Shooting for the STARS: Implementing an Evidence-Based Program to Meet the End of Treatment Needs of Childhood Cancer Survivors and Their Families.

The end of treatment (EOT) is a significant time point along the childhood cancer treatment-survivorship continuum, and is recognized as a time when childhood cancer survivors (CCS) and their families experience significant vulnerability and stress. There is a call by families and healthcare professionals alike for standardized, comprehensive EOT services to successfully navigate through this transition period and better cope with posttreatment medical, physical, and social-emotional issues. A multidisciplinary team of pediatric oncology health care professionals developed and implemented a two-session psychoeducational program to address these EOT needs.

We Are Done! Now What? Exploring End of Treatment Needs of Childhood Cancer Survivors and Their Parents.

Increased childhood cancer survival rates have spurred a new body of research pertaining to the cancer-survivorship continuum. Literature suggests a lack of research and guidelines for care at the end of treatment (EOT). To improve the transition to survivorship and determine any posttreatment challenges, this study explored the experiences of childhood cancer survivors (CCSs), parents/caregivers, and pediatric oncology health care professionals (HCPs) at EOT.

Multiomics in primary and metastatic breast tumors from the AURORA US network finds microenvironment and epigenetic drivers of metastasis.

The AURORA US Metastasis Project was established with the goal to identify molecular features associated with metastasis. We assayed 55 females with metastatic breast cancer (51 primary cancers and 102 metastases) by RNA sequencing, tumor/germline DNA exome and low-pass whole-genome sequencing and global DNA methylation microarrays. Expression subtype changes were observed in ~30% of samples and were coincident with DNA clonality shifts, especially involving HER2.

DNA methylation dynamics and dysregulation delineated by high-throughput profiling in the mouse.

We have developed a mouse DNA methylation array that contains 296,070 probes representing the diversity of mouse DNA methylation biology. We present a mouse methylation atlas as a rich reference resource of 1,239 DNA samples encompassing distinct tissues, strains, ages, sexes, and pathologies. We describe applications for comparative epigenomics, genomic imprinting, epigenetic inhibitors, patient-derived xenograft assessment, backcross tracing, and epigenetic clocks.

Evaluation of whole-genome DNA methylation sequencing library preparation protocols.

Background: With rapidly dropping sequencing cost, the popularity of whole-genome DNA methylation sequencing has been on the rise. Multiple library preparation protocols currently exist. We have performed 22 whole-genome DNA methylation sequencing experiments on snap frozen human samples, and extensively benchmarked common library preparation protocols for whole-genome DNA methylation sequencing, including three traditional bisulfite-based protocols and a new enzyme-based protocol.

Epigenomic Reprogramming toward Mesenchymal-Epithelial Transition in Ovarian-Cancer-Associated Mesenchymal Stem Cells Drives Metastasis.

A role for cancer cell epithelial-to-mesenchymal transition (EMT) in cancer is well established. Here, we show that, in addition to cancer cell EMT, ovarian cancer cell metastasis relies on an epigenomic mesenchymal-to-epithelial transition (MET) in host mesenchymal stem cells (MSCs). These reprogrammed MSCs, termed carcinoma-associated MSCs (CA-MSCs), acquire pro-tumorigenic functions and directly bind cancer cells to serve as a metastatic driver/chaperone.

The end of cancer treatment experience for children, adolescents, and their parents: A systematic review of the literature.

Problem Identification: To date, there is limited study of the end of treatment (EOT) transition experiences and needs of children/adolescents with cancer and their parents.

Literature Search: A systematic search identified primary research focusing on EOT, describing child, adolescent, and parental perceptions, experiences, and needs during this transition period. Of 170 articles identified, 22 met inclusion criteria.

Integrated Epigenome, Exome, and Transcriptome Analyses Reveal Molecular Subtypes and Homeotic Transformation in Uterine Fibroids.

Uterine fibroids are benign myometrial smooth muscle tumors of unknown etiology that, when symptomatic, are the most common indication for hysterectomy in the United States. Unsupervised clustering of results from DNA methylation analyses segregates normal myometrium from fibroids and further segregates the fibroids into subtypes characterized by MED12 mutation or activation of either HMGA2 or HMGA1 expression. Upregulation of HMGA2 expression does not always appear to be dependent on translocation but is associated with hypomethylation in the HMGA2 gene body.

Transcriptional heterogeneity in the lactase gene within cell-type is linked to the epigenome.

Transcriptional variation in histologically- and genetically- identical cells is a widespread phenomenon in tissues, yet the processes conferring this heterogeneity are not well understood. To identify contributing factors, we analyzed epigenetic profiles associated with the in vivo transcriptional gradient of the mouse lactase gene (Lct), which occurs in enterocytes along the proximal-to-distal axis of the small intestine. We found that epigenetic signatures at enhancer and promoter elements aligns with transcriptional variation of Lct in enterocytes.

Co-expression of multiple target proteins in plants from a tobacco mosaic virus vector using a combination of homologous and heterologous subgenomic promoters.

To co-express multiple target proteins, we engineered a single-component chimeric tobacco mosaic virus (TMV)-based vector containing homologous and heterologous capsid protein subgenomic RNA promoters. Delivery of this vector into Nicotiana benthamiana plants via agroinfiltration resulted in co-expression of two reporter genes within a single cell. Furthermore, co-expression of a host-specific antisense RNA or a silencing suppressor protein from this vector augmented the accumulation of green fluorescent protein or a vaccine antigen, hemagglutinin from avian influenza virus A/Vietnam/1194/04.
