Objective: To investigate how mitochondria sense oxygen levels.

Summary: The authors report an oxygen-sensitive regulation of TFAM, an activator of mitochondrial transcription and replication, whose alteration is linked to tumours arising in the von Hippel–Lindau syndrome.

Nat Commun 10(1):5177. doi: 10.1038/s41467-019-13168-4 PMID: 31729379

Objective: To investigate the role of ADSL hydroxylation in controlling cMYC and triple negative breast cancer (TNBC) tumorigenesis.

Summary: ADSL regulates cMYC protein level through adenosine levels and leads to downstream metabolic changes and breast cancer cell proliferation. ADSL is essential for TNBC cell growth and invasiveness and contributes to TNBC breast tumorigenesis and metastasis in vivo.

Prolyl hydroxylation by EglN2 destabilizes FOXO3a by blocking its interaction with the USP9x deubiquitinase.

Zheng X, Zhai B, Koivunen P, Shin S, Lu G, Liu J, Geisen C, Chakraborty A, Moslehi J, Smalley D, Wei X, Chen X, Chen Z, Beres J, Zhang J, Tsao J, Brenner M, Zhang Y, Fan C, DePinho R, Paik J, Gygi S, Kaelin W, Zhang Q (2014) Prolyl hydroxylation by EglN2 destabilizes FOXO3a by blocking its interaction with the USP9x deubiquitinase. Genes Dev 28:1429-1444. doi: 10.1101/gad.242131.114 PMID: 24990963

Summary: Members of the FOXO family are thought to act as tumor suppressor genes. In this work the authors investigated the hydroxylation of FOXO3a by EglN2. This hydroxylation pushes FOXO3a toward a protosomal degradation pathway. Loss of FOXO3a in turn allows the accumulation of Cyclin D1, which has been found to be overexpressed in some breast cancers. Some of the data were generated using immunoblots with anti-transhydroxylated proline (Cat. #AB-T044).
