Research progress of nanog gene in fish.

Nanog is a crucial regulatory factor in maintaining the self-renewal and pluripotency of embryonic stem cells. It is involved in various biological processes, such as early embryonic development, cell reprogramming, cell cycle regulation, the proliferation and migration of primordial germ cells. While research on this gene has primarily focused on mammals, there has been a growing interest in studying nanog in fish.

The effects of 1-hexyl-3-methylimidazolium bromide on embryonic development and reproduction in Daphnia magna.

Ionic liquids (ILs) are acknowledged as green chemicals and favorable substitutes for volatile organic solvents, which are currently used. However, previous studies have shown that these compounds had toxicological impacts on aquatic organisms. To investigate the effects of 1-hexyl-3- methylimidazolium bromide ionic liquid ([Cmim]Br) on embryonic development and reproduction in water flea (Daphnia magna), a series of exposure experiments were conducted, including acute toxicity, maternal exposure, and chronic exposure tests.
