Abstract
This report presents a case of ring chromosome 7 syndrome with bilateral cleft lip and palate. A four-year-old boy presented with bilateral cleft lip and palate, microcephaly, clenched toes, cafe-au-lait spots, a history of epilepsy, and severe intellectual disability. Genetic karyotyping revealed 46 XY r(7) (p22q36). His cheiloplasty and delayed palatoplasty were successful. A review of 22 previous r(7) patients revealed that 22.7% had cleft lip and/or palate. This case demonstrates the importance of a multidisciplinary evaluation for cleft patients, particularly those with syndromic features and global developmental delay.

[PMID: 35538053 PMCID: PMC9091256 DOI: 10.1038/s41420-022-00857-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 12/20/2021] [Accepted: 01/13/2022] [Indexed: 11/09/2022]
Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is a type of leukemia with high malignant behaviors, which seriously threatens the health of people. It has been reported that circFBXW7 is downregulated in lymphoblastic leukemia. Nevertheless, the exact role of circFBXW7 in T-ALL remains elusive. MTT assay was used to assess the cell viability. Cell apoptosis was assessed by flow cytometry. In addition, mRNA expressions were assessed by RT-qPCR, and a western blot was applied to investigate the protein levels. Meanwhile, the correlation among circFBXW7, miR-494-3p, and SOX1 was explored by RNA pull-down and dual-luciferase reporter assays. Furthermore, a xenograft mice model was conducted to verify the function of circFBXW7 in T-ALL in vivo. CircFBXW7 was significantly downregulated in T-ALL, of which overexpression inhibited the cell viability and induced the apoptosis of Jurkat cells. Moreover, miR-494-3p was identified to be a functional downstream effector to be involved in circFBXW7-mediated T-ALL cell proliferation. Besides, SOX1 was a direct target of miR-494-3p, and the impact of miR-494-3p mimics on T-ALL cell growth was inhibited in the presence of SOX1 overexpression. Furthermore, overexpression of circFBXW7 dramatically inhibited T-ALL tumor growth. In summary, circFBXW7 attenuated the tumorigenesis of T-ALL through the mediation of the miR-494-3p/SOX1 axis, which might be novel targets for T-ALL treatment.
