The mechanosensor Filamin A/Cheerio promotes tumourigenesis via specific interactions with components of the cell cortex.

Cancer development has been linked to aberrant sensing and interpretation of mechanical cues and force-generating properties. Here, we show that upregulation of the actin crosslinking protein Cheerio (Cher), the fly ortholog of Filamin A (FLNA), and the conformation of its mechanosensitive region (MSR) are instrumental to the malignancy of polarity-deficient, Ras-driven tumours in Drosophila epithelia. We demonstrate that impaired growth and cytoskeletal contractility of tumours devoid of cher can be rescued by stimulating myosin activity.

Clinical Features and Treatment Outcomes of Warm Autoimmune Hemolytic Anemia: A Retrospective Analysis of 60 Turkish Patients.

We aimed to analyze 10-year experience of WAIHA patients at a single referral center in Turkey. Clinical data, survival outcome of sixty patients who were diagnosed with WAIHA were retrospectively analyzed. All the patients were direct antiglobulin test (DAT) positive.

Interplay among Drosophila transcription factors Ets21c, Fos and Ftz-F1 drives JNK-mediated tumor malignancy.

Cancer initiation and maintenance of the transformed cell state depend on altered cellular signaling and aberrant activities of transcription factors (TFs) that drive pathological gene expression in response to cooperating genetic lesions. Deciphering the roles of interacting TFs is therefore central to understanding carcinogenesis and for designing cancer therapies. Here, we use an unbiased genomic approach to define a TF network that triggers an abnormal gene expression program promoting malignancy of clonal tumors, generated in Drosophila imaginal disc epithelium by gain of oncogenic Ras (Ras(V12)) and loss of the tumor suppressor Scribble (scrib(1)).
