通过RNA干扰 (RNAi) 来抑制hdh-BMP7的表达.
测量后RNAi. 的生长参数 (外长度,宽度,重量).
实时定量逆转录PCR (qRT-PCR) 用于基因表达分析.

主要成果:

hdh-BMP7基因编码了416种氨基酸,包括一个信号,TGF-β和成熟的TGF-β.
hdh-BMP7 mRNA在H.discus hannai组织中得到广泛表达,其中有四种单核酸多态 (SNP) 与生长特征相关.
通过RNAi抑制hdh-BMP7导致下游基因 (hdh-BMPR I,hdh-BMPR II,hdh-smad1,hdh-MHC) 的表达减少,并且显著减少了外的长度,宽度和总重量.

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Hedgehog Signaling Pathway

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
