AI Article Synopsis

  • RNA FISH is a technique used to locate and quantify specific RNA molecules in fixed cells, providing insight into their expression and activity.
  • The chapter outlines a specific RNA FISH protocol developed to study satellite III RNAs, which are linked to cellular responses to stress, like heat shock.
  • It also details a method for combining RNA FISH with immunofluorescence to simultaneously detect RNA and proteins in cells.

Article Abstract

RNA FISH is a powerful method to detect specific RNAs in fixed cells. It allows both localization and quantification of RNA molecules within individual cells and tissues. Refined RNA FISH methods have also been developed to determine RNA transcription and degradation rates. This chapter describes an RNA FISH protocol that we developed in order to study the expression and localization of satellite III RNAs. This specific class of non-coding RNAs is expressed in response to various cellular stresses including heat shock. This protocol is based on the use of a biotinylated LNA probe subsequently detected by a streptavidin-Alexa Fluor(®) 488 conjugate. A protocol allowing efficient coupling of RNA FISH and protein detection by immunofluorescence is also described in this chapter.

The recombinase polymerase amplification (RPA)-CRISPR-Cas12a-FQ system enables sensitive detection of environmental DNA (eDNA) in rare fish species. Here, we present a protocol for eDNA amplification and Cas12a for target recognition using RPA. We describe steps for identifying a target site, synthesis and purification of CRISPR RNA (crRNA), and RPA isothermal amplification.

The microbiota inhabiting the surface of fish mucosal tissue play important roles in the nutrition, metabolism and immune system of their host. However, most investigations on microbial symbionts have focused on the fish gut, but the microbiota associated with external mucosal tissues (such as the skin and gill) is poorly understood. This study characterised the traits and dynamic of microbial communities associated with the skin, gill and gut of large yellow croaker (Larimichthys crocea) culturing with net enclosures or pens at different sampling times (with seasonal transition).

Electronic address:

As cold-blooded vertebrates, fish are sensitive to environmental changes. The outcome of pathogen infections in fish therefore is highly shaped by hypoxia. The epigenetic regulation of competitive endogenous RNA (ceRNA) bridging non-coding RNAs and mRNAs represents a promising mechanism modulating antibacterial response plus environmental stress.

Acanthopagrus latus (yellowfin seabream) is an economically important fish in the southeast coastal sea of China. Its slower growth rate makes it more prone to diseases in the cultivation period, leading to substantial economic losses. Epidemiological investigations have indicated that Streptococcus agalactiae is one of the most common Gram-positive pathogens, which has garnered increasing attention due to its high contagion and lethality rates in A.

Background: N6-methyladenosine (m6A) is one of the most conserved internal RNA modifications, which has been implicated in many biological processes, such as apoptosis and proliferation. Wilms tumor 1-associating protein (WTAP), as a key component of m6A methylation, is a nuclear protein that has been associated with the regulation of proliferation and apoptosis. Rheumatoid arthritis (RA), a systemic, infiltrating autoimmune disease, is characterized by synovial hyperplasia.
