چکیده

Mammalian Gene Collection (MGC) verified over 9,000 human full-ORF genes and FLJ Program reported 21,243 cDNAs of which 14,409 were unique ones and 5,416 seemed to be protein-coding. The pity is that epididymis cDNA library was missing in their sequencing target list. Epididymis is a very important male accessory sex organ for sperm maturation and storage. Fully differentiated spermatozoa left from testis acquire their motility and capacity for fertilization via interactions with the epididymal epithelium duct lumen during passage through this convoluted duct. Here, we report that 20,000 clones from a healthy male epididymis cDNA library have been sequenced. The sequencing data provided 8,234 known sequences and 650 unknown cDNA fragments. Hundred and six of 650 unknown cDNA clone inserts were randomly selected for fully sequencing. There were 25 unknown unique sequences and 19 released but unreported sequences came out. By northern blot analysis, four sequences randomly selected from the 19 released sequences with no known function showed positive mRNA signals in epididymis and testis. The signals for three of six from those unknown group showed as epididymis abundant in a region-specific manner but not in the testis and other tissues tested. All the sequencing data will be available on the website www.sdscli.com.

First transcriptome analysis of Iranian scorpion, Mesobuthus eupeus venom gland

Scorpions are generally an important source of bioactive components, including toxins and other small peptides as attractive molecules for new drug development. Mesobuthus eupeus, from medically important and widely distributed Buthidae family, is the most abundant species in Iran. Researchers are interesting on the gland of this scorpion due to the complexity of its venom. Here, we have analyz...

Transcriptome analysis of the freshwater pearl mussel, Hyriopsis cumingii (Lea) using illumina paired-end sequencing to identify genes and markers

The transcriptome of triangle sail mussel Hyriopsis cumingii (Lea) using Illumina paired-end sequencing technology was conducted and analyzed. Equal quantities of total RNA isolated from six tissues, including gonad, hepatopancreas, foot, mantel, gill and adductor muscle, were pooled to construct a cDNA library. A total of 58.09 million clean reads with 98.48 % Q20 bases were generated. Cluster...
