The purpose of this study was to directly compare mutation profiles in multiple single circulating tumor cells (CTC) and cell-free DNA (cfDNA) isolated from the same blood samples taken patients with metastatic breast cancer (MBC). We aimed determine whether cfDNA would reflect heterogeneity observed 40 CTCs.

Abstract BACKGROUND Activating mutations in the estrogen receptor 1 (ESR1) gene are acquired on treatment and can drive resistance to endocrine therapy. Because of spatial temporal limitations needle core biopsies, our goal was develop a highly sensitive, less invasive method detecting activating ESR1 via circulating cell-free DNA (cfDNA) tumor cells as “liquid biopsy.” METHODS We developed targeted 23-amplicon next-generation sequencing (NGS) panel for detection hot-spot ESR1,...

Reversible protein phosphorylation regulated by kinases and phosphatases controls many cellular processes. Although essential functions for the malaria parasite kinome have been reported, roles of most (PPs) during Plasmodium development are unknown. We report a functional analysis berghei phosphatome, which exhibits high conservation with P. falciparum phosphatome comprises 30 predicted PPs differential distinct expression patterns various stages life cycle. Gene disruption reveals that...

PURPOSE Here, we report the sensitivity of a personalized, tumor-informed circulating tumor DNA (ctDNA) assay (Signatera) for detection molecular relapse during long-term follow-up patients with breast cancer. METHODS A total 156 primary cancer were monitored clinically up to 12 years after surgery and adjuvant chemotherapy. Semiannual blood samples prospectively collected, analyzed retrospectively detect residual disease by ultradeep sequencing using ctDNA assays, developed from whole-exome...

Abstract Introduction The stromal microenvironment has a profound influence on tumour cell behaviour. In tumours, the extracellular matrix (ECM) composition differs from normal tissue and allows novel interactions to function. ECM protein tenascin-C (TNC) is frequently up-regulated in breast cancer we have previously identified two isoforms – one containing exon 16 (TNC-16) exons 14 plus (TNC-14/16). Methods present study analysed functional significance of this altered TNC isoform profile...

Cell-cycle progression and cell division in eukaryotes are governed part by the cyclin family their regulation of cyclin-dependent kinases (CDKs). Cyclins very well characterised model systems such as yeast human cells, but surprisingly little is known about number role Plasmodium, unicellular protozoan parasite that causes malaria. Malaria proliferation differs from many eukaryotes. During its life cycle it undergoes two types mitosis: endomitosis asexual stages an extremely rapid mitotic...

Traditional deep learning methods are suboptimal in classifying ambiguity features, which often arise noisy and hard to predict categories, especially, distinguish semantic scoring. Semantic scoring, depending on logic implement evaluation, inevitably contains fuzzy description misses some concepts, for example, the ambiguous relationship between normal probably always presents unclear boundaries (normal-more likely normal-probably normal). Thus, human error is common when annotating images....
