A partial cDNA for 6-phosphogluconate dehydrogenase (PGD, EC 1.1.1.44) was isolated from a porcine liver cDNA library using a rat PGD cDNA. The identity of the PGD cDNA was confirmed by DNA sequencing and comparison of the amino acid sequence with the corresponding ovine sequence. The PGD cDNA was assigned to 6q2.5-2.7 by in situ hybridization.

Polyadenylation of the 3' end of mRNAs is an important mechanism for regulating their stability and translation. We developed a nucleotide-resolution, transcriptome-wide, single-molecule SM-PAT-Seq method to accurately measure the polyA tail lengths of individual transcripts using long-read sequencing. The method generates cDNA using a double stranded splint adaptor targeting the far 3' end of the polyA tail for first strand synthesis along with random hexamers for second strand synthesis.

The aim of this study was to evaluate whether long noncoding RNA accumulation play a role in the pathophysiology of fragile X-associated premature ovarian insufficiency (FXPOI). The study population consisted of 22 consecutive fragile X mental retardation 1 (FMR1) premutation carriers (CGGn 55-199 repeats) undergoing in vitro fertilization and pre-implantation genetic diagnosis (IVF-PGD) treatment. The control group consists of 11 patients, with <55 CGG repeats, undergoing IVF-ICSI for male factor infertility, matched by age, treated in the same period.

Fragile X syndrome (FXS), the most common inherited intellectual disability syndrome, is caused by expansion and hypermethylation of the CGG repeat in the 5' UTR of the FMR1 gene. This expanded repeat, also known as the rare fragile site FRAXA, causes X chromosome fragility in cultured cells from patients but only when induced by perturbing pyrimidine synthesis. We performed preimplantation genetic diagnosis (PGD) on 595 blastomeres biopsied from 442 cleavage stage embryos at risk for FXS using short tandem repeat (STR) markers.

Objective: Chromosomal abnormalities and poor quality are correlated with DNA damage in the pre-implantation stage in humans. This study aimed to explore the altered expression of DNA damage signalling pathways - including apoptosis, cell cycle and DNA repair pathways - in poor-quality pre-implantation human embryos with complex aneuploidy.
Study Design: Surplus Day 4 embryos from candidates undergoing pre-implantation genetic screening were pooled into two groups.

Mutations of Desert hedgehog (DHH) have been associated to 46,XY pure gonadal dysgenesis (PGD) and to mixed gonadal dysgenesis (MGD); however, there have been no functional studies of mutations described in DHH. To determine if mutations p.L162P and Δ1086delG yield functional impairment, we performed in vitro and in silico analysis of both DHH mutants.
