    Nuclear receptor Ftz-f1 promotes follicle maturation and ovulation partly via bHLH/PAS transcription factor Sim

    Elizabeth M Knapp, Wei Li ... Jianjun Sun
    Genetic analyses illustrate the novel requirement of Ftz-f1 and Sim in adult Drosophila ovaries for regulating follicle cell differentiation and ovulation that is likely conserved in mammals.

    Interferon alpha-inducible protein 6 regulates NRASQ61K-induced melanomagenesis and growth

    Romi Gupta, Matteo Forloni ... Narendra Wajapeyee
    The protein IFI6 regulates DNA replication via the transcription factor E2F2, which is necessary for transformation and growth of melanomas induced by the NRASQ61K mutant oncogene product.

    Nuclear receptor LRH-1/NR5A2 is required and targetable for liver endoplasmic reticulum stress resolution

    Jennifer L Mamrosh, Jae Man Lee ... David D Moore
    LRH-1/NR5A2 responds to ER stress by inducing a novel pathway that is required for stress resolution in mice and can be targeted by LRH-1 agonists.

    Genomic landscape of lymphatic malformations: a case series and response to the PI3Kα inhibitor alpelisib in an N-of-1 clinical trial

    Montaser F Shaheen, Julie Y Tse ... Wadih Arap
    Pathogenic activating mutations in PIK3CA or NRAS were the most common genetic findings in a lymphatic malformation patient cohort and an N-of-1 trial of the PI3Kα inhibitor alpelisib in a patient with a PIK3CA mutation confirmed these findings are actionable.

    miR-146a promotes the initiation and progression of melanoma by activating Notch signaling

    Matteo Forloni, Shaillay Kumar Dogra ... Narendra Wajapeyee
    The microRNA, miR-146a, is regulated by mutant BRAF/NRAS proteins, and promotes the development of melanoma via increasing Notch signaling pathway, suggesting that combining drugs targeting BRAF/NRAS and Notch may provide an effective melanoma treatment.

    Directed differentiation of human iPSCs to functional ovarian granulosa-like cells via transcription factor overexpression

    Merrick D Pierson Smela, Christian C Kramme ... George M Church
    Making human stem cells express certain transcription factors can convert them into cells that are similar to ovarian granulosa cells, and perform several important functions of the ovary.
