BACKGROUNDApproximately 80% of childhood cancers can now be cured but a side effect treatment results in about one-third the surviving boys being infertile or severely subfertile when they reach reproductive age. Currently, more than 1 5000 men age who are cancer survivors suffer from this serious quality life problem. It is possible to obtain testicular biopsy before preserve spermatogonial stem cells (SSCs) male by cryopreservation, long-term storage SSCs on their subsequent functional...
Insight regarding mechanisms controlling gene expression in the spermatogonial stem cell (SSC) will improve our understanding of processes regulating spermatogenesis and aid treating problems associated with male infertility.

Abstract Identifying triple negative breast cancer (TNBC) patients expected to have poor outcomes provides an opportunity enhance clinical management. We applied Evolutionary Action Score functionally characterize TP53 mutations (EAp53) in 96 TNBC and observed that EAp53 stratification may identify associated with worse outcomes. These findings merit further exploration larger cohorts treated neoadjuvant chemotherapy regimens.
Understanding the initial mechanisms by which epithelial cells transform to an invasive phenotype is critical development of diagnostics that can identify metastatic potential cancers as well therapeutic agents prevent metastases. Changes in cellular response transforming growth factor-beta (TGF-β) cytokine are known promote cell invasion and metastasis part through induction epithelial-mesenchymal transitions (EMTs). In this report, we demonstrate non-metastatic human prostate cancer lines...
Abstract Background Cyclin-dependent kinase 4/6 inhibitors (CDKi) have changed the landscape for treatment of patients with hormone receptor positive, human epidermal growth factor 2-negative (HR+/HER−) metastatic breast cancer (MBC). However, next-line strategies after CDKi progression are not yet optimized. We report here impact clinical and genomic factors on post-CDKi outcomes in a single institution cohort HR+/HER2− MBC. Methods retrospectively reviewed medical records MBC that received...
Breast cancer (BCa) has many well-known risk factors, including age, genetics, lifestyle, and diet; however, the influence of gut microbiome on BCa remains an emerging area investigation. This study explores connection between microbiome, dietary habits, risk. We enrolled newly diagnosed patients age-matched cancer-free controls in a case-control study. Comprehensive patient data was collected, habits assessed through National Cancer Institute Diet History Questionnaire (DHQ). 16S rRNA...
760 Background: Pancreatic adenosquamous carcinoma (PASC) is a rare histopathological type of pancreatic cancer that more aggressive than ductal adenocarcinoma (PDAC). Although PASC has unique tumor biology and poorer prognosis, there are no guidelines for differentially treating patients, its rarity makes it significantly understudied. We used Nanostring GeoMX digital spatial profiling (DSP) to provide targeted proteomic characterization key tumor-promoting proteins in PDAC. Methods: FFPE...
Abstract Background: First-line CDKi and endocrine therapy has improved survival for patients with mHRBC. Upon progression, the optimal treatment strategy mHRBC without a targetable mutation in PIK3CA, AKT, PTEN or ESR1 is unclear. The CAPItello-291 trial showed that targeting PIK3CA pathway after progression-free survival, including identifiable genomic alterations AKT PTEN. Protein expression analysis may identify whether signaling pathways such as PIK3CA/AKT are upregulated proffer...
