Transcriptome of Anaplastic Thyroid Cancer Reveals Two Molecular Subtypes with Distinct Tumor Microenvironment and Prognosis.

Thyroid

January 2025

Department of Molecular Medicine and Biopharmaceutical Sciences, Graduate School of Convergence Science and Technology, Seoul National University, Gwanak-gu, Republic of Korea.

Although patients with anaplastic thyroid cancer (ATC) generally have a poor prognosis and there are currently no effective treatment options, survival and response to therapy vary between patients. Genomic and transcriptomic profiles of ATC have been reported; however, a comprehensive study of the tumor microenvironment (TME) of ATC is still lacking. This study aimed to elucidate the TME characteristics associated with ATC and their prognostic implications.

Extracellular vesicles (EVs) are generated in all cells. Systemic administration of allogenic EVs derived from epithelial and mesenchymal cells has been shown to be safe, despite carrying an array of functional molecules, including thousands of proteins. To address whether epithelial cell-derived EVs can be modified to acquire the capacity to induce an immune response, we engineered 293T EVs to harbor the immunomodulatory molecules CD80, OX40L, and PD-L1.

Extracellular vesicles (EVs) are cell derived nanovesicles which are implicated in both physiological and pathological intercellular communication, including the initiation, progression, and metastasis of cancer. The exchange of biomolecules between stromal cells and cancer cells via EVs can provide a window to monitor cancer development in real time for better diagnostic and interventional strategies. In addition, the process of secretion and internalization of EVs by stromal and cancer cells in the tumor microenvironment (TME) can be exploited for delivering therapeutics.

Design of ROS-Triggered Sesquiterpene Lactone SC Prodrugs as TrxR1 Covalent Inhibitors for the Treatment of Non-Small Cell Lung Cancer.

J Med Chem

January 2025

Key Laboratory of Computational Chemistry-Based Natural Antitumor Drug Research & Development, Liaoning Province; Engineering Research Center of Natural Medicine Active Molecule Research & Development, Liaoning Province; Key Laboratory of Natural Bioactive Compounds Discovery & Modification, Shenyang; School of Traditional Chinese Materia Medica, Shenyang Pharmaceutical University, Shenyang, Liaoning 110016, China.

Thioredoxin reductase 1 (TrxR1) is an important therapeutic target for nonsmall cell lung cancer (NSCLC) treatment due to its overexpression in NSCLC cells. In this work, to address the deficiency that sesquiterpene lactone containing α-methylene-γ-lactone moiety was rapidly metabolized by endogenous nucleophiles, series of novel thioether derivatives were designed and synthesized based on a reactive oxygen species (ROS)-triggered prodrug strategy. Among them, prodrug exhibited potent cytotoxicity against NSCLC cells and better release rates in response to ROS.

Université Paris Saclay, AP-HP, Hôpital Bicêtre, Service de Médecine Interne et Immunologie Clinique, CEA, INSERM UMR 1184, Center for Immunology of Viral Infections and Autoimmune Diseases, Le Kremlin Bicêtre France, France.

Purpose Of Review: Long-term immune related adverse events (irAEs) are an increasing reality in cancer patients treated with immune checkpoint inhibitors (ICIs) but remain under-reported. With the number of ICI treated patients increasing, we here aimed to expose the current evidence on their clinical presentations and diagnosis criteria.

Recent Findings: First described in ICI validation trials, long term irAEs were further characterized through retrospective studies, providing clues on their frequency, clinical spectrum, risk factors and impact on patient's quality of life.

Triple-negative breast cancer (TNBC) is a clinically aggressive subtype of breast cancer that remains an unmet medical need. Because TNBC cells do not express the most common markers of breast cancers, there is an active search for novel molecular targets in triple-negative tumors. Additionally, this subtype of breast cancer presents strong immunogenic characteristics which have been encouraging the development of immunotherapeutic approaches against the disease.

