functional relationship between lipid metabolism and reproduction remains unclear. In this study, the role of lipin protein in the reproduction of female cabbage beetle Colaphellus bowringi was examined. It was found that Lipin was broadly expressed in the tissues of adult females, with relatively high transcript levels in the head, midgut, fat body, malpighian tubules, and epidermis. RNA interference experiments were conducted using double-stranded RNA against Lipin in C. bowringi females. Lipin silencing blocked ovarian development and strongly suppressed transcription of vitellogenin and vitellogenin receptor genes. In addition, the reduction in Lipin expression led to a rapid increase in lipid storage in the fat body and also promoted the expression of genes related to lipid synthesis and stress tolerance. Overall, these results suggest that a Lipin-mediated lipolytic system is essential for maintaining lipid homeostasis during reproduction in C. bowringi. The findings of this study provide a foundation for future studies on the relationship between lipid metabolism and reproduction in invertebrates.
