AI Article Synopsis

  • Colorectal cancer (CRC) is a major global health issue, characterized by high glycolysis rates in cancer cells, leading to lactic acid production that is exported via monocarboxylate transporters (MCTs).
  • The study analyzed the expression of MCT1, MCT4, CD147, and GLUT1 in primary CRC and its metastases, using immunohistochemistry on human samples.
  • Findings showed overexpression of these proteins in primary CRC and metastases, indicating the importance of MCTs as potential biomarkers and targets for treatment in CRC.

Article Abstract

Background: Colorectal cancer (CRC) is one of the most common malignancies and a leading cause of cancer death worldwide. Most cancer cells display high rates of glycolysis with production of lactic acid, which is then exported to the microenvironment by monocarboxylate transporters (MCTs). The main aim of this study was to evaluate the significance of MCT expression in a comprehensive series of primary CRC cases, lymph node and hepatic metastasis.

Methods: Expressions of MCT1, MCT4, CD147 and GLUT1 were studied in human samples of CRC, lymph node and hepatic metastasis, by immunohistochemistry.

Results: All proteins were overexpressed in primary CRC, lymph node and hepatic metastasis, when compared with non-neoplastic tissue, with exception of MCT1 in lymph node and hepatic metastasis. MCT1 and MCT4 expressions were associated with CD147 and GLUT1 in primary CRC. These markers were associated with clinical pathological features, reflecting the putative role of these metabolism-related proteins in the CRC setting.

Conclusion: These findings provide additional evidence for the pivotal role of MCTs in CRC maintenance and progression, and support the use of MCTs as biomarkers and potential therapeutic targets in primary and metastatic CRC.

Tumor-draining lymph node dendritic cells (DCs) are poor stimulators of tumor antigen-specific CD4 T cells; however, the mechanism behind this defect is unclear. We now show that, in tumor-draining lymph node DCs, a large proportion of major histocompatibility complex class II (MHC-II) molecules retains the class II-associated invariant chain peptide (CLIP) fragment of the invariant chain bound to the MHC-II peptide binding groove due to reduced expression of the peptide editor H2-M and enhanced activity of the CLIP-generating proteinase cathepsin S. The net effect of this is that MHC-II molecules are unable to efficiently bind antigenic peptides.

Primary effusion lymphoma (PEL) is a rare and aggressive B-cell lymphoma typically associated with human herpesvirus 8 (HHV-8) and Epstein-Barr virus infections. It classically presents as a malignant effusion in body cavities, but rarely presents with an extracavitary variant characterized by solid tumors in lymph nodes or extranodal sites such as the gastrointestinal tract, skin, lungs, and nervous system. This case report describes an unusual presentation of primary cutaneous extracavitary PEL in an HIV-positive patient that has only been reported in 8 cases previously.

Background: Immune checkpoint inhibitors (ICIs) show optimal treatment effects on recurrent or metastatic nasopharyngeal carcinoma(R/M NPC). Nonetheless, whether metastatic sites impact ICIs efficacy remains unclear.

Methods: We performed a secondary analysis of R/M NPC patients treated with KL-A167, a programmed cell death-ligand 1(PD-L1) inhibitor, based on a multicenter, single-arm, phase II study from China between 2019 and 2021 years, which represents the first and most comprehensive analysis of the effectiveness of a PD-L1 inhibitor in patients who have been previously treated.

Prognostic relevance of CD163 immune cells in patients with metastatic breast cancer.

Metastatic breast cancer (MBC) is generally considered an incurable disease and even though new treatments are available, the median survival is approximately three years. The introduction of immune therapies for MBC highlights the importance of the immune system in cancer progression and treatment. CD163 anti-inflammatory myeloid cells, including tumor associated macrophages (TAMs), are known to be of relevance in early breast cancer but their role in MBC is not yet established.
