A high-affinity subtype-selective fluorescent probe for estrogen receptor β imaging in living cells.

A high-affinity subtype-selective fluorescent probe for estrogen receptor β imaging in living cells. Chem Commun (Camb). 2018 Apr 03;: Authors: Hu Z, Yang L, Ning W, Tang C, Meng Q, Zheng J, Dong C, Zhou HB Abstract Estrogen receptor β (ERβ) has recently been identified as a pharmaceutical target in hormone replacement therapy for breast cancers. However, the biological function of ERβ in disease progression remains unclear. A highly ERβ-selective fluorescent probe (FPNM) was discovered exhibiting nanomolar affinity for ERβ with an ERβ/ERα selectivity as high as 80, which allowed specific labeling of intracellular ERβ. Moreover, distinct ERβ dynamics in various cellular bio-settings such as prostate cancer (DU-145) or triple-negative breast cancer (MDA-MB-231) cells were directly observed for the first time via FPNM staining.

We report a case of 64-year-old man who presented with the history of lower urinary tract symptoms. The digital rectal examination revealed hard and nodular prostate, and serum prostate-specific antigen level was 23.4 ng/mL. 68Ga-labeled prostate-specific membrane antigen PET/CT revealed prostate-specific membrane antigen–expressing lesions in the prostate, axillary tail of the right breast, and axillary lymph nodes. Histology from prostate revealed prostate carcinoma, whereas fine-needle aspiration from the breast revealed invasive ductal carcinoma of the breast.

We present the case of a 30-year-old woman with triple-negative bilateral breast carcinoma who underwent bilateral mastectomy, chemotherapy, and radiotherapy. She developed a left chest wall and liver recurrence after primary therapy. Her recurrent disease was also triple-negative. In view of the known poor prognosis and very limited therapeutic options, we performed 68Ga-PSMA PET/CT scan to explore the possibility of PSMA-based therapy as a future option after exhausting standard-of-care treatments.

Authors: Cui Z, Li H, Liang F, Mu C, Mu Y, Zhang X, Liu J Abstract WD repeat domain 5 (WDR5) serves an important role in various biological functions through the epigenetic regulation of gene transcription. Aberrant expression of WDR5 has been observed in various types of human cancer, including prostate cancer, breast cancer and leukemia. However, the role of WDR5 expression and its clinical implications in hepatocellular carcinoma (HCC) remain largely unknown. The present study investigated the WDR5 expression pattern in HCC. It was demonstrated that the mRNA and protein levels of WDR5 were upregulated in HCC can...

Conclusions: Smoking increased the overall risk of cancer in primary care practices in the UK. In addition, smoking was predominantly positively and less frequently negatively associated with numerous specific cancers. PMID: 29707117 [PubMed]

Conclusion: Depending on whether female or male mice are used, differences in biodistribution and nonspecific tissue uptake can adversely affect quantitative measures of 18F-FLT uptake. Thus, sex is a potential variable to consider in defining quantitative imaging metrics using 18F-FLT to assess tumor proliferation.

AbstractExosomes are nano-sized vesicles composed of lipids, proteins, and nucleic acids. Their molecular landscape is diverse, and exosomes derived from different cell types have distinct biological activities. Since exosomes are now being utilized as delivery vehicles for exogenous therapeutic cargoes, their intrinsic properties and biological effects must be understood. We performed miRNA profiling and found substantial differences in the miRNA landscape of prostate cancer (PC3) and human embryonic kidney (HEK) 293 exosomes with little correlation in abundance of common miRNAs (R2 = 0.16). Using a systems-...

AbstractIn Australia, one in two men and one in three women will be diagnosed with cancer by the age of 85. Several studies have demonstrated a decline in the number of medical graduates having examined cancer patients during their training. The aim of this study was to evaluate the exposure of medical students to cancer patients during clinical placements. Eighty-eight logbooks (response rate  = 24.75%) containing 9430 patients were analysed. A total of 829 patients (8.79%) had a diagnosis of cancer. Most cancer patients were seen on surgical placements, whilst general practice placements returned the lowest...
