Through the generation of a germline-specific Epas1 knockout mouse line, and through modulation of EPAS1 levels in primary cultures of spermatogonia with the small drug molecule Daprodustat, we have demonstrated that EPAS1 is required for robust SSC function in regenerative conditions (post-transplantation and post-chemotherapy), via the regulation of key cellular processes such as metabolism. These findings shed light on the relationship between hypoxia and male fertility and will potentially facilitate optimization of in vitro culture conditions for infertility treatment pipelines using SSCs, such as those directed at pediatric cancer survivors.]]> Wed 28 Feb 2024 16:12:13 AEDT ]]> Paracingulate sulcus morphology is associated with hallucinations in the human brain https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22665 Wed 11 Apr 2018 12:37:33 AEST ]]> Methylome sequencing in triple-negative breast cancer reveals distinct methylation clusters with prognostic value https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22750 Wed 11 Apr 2018 10:56:04 AEST ]]> A variant at 9p21.3 functionally implicates CDKN2B in paediatric B-cell precursor acute lymphoblastic leukaemia aetiology. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23064 combined=3.32 x 10(-15), OR=1.72) and independent from rs3731217, the previously reported ALL-associated variant in this region. Of correlated SNPs tagged by this locus, only rs662463 is significant in African Americans, suggesting it is a plausible causative variant. Functional analysis shows that rs662463 is a cis-eQTL for CDKN2B, with the risk allele associated with lower expression, and suggests that rs662463 influences BCP-ALL risk by regulating CDKN2B expression through CEBPB signalling. Functional analysis of rs3731217 suggests it is associated with BCP-ALL by acting within a splicing regulatory element determining CDKN2A exon 3 usage (P=0.01). These findings provide new insights into the critical role of the CDKN2 locus in BCP-ALL aetiology.]]> Sat 24 Mar 2018 07:12:28 AEDT ]]>
