Despite the pivotal role of cytotoxic T lymphocytes (CTLs) in anti-tumor immunity, a substantial proportion of CTL-rich hepatocellular carcinoma (HCC) patients experience early relapse or immunotherapy resistance. However, spatial immune variations impacting the heterogeneous clinical outcomes of CTL-rich HCCs remain poorly understood. Here, we compared the single-cell and spatial landscapes of 20 CTL-rich HCCs with distinct prognoses using multiplexed in situ staining and validated the prognostic value of myeloid spatial patterns in a cohort of 386 patients.

The discovery of RET mutations in Multiple Endocrine Neoplasia 2A (MEN2A) in 1993 ignited a revolution in our understanding of this versatile receptor. Since then, RET's influence has expanded to encompass diverse organs, including the pituitary gland. This review explores the multifaceted role of RET in somatotrophs, focusing on two opposing pathways: proliferation versus differentiation and apoptosis.

Background: Despite the current diagnostic techniques and therapeutic methods for colorectal cancer (CRC), patients are often diagnosed at advanced stages of colorectal cancer with poor prognosis and distant metastasis. Recently, numerous investigations have highlighted the crucial role of lncRNAs in cancer development, progression, invasion, and metastasis. This study investigated less well-characterized genes in the colorectal cancer metastasis process using bioinformatics analysis and their confirmation by experimental methods.

Objective: Triple negative breast carcinoma (TNBC) is characterized by the absence of estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2 receptor expression. Carbonic anhydrase IX (CA IX) is a tumor-associated cell surface glycoprotein that is involved in adaptation to hypoxia-induced acidosis and plays a role in cancer progression. The aim of this study was to investigate CA IX expression in TNBC and its relationship with treatment effect.

Tumorigenesis involves a multifaceted and heterogeneous interplay characterized by perturbations in individual immune surveillance. Tumor-infiltrating lymphocytes, as orchestrators of adaptive immune responses, constitute the principal component of tumor immunity. Over the past decade, the functions of tumor-specific T cells have been extensively elucidated, whereas current understanding and research regarding intratumoral B cells remain inadequate and underexplored.
