    Cysteine dioxygenase 1 is a metabolic liability for non-small cell lung cancer

    Yun Pyo Kang et al.
    By increasing intracellular cysteine levels, NRF2 engages a tumor suppressive metabolic pathway mediated by cysteine dioxygenase 1.

    Environmental cystine drives glutamine anaplerosis and sensitizes cancer cells to glutaminase inhibition

    Alexander Muir et al.
    Cell culture models widely used in cancer research do not reflect metabolism in tumors; by altering culture systems to better model tumor metabolism we find that environmental cystine promotes tumor glutamine metabolism.

    The preRC protein ORCA organizes heterochromatin by assembling histone H3 lysine 9 methyltransferases on chromatin

    Sumanprava Giri et al.
    Origin recognition complex-associated (ORCA) is crucial for the stability of the Histone H3 lysine 9 methyltransferase megacomplex, which is essential for heterochromatin organization.

    SIRT2 and lysine fatty acylation regulate the transforming activity of K-Ras4a

    Hui Jing et al.
    A new post-translational regulatory mechanism of K-Ras is identified, which expands the function of reversible protein lysine fatty acylation and offers new possibility to target the K-Ras oncoprotein.

    Methylation of RNA polymerase II non-consensus Lysine residues marks early transcription in mammalian cells

    João D Dias et al.
    Lysine mono- and di-methylation are two novel post-translational modifications of RNA polymerase II, which are enriched at promoters of active genes, precede lysine acetylation and mark early stages of transcription.

    Cystic fibrosis drug ivacaftor stimulates CFTR channels at picomolar concentrations

    László Csanády, Beáta Töröcsik
    Aqueous solubility of cystic fibrosis drug ivacaftor is ~200-fold lower, whereas the potency of its stimulatory effect on the CFTR channel is >100-fold higher, than reported, and is fully reversible.

    Pharmacological inhibition of cystine–glutamate exchange induces endoplasmic reticulum stress and ferroptosis

    Scott J Dixon et al.
    Erastin and sorafenib inhibit system xc- and induce ER stress, suggesting these may be useful tools for probing the functions of system xc- and its role in inducing ER stress and ferroptosis.

    ENaC-mediated sodium influx exacerbates NLRP3-dependent inflammation in cystic fibrosis

    Thomas Scambler et al.
    Dysfunction and overexpression of ENaC-mediated sodium influx exacerbates activation of NLRP3-inflammasome mediated inflammation in cells with CF-associated mutations and is modulated by inhibition of these amiloride-sensitive sodium (Na+) channels.

    Different CFTR modulator combinations downregulate inflammation differently in cystic fibrosis

    Heledd H Jarosz-Griffiths et al.
    CFTR modulators have potent innate anti-inflammatory properties that can be measured in clinic, both ex vivo and in vitro, which can be used to predict treatment efficacy.

    Lysine-14 acetylation of histone H3 in chromatin confers resistance to the deacetylase and demethylase activities of an epigenetic silencing complex

    Mingxuan Wu et al.
    Biochemical approaches reveal that an epigenetic histone deacetylase complex called CoREST is slow to deacetylate histone H3 lysine-14 in nucleosomes, and this inhibits demethylation of histone H3 lysine-4 by the CoREST complex.
