背景情况:

由Smo调节的刺信号通路在发育和细胞功能中起着至关重要的作用.
之前还没有确定Smo在调节蜜蜂 (Apis mellifera) 嗅觉识别中的特定作用.
嗅觉识别对于蜜蜂寻食物,沟通和生存至关重要.

研究的目的:

为了研究Smo在蜜蜂的嗅觉系统中的作用,Apis mellifera.
确定Smo调制对蜜蜂嗅觉受体表达和嗅觉行为的影响.

主要方法:

扩大和测序的Apis melliferaSmo基因.
对Smo和嗅觉受体 (OR) 基因表达的定量分析,以应对Smo激动剂和对抗剂.
电生理学记录 (电学) 用于评估嗅觉反应.
行为测试以评估气味吸引力和选择率.

主要成果:

在蜜蜂的天线中,Smo的表达很高.
环胺 (Smo抑制剂) 降低了Smo和OR152/OR2的表达,而纯甲胺 (Smo激动剂) 增加了Smo和OR152的表达.
环胺暴露减少了对神经的电天线学反应,并减少了对神经,VUAA1,林纳醇和甲基肝的吸引力.

Leaky Scanning

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

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...
