A Phase II Trial of Onapristone and Fulvestrant for Patients With ER+ and HER2- Metastatic Breast Cancer.

Background: The SMILE study is a multi-institutional phase II clinical trial to determine the efficacy and safety of an antiprogestin, onapristone, in combination with fulvestrant as second-line therapy for patients with ER+, PgR+/-, HER2- metastatic breast cancer. This study was terminated early and herein, we report patient characteristics, and outcomes.

Methods: Eligibility criteria included disease progression on ≥2 lines of prior therapy, ECOG performance status ≤ 2, measurable disease per RECIST 1.

CLEC12B Regulates Melanocyte Immunity and Homeostasis in the Skin through the Signal Transducer and Activator of Transcription 1/IRF1 Axis.

CLEC12B is a C-type lectin receptor involved in the inhibition of NKs-mediated cytotoxicity. We have previously shown that CLEC12B is predominantly expressed on melanocytes and inhibits melanin production and pigmentation as well as proliferation of melanoma. To date, the role of CLEC12B in skin immunity is unknown.

Mass Spectrometry-Based Workflow for the Identification and Quantification of Alternative and Canonical Proteins in Pancreatic Cancer Cells.

The identification of small proteins and proteins produced from unannotated open reading frames (called alternative proteins or AltProts) has changed our vision of the proteome and has attracted more and more attention from the scientific community. Despite several studies investigating particular AltProts in diseases and demonstrating their importance in such context, we are still missing data on their expression and functions in many pathologies. Among these, pancreatic ductal adenocarcinoma (PDAC) is a particularly relevant case to study alternative proteins.