Recent studies suggest that lung adenocarcinoma cells are closely associated with the tumorigenesis of large-cell neuroendocrine carcinoma via cellular transformation. However, morphological evidence, along with genetic abnormalities before, during, and after transformation, is quite limited. We present here a case of combined large-cell neuroendocrine carcinoma and adenocarcinoma exhibiting acinar and solid patterns.

Background: Stigma is a pervasive and distressing problem experienced frequently by lung cancer patients, and there is a lack of psychosocial interventions that target the reduction of lung cancer stigma. Mindful self-compassion (MSC) is an empirically supported intervention demonstrated to increase self-compassion and reduce feelings of shame and distress in non-cancer populations. However, there are several anticipated challenges for delivering MSC to lung cancer patients, and modifications may be needed to improve acceptability, appropriateness, and feasibility.

Medullary thyroid cancer (MTC) is a frequently metastatic tumor of the thyroid that develops from the malignant transformation of C-cells. These tumors most commonly have activating mutations within the RET or RAS proto-oncogenes. Germline mutations within RET result in C-cell hyperplasia, and cause the MTC pre-disposition disorder, multiple endocrine neoplasia, type 2A (MEN2A).

Immune-Mediated Liver Injury From Checkpoint Inhibitor: An Evolving Frontier With Emerging Challenges.

Liver Int

February 2025

APHP, Hôpital Paul-Brousse, Centre Hépato-Biliaire, Inserm, Unité 1193, Université Paris-Saclay, FHU Hepatinov, Villejuif, France.

Over the past decade, immune checkpoint inhibitors (ICIs) have transformed the treatment of cancer, though they come with the risk of immune-related adverse (irAEs) events such as hepatotoxicity or Immune-mediated Liver Injury from Checkpoint Inhibitors (ILICI). ILICI is a serious irAE that, when severe, requires cessation of ICI and initiation of immunosuppression. Cytotoxic T Lymphocytes (CTLs) play a central role in ILICI; however, they are just part of the picture as immunotherapy broadly impacts all aspects of the immune microenvironment and can directly and indirectly activate innate and adaptive immune cells.

QuanFormer: A Transformer-Based Precise Peak Detection and Quantification Tool in LC-MS-Based Metabolomics.

Anal Chem

January 2025

State Key Laboratory of Cellular Stress Biology, Institute of Artificial Intelligence, School of Life Sciences, Faculty of Medicine and Life Sciences, National Institute for Data Science in Health and Medicine, XMU-HBN skin biomedical research center, Xiamen University, Xiamen, Fujian 361102, China.

In metabolomic analysis based on liquid chromatography coupled with mass spectrometry, detecting and quantifying intricate objects is a massive job. Current peak picking methods still cause high rates of incorrectly picked peaks to influence the reliability and reproducibility of results. To address these challenges, we developed QuanFormer, a deep learning method based on object detection designed to accurately quantify peak signals.

Introduction: Graft optimization is a necessity in order to develop uterus transplantation from brain-dead donors, as a complement to living donors, as these grafts are rare and the last organs retrieved in multiple organ donation. The aim of this study was to assess the feasibility and interest of hypothermic machine perfusion (HMP) in uterus transplantation using a porcine model; secondary outcomes were the evaluation of the graft's tolerance to a prolonged cold ischaemia time and to find new biomarkers of uterus viability.

Material And Methods: Fifteen uterus allotransplantations were performed in a porcine model, after 18 h of cold ischaemia, divided in three groups: Static cold storage in a HTK solution, HMP (with the VitaSmart (™) machine Bridge to Life Ltd.

The efficient isolation and molecular analysis of circulating tumor cells (CTCs) from whole blood at single-cell level are crucial for understanding tumor metastasis and developing personalized treatments. The viability of isolated cells is the key prerequisite for the downstream molecular analysis, especially for RNA sequencing. This study develops a laser-induced forward transfer -assisted microfiltration system (LIFT-AMFS) for high-viability CTC enrichment and retrieval from whole blood.
