Most school-age children who receive mental health services do so in their public schools, but the scope and quality of those services can vary. This article describes current school mental health efforts in North Carolina, as well as policy initiatives that could shape those practices in the coming years.

Article Synopsis
  • The study investigates the mechanisms behind resistance to HER2-targeted therapies in breast cancer, focusing on the role of tumor-associated fibroblasts (TAFs).
  • TAFs contribute to therapy resistance by producing FGF5, which activates FGFR2 in nearby cancer cells, leading to HER2 activation and a feedback loop that intensifies tumor aggressiveness.
  • Targeting FGFR2 with inhibitors not only blocks HER2 activation but also prompts cell death in resistant cells, suggesting a potential therapeutic strategy to overcome resistance in HER2-positive breast cancer patients.

In breast cancer, estrogen receptor alpha (ERα) positive cancer accounts for approximately 74% of all diagnoses, and in these settings, it is a primary driver of cell proliferation. Treatment of ERα positive breast cancer has long relied on endocrine therapies such as selective estrogen receptor modulators, aromatase inhibitors, and selective estrogen receptor degraders (SERDs). The steroid-based anti-estrogen fulvestrant (5), the only approved SERD, is effective in patients who have not previously been treated with endocrine therapy as well as in patients who have progressed after receiving other endocrine therapies.

TMEM16A, a Ca -activated Cl channel, contributes to tumor growth in breast cancer and head and neck squamous cell carcinoma (HNSCC). Here, we investigated whether TMEM16A influences the response to EGFR/HER family-targeting biological therapies. Inhibition of TMEM16A Cl channel activity in breast cancer cells with HER2 amplification induced a loss of viability.

Tumor types can be defined cytologically by their regions of chromosomal amplification, which often results in the high expression of both mRNA and proteins of certain genes contained within the amplicon. An important strategy for defining therapeutically relevant targets in these situations is to ascertain which genes are amplified at the protein level and, concomitantly, are key drivers for tumor growth or maintenance. Furthermore, so-called passenger genes that are amplified with driver genes and a manifest on the cell surface can be attractive targets for an antibody-drug conjugate approach (ADC).
