    Replication Study: Wnt activity defines colon cancer stem cells and is regulated by the microenvironment

    Anthony Essex et al.
    Editors' Summary: This Replication Study has reproduced important parts of the original paper.

    Germinal center B cell development has distinctly regulated stages completed by disengagement from T cell help

    Ting-ting Zhang et al.
    CD40 signaling is necessary to generate the immediate precursors of GC B cells, transition to the BCL6hi follicular state is promoted by a regional and transient diminution of T cell help.

    De-repression of the RAC activator ELMO1 in cancer stem cells drives progression of TGFβ-deficient squamous cell carcinoma from transition zones

    Heather A McCauley et al.
    A new mechanism connects the loss of TGFβ signaling with invasion and metastasis in highly malignant transition zone tumors.

    Regulation of stem/progenitor cell maintenance by BMP5 in prostate homeostasis and cancer initiation

    Mathieu Tremblay et al.
    Gata3 loss in prostate basal stem/progenitor cells upregulates BMP5 which is necessary and sufficient to sustain full self-renewal potential and its inhibition significantly delays both prostate and skin tumor progression.

    A curative combination cancer therapy achieves high fractional cell killing through low cross-resistance and drug additivity

    Adam C Palmer et al.
    Drugs in a curative chemotherapy regimen are independently effective and resisted by different mechanisms, so cancer cells have little chance of surviving all drugs, and this benefit occurs without synergistic interactions.

    Simultaneous enumeration of cancer and immune cell types from bulk tumor gene expression data

    Julien Racle et al.
    A novel method predicts cancer and immune cell types from bulk tumor gene expression data with the ability to consider uncharacterized and possibly highly variable cell types, which is validated in human genome.

    Kin cell lysis is a danger signal that activates antibacterial pathways of Pseudomonas aeruginosa

    Michele LeRoux et al.
    The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.

    Metformin inhibits mitochondrial complex I of cancer cells to reduce tumorigenesis

    William W Wheaton et al.
    The anti-diabetic drug metformin, currently in clinical trials as a potential anti-cancer agent, reduces tumor growth by inhibiting mitochondrial complex I of human cancer cells.
