The detection of metastases in Merkel cell carcinoma (MCC) requires additional testing, such as pancytokeratin (panCK) or CK20, with no guarantee of success. Recent findings have identified transcription factor SOX11 and insulinoma-associated protein 1 (INSM1) as sensitive nuclear neuroendocrine markers, but their usefulness in MCC has not been proven.

Although the causes of polycystic ovary syndrome (PCOS) are unclear, researchers know this condition leads to endometrial dysfunction in women who have hormonal imbalances, and insulin resistance. Now, a study led by scientists at the Karolinska Institutet in Sweden has revealed the cellular and genetic differences that distinguish this disorder in the first atlas of the human endometrium during the proliferative phase of the menstrual cycle.

Although CAR T-cell therapies have reached significant clinical success in hematological malignancies, their utility in solid tumors remains limited. One of the main challenges is the scarcity of truly cancer-specific antigens for precise targeting of solid tumors. The use of engineered small, specific antigen-binding domains, such as nanobodies, could be a potential strategy to improve the specificity and efficacy of CAR T cells against solid tumors.

Clear cell renal cell carcinoma (ccRCC) is still a clinical challenge due to its high metastasis rate at diagnosis and therapy resistance. It accounts for about 75%-80% of RCC cases. The magnesium transporter NIPA4 (NIPAL4) may influence tumor progression, but there is lack of knowledge on its prognostic value and role in ccRCC.
