Abstract

Rotifers (phylum Rotifera) are the most common non-arthropod animal. Species in the monogonont rotifer Brachionus are widely distributed in coastal areas and play an important role in aquatic food webs as secondary producers. Brachionus koreanus is currently being developed as a model system for ecotoxicological research. We sequenced the whole transcriptome of B. koreanus using RNA-seq technology. De novo sequence assembly by Trinity integrated with TransDecoder produced 36,918 contigs, including putative alternatively spliced variants. A total of 13,784 genes were identified based on Blast analysis. KEGG pathway analysis detected transcripts annotated as coding for enzymes involved in metabolic pathways, the immune system, translation, and signal transduction. Most identified enzymes and pathways were involved in carbohydrate metabolism, such as the tricarboxylic acid (TCA) cycle and glycolysis. We anticipate that the availability of whole transcriptome data for B. koreanus will provide insights into rotifer biology and physiology and facilitate the development of biomarkers for ecotoxicology studies.

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.
