چکیده

Crustacean hyperglycemic hormone (CHH) is the most abundant and best studied member of the CHH/MIH/GIH neuropeptide hormone family. CHH plays a major role in controlling glucose levels in the hemolymph, and it also has significance in regulating molting, reproduction, and osmoregulation. In contrast, molt-inhibiting hormone (MIH) is responsible for maintaining animals in an intermolt stage. In this study, Liv-MIH-1 cDNA, which encodes a mature neuropeptide from the eyestalk of white shrimp, Litopenaeus vannamei, was expressed in methylotrophic yeast (Pichia pastoris KM71) under the control of an alcohol oxidase promoter. Recombinant Liv-MIH-1 was

P-198: Utilization of Pichia Pastoris Secretion System for Expression of Equine Follicle Stimulating Hormone

Background: Equine follicle stimulating hormone (eFSH) is a pituitary heterodimeric glycoprotein consists of noncovalently linked of generic alpha subunit and a hormone specific beta subunit. The molecular weights of the subunits are similar and about 16 KD. In general, FSH plays a key role in controlling vertebrate gonadal functions. In female mammals, ovarian maturation and follicular growth ...

P-191: Cloning and Expression of Recombinant Ovine FSH Hormone in Pichia Pastoris

Background: Follicle stimulating hormone is a heterodimeric protein composed of two subunits, α and ß, which are linked noncovalently. The hypophysial gonadotropin FSH plays an important role in the regulation of oocyte maturation, and a key component for growth of ovulator follicles in ewes. Materials and Methods: This study seeks to clone and express the ovine follicle stimulating hormone sub...

Expression and applications of recombinant crustacean hyperglycemic hormone from eyestalks of white shrimp (Litopenaeus vannamei) against bacterial infection.

Crustacean hyperglycemic hormone (CHH) has many functions to regulate carbohydrate metabolism, ecdysis and reproduction including ion transport in crustaceans. The cDNA encoding CHH peptides containing 369 bp open reading frame encoding 122 amino acids was cloned from eyestalk of white shrimp (Litopenaeus vannamei) and was produced by a bacterial expression system. The biological activity of re...

Cloning and Characterization of cbhII Gene fromTrichoderma parceramosum and Its Expressionin Pichia pastoris

The genomic and cDNA clones encoding cellobiohydrolase II (CBHII) have been isolated and sequenced from a native Iranian isolate of Trichoderma parceramosum, a high cellulolytic enzymes producer isolate. This represents the first report of cbhII gene from this organism. Comparison of genomic and cDNA sequences indicates this gene contains three short introns and also an open reading frame codin...
