Open AccessSeasonal variation of gut Cyanophyta contents and liver GST expression of mud carp (Cirrhina molitorella) and Nile tilapia (Oreochromis niloticus) in the tropical **angang Reservoir (Huizhou, China)
Liver glutathione S-transferase (GST) plays a major role in the detoxification of microcystins (MCs) via conjugation to glutathione (GSH). We evaluated the relationship between seasonal variation in fish gut c...

Platelets promote tumour metastasis via interaction between TLR4 and tumour cell-released high-mobility group box1 protein
Increasing evidence suggests that TLR4 expression by tumour cells promotes tumour progression, but it is unclear whether TLR4 is involved in metastasis. Here we show that TLR4 deficiency significantly diminishes ...
