Purpose: Although publicly available cancer-related information online and offline could help patients make informed decisions, it also poses challenges due to prevalent misinformation. Patients need proper provider guidance to ensure they use valid and relevant information in decisions. We identify effective communication approaches for providers when (1) discussing patient-identified information and (2) disagreeing with it.

The guidance cue netrin-1 promotes both growth cone attraction and growth cone repulsion. How netrin-1 elicits diverse axonal responses, beyond engaging the netrin receptor DCC and UNC5 family members, remains elusive. Here, we demonstrate that murine netrin-1 induces biphasic axonal responses in cortical neurons: Attraction at lower concentrations and repulsion at higher concentrations using both a microfluidic-based netrin-1 gradient and bath application of netrin-1.

Adeno-associated virus (AAV) inverted terminal repeats (ITRs) induce p53-dependent apoptosis in human embryonic stem cells (hESCs). To interrogate this phenomenon, a synthetic ITR (SynITR), harboring substitutions in putative p53 binding sites was generated and evaluated for vector production and gene delivery. Replication of SynITR flanked transgenic genome was similar compared to wild type (wt) ITR, with a modest increase in vector titers.

Cellular senescence is a phenotypic state that contributes to the progression of age-related disease through secretion of pro-inflammatory factors known as the senescence-associated secretory phenotype (SASP). Understanding the process by which healthy cells become senescent and develop SASP factors is critical for improving the identification of senescent cells and, ultimately, understanding tissue dysfunction. Here, we reveal how the duration of cellular stress modulates the SASP in distinct subpopulations of senescent cells.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.

Association of Prehabilitation in the Precystectomy Pathway in Patients With Bladder Cancer on Postoperative Outcomes.

Clin Genitourin Cancer

December 2024

University of North Carolina School of Medicine, Chapel Hill, NC; University of North Carolina Lineberger Comprehensive Cancer Center, Chapel Hill, NC; Department of Urology, University of North Carolina, Chapel Hill, NC.

Purpose: Prehabilitation in patients with bladder cancer recommended for cystectomy has the potential to improve functional status and outcomes after cystectomy. Prior research has shown that increasing exercise preoperatively can improve strength and quality of life, but research has not yet investigated the impact on length of stay, readmissions, complications and mortality.

Methods: We compared historical controls (2021-2022) for patients with bladder cancer who underwent radical cystectomy at a major academic center to those referred for prehabilitation consultation (2023) on postoperative outcomes, namely hospital length of stay, 30 and 90 day readmission rates, postoperative complications and 90-day mortality.

Understanding the downstream consequences of initial Medicare plan selection is necessary to ensure access to and affordability of health care services, especially for older adults with serious illness. We used 2008-2020 data from the Health and Retirement Study to estimate financial and health burden by initial Medicare plan selection (traditional Medicare without supplemental coverage, traditional Medicare plus supplemental coverage, or Medicare Advantage) and self-reported history of cancer. Initially choosing benefits with greater financial protections (either traditional Medicare plus supplemental coverage or Medicare Advantage) relative to traditional Medicare without supplemental coverage was associated with lower levels of out-of-pocket spending and a lower likelihood of reporting cost-related medication nonadherence and fair or poor health.

Mouse models of Kaposi sarcoma-associated herpesvirus (KSHV).

Virology

December 2024

Lineberger Comprehensive Cancer Center and Department of Microbiology and Immunology, The University of North Carolina at Chapel Hill, USA. Electronic address:

Infection with Kaposi sarcoma-associated herpesvirus (KSHV) is a prerequisite for the development of several human cancers, including Kaposi sarcoma and primary effusion lymphoma. Efficient long-term infection with KSHV and subsequent virally induced cell transformation is limited to humans, resulting in a lack of small animal models for KSHV-driven malignancies. Various attempts to create a mouse model for KSHV include infection of humanized mice, generating transgenic mice that ectopically express viral proteins, and grafting KSHV-infected tumor, primary, or immortalized cells onto immunodeficient mice.

The DNA damage response (DDR) mechanisms that allow cells to tolerate DNA replication stress are critically important for genome stability and cell viability. Using an unbiased genetic screen we identify a role for the RING finger E3 ubiquitin ligase RNF25 in promoting DNA replication stress tolerance. In response to DNA replication stress, RNF25-deficient cells generate aberrantly high levels of single-stranded DNA (ssDNA), accumulate in S-phase and show reduced mitotic entry.

HER2DX in HER2-positive inflammatory breast cancer: correlative insights and comparative analysis with noninflammatory breast cancers.

ESMO Open

January 2025

Department of Medical Oncology, Dana-Farber Cancer Institute, Boston, USA; Breast Oncology Program, Dana-Farber Brigham Cancer Center, Boston, USA; Harvard Medical School, Boston, USA.

Background: The HER2DX assay predicts long-term prognosis and pathologic complete response (pCR) in patients with early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer receiving neoadjuvant systemic therapy but has not been evaluated in inflammatory breast cancer (IBC).

Patients And Methods: HER2DX was analyzed in baseline biopsy tissues from 23 patients with stage III HER2-positive IBC on a phase II trial (NCT01796197) treated with neoadjuvant trastuzumab, pertuzumab, and paclitaxel (THP). To assess the assay's predictive accuracy for pCR in IBC, clinical-pathological features and outcomes from this IBC cohort were compared with 156 patients with stage III HER2-positive non-IBC from four different cohorts.
