Ibuprofen is an effective treatment to reduce the severe complications and the need for surgical treatment. Several single-nucleotide polymorphisms (SNPs) were related to the ibuprofen metabolism, treatment effects, and the onset of side effects. The effects of SNPs on hsPDA response after ibuprofen treatment are unknown. Therefore, in this study, we recruited hsPDA patients with standard ibuprofen treatment. Those patients had participated in China Neonatal Genomes Project (CNGP, ClinicalTrials.gov Identifier: NCT03931707) with next-generation sequencing data. We reanalyzed the sequencing data and compared the allele frequencies of known ibuprofen-related SNPs between ibuprofen Responder and Non-responder groups. In total, 185 hsPDA patients were recruited with gestational age (GA) ranging from 24 to 40 weeks. No significant differences were detected in the basic information, period of ibuprofen treatment, rate of conservative treatment, complications, and side effects between ibuprofen Responder group and Non-responder group. Totally, 17 hsPDA carried CYP2C9*3 and one with CYP2C9*2 were detected.

Previous studies have reported seasonal fluctuation of BW. However, the responsible environmental factors remain disputable. High-altitude environment provides a great opportunity to test the current hypotheses due to its distinctive climate conditions. We collected BW data of  ~ 9000 Tibetan singletons born at Lhasa (elevation: 3660 m) from 2014 to 2018. Using regression models, we analyzed BW seasonality of highland Tibetans. Multivariate models with meteorological factors as independent variables were employed to examine responsible environmental factors accounting for seasonal variation. We compared BW, low-BW prevalence and sex ratio between highland and lowland populations, and we observed a significant seasonal pattern of BW in Tibetans, with a peak in winter and a trough in summer. Notably, there is a marked sex-biased pattern of BW seasonality (more striking in males than in females). Sunlight exposure in the 3rd trimester and barometric pressure exposure in the 2nd trimester are significantly correlated with BW, and the latter can be explained by seasonal change of oxygen partial pressure. In particular, due to the male-biased BW seasonality, we found a more serious BW reduction and higher prevalence of low-BW in males, and a skewed sex ratio in highlanders. The infant BW of highland Tibetans has a clear pattern of seasonality. The winter BW is larger than the summer BW, due to the longer sunlight exposure during the late-trimester. Male infants are more sensitive to hypoxia than female infants during the 2nd trimester, leading to more BW reduction and higher mortality.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s43657-021-00038-7.</p>","PeriodicalId":74435,"journal":{"name":"Phenomics (Cham, Switzerland)","volume":"2 1","pages":"64-71"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9590487/pdf/43657_2021_Article_38.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9500444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how DDX1 functions in various cancers remains unclear. Here, we explored the potential oncogenic roles of <i>DDX1</i> across 33 tumors with The Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression (GTEx) databases. <i>DDX1</i> is highly expressed in breast cancer (BRCA), cholangiocarcinoma (CHOL), and colon adenocarcinoma (COAD), but it is lowly expressed in renal cancers, including kidney renal clear cell carcinoma (KIRC), kidney chromophobe (KICH), and kidney renal papillary cell carcinoma (KIRP). Low expression of <i>DDX1</i> in KIRC is correlated with a good prognosis of overall survival (OS) and disease-free survival (DFS). Highly expressed <i>DDX1</i> is linked to a poor prognosis of OS for adrenocortical carcinoma (ACC), bladder urothelial carcinoma (BLCA), KICH, and liver hepatocellular carcinoma (LIHC). Also, the residue Ser481 of DDX1 had an enhanced phosphorylation level in BRCA and ovarian cancer (OV) but decreased in KIRC. Immune infiltration analysis exhibited that <i>DDX1</i> expression affected CD8<sup>+</sup> T cells, and it was significantly associated with MSI (microsatellite instability), TMB (tumor mutational burden), and ICT (immune checkpoint blockade therapy) in tumors. In addition, the depletion of <i>DDX1</i> dramatically affected the cell viability of human tumor-derived cell lines. <i>DDX1</i> could affect the DNA repair pathway and the RNA transport/DNA replication processes during tumorigenesis by analyzing the CancerSEA database. Thus, our pan-cancer analysis revealed that <i>DDX1</i> had complicated impacts on different cancers and might act as a prognostic marker for cancers such as renal cancer.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s43657-021-00034-x.</p>","PeriodicalId":74435,"journal":{"name":"Phenomics (Cham, Switzerland)","volume":"2 1","pages":"33-49"},"PeriodicalIF":3.7,"publicationDate":"2022-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9590584/pdf/43657_2021_Article_34.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9145063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
