Triphala (Trl) is an ayurvedic formulation used for treating disorders of the digestive, respiratory, and nervous systems. Its anticancer properties have also been documented. We studied effects of Trl on tubulin, a target protein for several anticancer drugs, and systematically elucidated a possible antiproliferative mechanism of action of Trl. Trl inhibited proliferation of HeLa (cervical adenocarcinoma), PANC-1 (pancreatic adenocarcinoma), and MDA-MB-231 (triple-negative breast carcinoma) cells in microgram quantities and strongly suppressed the clonogenicity of HeLa cells...

Purpose Malignancy-related hypercalcemia (MRH) is associated with a dismal prognosis. The widespread use of bisphosphonates (BPs), availability of more effective drugs in cancer treatment, and improvement in supportive care might have attenuated its impact. Patients and Methods To assess overall survival (OS) of patients with MRH in a contemporary setting, we conducted a retrospective analysis of 306 patients with solid cancer hospitalized for symptomatic hypercalcemia. A multivariable Cox proportional hazards regression model was performed to evaluate possible prognostic factors associated with MRH...

Given the increased detection rates of ductal carcinoma in situ (DCIS) and the limited overall survival benefit from adjuvant breast irradiation after breast-conserving surgery, there is interest in identifying subsets of patients who have low rates of ipsilateral breast tumor recurrence such that they might safely forgo radiation. The Oncotype DCIS score is a reverse transcription-PCR (RT-PCR)-based assay that was validated to predict which DCIS cases are most likely to recur. Clinically, these results may be used to assist in selecting which patients with DCIS might safely forgo radiation therapy after breast-conserving surgery; however, little is currently published on how this test is being used in practice...

Tumor necrosis factor receptor 1 (TNFR1) is overexpressed in several varieties of carcinoma, including breast cancer. WH701 (Ala-Thr-Ala-Gln-Ser-Ala-Tyr-Gly), which was identified by phage display, can specifically bind to TNFR1. In this study, we labeled WH701 with 18F and investigated its tumor diagnostic value. WH701 was synthesized by standard Fmoc-solid phase synthetic protocols and conjugated by NOTA-NHS. NOTA-WH701 was radiolabeled with 18F using NOTA-AlF chelation reaction. The tumor target properties were evaluated in vitro and in vivo using MCF-7 xenografts and inflammation models...

F-18 NaF PET/CT evaluation has gained importance in recent years. Achievements from F-18 NaF PET/CT are: higher sensitivity of positron imaging, higher target background ratio with higher tracer accumulation in bone hydroxyapatite and higher specificity through CT correlation. These properties have also given directions to new research fields based on imaging microcalcifications, very recently. A limited number of cases have reported the F-18 NaF uptake in macrocalcified soft tissue metastases. Although the presence of microcalcification was not proved; accumulation of F-18 NaF in the metastatic brain lesion with no visible calcification on the CT, in a patient with ductal breast carcinoma has also been reported...

BACKGROUND AND OBJECTIVES: Breast conserving surgery (BCS) can be challenging for large regions of ductal carcinoma in situ (DCIS), resulting in high rates of positive resection margins. Radioactive seed localization (RSL) using multiple radioactive iodine (125I) seeds can be used to bracket extensive DCIS (eDCIS). The goal of this study was to retrospectively compare the use of a single or multiple 125I seeds in RSL to enable BCS in patients with eDCIS. METHODS: All patients with eDCIS (area of ≥3...

BACKGROUND: Endocrine resistance and metastatic dissemination comprise major clinical challenges for breast cancer treatment. The fibroblast growth factor receptor family (FGFR) consists of four tyrosine kinase transmembrane receptors, involved in key biological processes. Genomic alterations in FGFR have been identified in advanced breast cancer and thus, FGFR are an attractive therapeutic target. However, the efficacy of FGFR inhibitors on in vivo tumor growth is still controversial...

Protein ubiquitination and degradation represent druggable vulnerabilities of cancer cells. We used gene expression and functional annotation analyses to identify genes in the ubiquitin pathway which are differentially expressed between normal breast and basal-like tumors. With this approach we identified 16 ubiquitin related genes overexpressed in basal-like breast cancers compared with normal breast. We then explored the association between these genes and outcomes using the KMPlotter online tool. Two genes, the ubiquitin-conjugating enzyme E2T (UBE2T) and the denticleless protein homolog (DTL) were overexpressed and linked with detrimental outcome in basal-like and luminal breast cancer patients...

A competent DNA damage response (DDR) helps prevent cancer, but once cancer has arisen DDR can blunt the efficacy of chemotherapy and radiotherapy which cause lethal DNA breakage in cancer cells. Thus, blocking DDR may improve the efficacy of these modalities. Here we report a new DDR mechanism that interfaces with inflammatory signaling and might be blocked to improve anticancer outcomes. Specifically, we report that the ubiquitin-editing enzyme A20 binds and inhibits the E3 ubiquitin ligase RNF168, which is responsible for regulating histone H2A turnover critical for proper DNA repair...

Background: Heavy metals in tattoo ink can be deposited in axillary lymph nodes, mimicking malignant calcifications. High-density foci in axillary lymph nodes can be the sequelae of a benign or malignant process. Case Report: A 34-year-old female presented with left breast discomfort. Mammography showed suspicious left breast calcifications for which biopsy revealed multicentric ductal carcinoma in situ. Imaging also showed high-density foci in her left axillary lymph nodes suspicious for nodal metastases; however, biopsy of the lymph nodes found the high-density foci to be pigment-laden histiocytes from tattoo ink metallic deposits...
