Summary of "miR-21 targets jnk and ccr7 to modulate the inflammatory response of grass carp following bacterial infection."

Grass carp septicemia is a systemic inflammatory response that develops following a bacterial infection. The hyperinflammatory state develops could lead to septic shock and lethality. There is increasing evidence that microRNAs are involved in the regulation of the inflammatory response. In the present study, miR-21 was confirmed to be involved in the inflammatory response following infection with Aeromonas hydrophila and LPS stimulation. Both jnk and ccr7 were identified as target gene of miR-21 by overexpression, inhibition, and dual luciferase reporter assays experiments. Meanwhile, miR-21 targets the jnk and ccr7 to modulate downstream pro-inflammatory factors tnf-α, il-1β, il-6, and il-12. Our results provide a theoretical basis for exploring the molecular mechanism of grass carp miR-21 regulating inflammation.

Medical and Biotech [MESH] Definitions

Common name for a number of different species of fish in the family Cyprinidae. This includes, among others, the common carp, crucian carp, grass carp, and silver carp.

Exuberant inflammatory response towards previously undiagnosed or incubating opportunistic pathogens. It is frequently seen in AIDS patients following HAART.

A member of the CXC chemokine family that plays a role in the regulation of the acute inflammatory response. It is secreted by variety of cell types and induces CHEMOTAXIS of NEUTROPHILS and other inflammatory cells.

A systemic inflammatory response to a variety of clinical insults, characterized by two or more of the following conditions: (1) fever >38 degrees C or HYPOTHERMIA <36 degrees C; (2) TACHYCARDIA >90 beat/minute; (3) tachypnea >24 breaths/minute; (4) LEUKOCYTOSIS >12,000 cells/cubic mm or 10% immature forms. While usually related to infection, SIRS can also be associated with noninfectious insults such as TRAUMA; BURNS; or PANCREATITIS. If infection is involved, a patient with SIRS is said to have SEPSIS.

Anthranilic acids with a phenyl group on the nitrogen. Members modulate ION CHANNELS and are used as ANTI-INFLAMMATORY AGENTS.
