چکیده

Phospholipase C zeta 1 (PLCζ1), which transcribes a key protein, has an important function in oocyte activation and embryo development because PLCζ1 can trigger a series of intracellular Ca2+ oscillations in mammals. In this study, a novel splice variant in the testis tissues of adult and fetal Chinese Holstein bulls was characterized by reverse transcription-polymerase chain reaction (RT-PCR) and sequencing analysis. The novel splice variant PLCζ1-sv1 was derived from the PLCζ1 complete transcript (PLCζ1-complete) by alternative splicing; the alternative splicing pattern exhibited alternative 5'-splice sites. The full-length transcript, PLCζ1-complete, is the main transcript found in fetal and adult cow testis tissue. Quantitative real-time PCR (qPCR) analysis demonstrated that the expression levels of the PLCζ1-complete transcript were significantly higher than those of the PLCζ1-sv1 splice variant in bovine testis tissues. PLCζ1 protein sequencing analysis showed that the amino acids at positions 453 to 457 were deleted in PLCζ1-sv1, thereby terminating transcription prematurely. In summary, this study provided information to elucidate the structure and function of the bovine PLCζ1 gene.

Identification of a Novel Splice Site Mutation in RUNX2 Gene in a Family with Rare Autosomal Dominant Cleidocranial Dysplasia

Introduction: Pathogenic variants of RUNX2, a gene that encodes an osteoblast-specific transcription factor, have been shown as the cause of CCD, which is a rare hereditary skeletal and dental disorder with dominant mode of inheritance and a broad range of clinical variability. Due to the relative lack of clinical complications resulting in CCD, the medical diagnosis of this disorder is challen...

P-232: Gene Expression Analysis of the Histon Variant H2BFWT in Testis Tissues of Non-Obstructive Azoospermic Patients Referred to Royan Institute

Background: During the later stages of spermatogenesis, spermatid nuclear remodeling and condensation are associated with histone modifications and the sequential displacement of histones by transition proteins and then by protamines. In humans, approximately 15% of the sperm DNA remains packaged by histones in sequence-specific areas. The histone variant H2B, member W, testis-specific (H2BFWT)...

Expression profile of ZFX isoform3/variant 5 in gastric cancer tissues and its association with tumor size

Objective(s):Previous studies demonstrate that changes in pre-mRNA splicing play a significant role in human disease development. Furthermore, many cancer-associated genes are regulated by alternative splicing. There are mounting evidences that splice variants which express predominantly in tumors, have clear diagnostic value and may provide potential drug targets. Located on the X chromosome, ...
