A venom derived from one of the planet’s most toxic creatures may someday offer relief for those suffering from diabetes and other hormonal imbalances. The specific venom component, known as consomatin, closely resembles a human hormone called somatostatin, which is key to regulating blood sugar levels. While consomatin serves the cone snail by paralyzing its prey, further exploration into its mechanisms could pave the way for innovative treatments for severe health conditions—provided researchers can demystify its functionality. These findings were highlighted in a recent study published on August 20 in Nature Communications.
Targeted Venoms with Therapeutic Potential
Prior investigations have sought to harness cone snail venoms not only as alternatives to addictive pain medications but also as potential breakthroughs in diabetes therapies. Research conducted in 2016 revealed a structure akin to rapid-acting insulin within the snails that stuns their victims; this knowledge could be vital for developing swifter insulin treatments for humans. In this latest study, consomatin demonstrated remarkable specificity by interacting with particular molecular targets—a characteristic that researchers hope can translate into highly targeted pharmaceuticals.
“The evolutionary processes have honed these toxins to specifically engage essential targets within their prey and disrupt normal biological functions,” quoted Helena Safavi, an associated biochemist at the University of Utah. “Examinations of individual components amid complex venom mixtures can often reveal significant insights related to disease pathways.”

Researchers examined somatostatin’s role in controlling excessive blood sugar levels and compared it with consomatin’s action within their biological systems. While both substances exhibit blood glucose-lowering effects, studies indicated that consomatin proves more chemically robust and enduring than its human counterpart—this stability might be crucial when designing novel therapeutic agents.
The research focused on one of the deadliest species among marine cone snails—the geography cone (Conus geographus), which inhabits Pacific and Indo-Pacific coral reefs where it preys on small fish using its paralytic traits effectively. By studying cell interactions between consomatin and somatostatin functions within laboratory conditions, scientists discovered that while both molecules compete for similar protein interactions, consomatin operates with greater precision by engaging only one target protein rather than multiple ones like somatostatin does.
