Let's talk about sex! Research suggests natural zebrafish have WZ/ZZ sex chromosomes as evidenced by a single sex-linked region on chromosome 4. This trait is lost in laboratory fish as sex is determined by multiple genes, with influences from the environment. #ZebrafishFunFacts 🧪

Your favorite guessing game has returned to social media! Here's how to play #GuessThatISH:
We present a pic of a #zebrafish embryo that has been stained using an unknown in situ probe by Thisse et al.
You tell us what it looks like! The catch? WRONG ANSWERS ONLY!
Let's play! #ThisseThursday 🧪

The first international workshop that focused on #zebrafish was convened in 1990 in Eugene, Oregon. Sponsored by NIH and NSF, the gathering of ∼40 scientists sought to evaluate the research potential of the tiny fish. Today, nearly 1,800+ zebrafish labs exist worldwide. #ZebrafishFunFacts 🧪

Diamond-Blackfan Anemia (DBA) is a rare human disorder affecting red blood cell production, which often appears due to mutations in ribosomal protein, RPS19. To clarify its role in DBA, researchers made a rps19 knockout #zebrafish, which had impaired haematopoiesis. #KnowYourZDM 🧪
![Figure 1 Zebrafish DBA models. Wild-type embryos show a high density of red blood cells (WT), whereas the blood production is drastically reduced in the rps19 knockdown (KD) and knockout (KO) embryos, as indicated by the absence of hemoglobin stained cells (lower panels). These embryos also display developmental deformities in head and tail regions (arrowheads). The abnormal phenotypes were rescued by injection of rps19 mRNA but not rescued by mRNA with patient type mutations in the knockdown embryos [14].

#KnowYourZDM: Humans and #zebrafish carrying mutations in VEGFC or its receptor (FLT4) have defects in the formation of their lymphatic systems, which are important for draining lymph back into the circulation system. As a result, these individuals display severe #lymphedema. 🧪

On this day seven years ago, I signed back up for social media. It was bittersweet as my previous experiences affected my mental health. But I knew the potential of Zebrafish Rock! Now spread across multiple platforms, we act as a comprehensive resource for the #zebrafish community. Cheers! -KT

Don’t forget the umlaut! Did you know the wild-type strain ‘Tu’ came from a pet shop in the German town of Reutlingen, a nearby city of Tübingen? This area was one of the sites of “The Big Screen” co-led by Christiane Nüsslein-Volhard in the 1990s. #ZebrafishFunFacts @maxplanckcampus.bsky.social 🧪
