Doxycycline Restores Gemcitabine Sensitivity in Preclinical Models of Multidrug-Resistant Intrahepatic Cholangiocarcinoma.

Background/objectives: Intrahepatic cholangiocarcinoma (iCCA) is a malignant liver tumor with a rising global incidence and poor prognosis, largely due to late-stage diagnosis and limited effective treatment options. Standard chemotherapy regimens, including cisplatin and gemcitabine, often fail because of the development of multidrug resistance (MDR), leaving patients with few alternative therapies. Doxycycline, a tetracycline antibiotic, has demonstrated antitumor effects across various cancers, influencing cancer cell viability, apoptosis, and stemness.

Emerging Signatures of Hematological Malignancies from Gene Expression and Transcription Factor-Gene Regulations.

Hematological malignancies are a diverse group of cancers developing in the peripheral blood, the bone marrow or the lymphatic system. Due to their heterogeneity, the identification of novel and advanced molecular signatures is essential for enhancing their characterization and facilitate its translation to new pharmaceutical solutions and eventually to clinical applications. In this study, we collected publicly available microarray data for more than five thousand subjects, across thirteen hematological malignancies.

Fibrinogen Structural Changes and Their Potential Role in Endometriosis-Related Thrombosis.

Endometriosis (EM), a chronic inflammatory condition predominantly affecting women of reproductive age, has been linked to an elevated risk of thrombosis, though its underlying molecular mechanisms remain incompletely understood. In this case-control study, involving 71 EM patients and 71 matched controls, we explored the structural and functional changes in fibrinogen and their potential role in thrombosis. Key oxidative stress markers, such as reactive oxygen species (ROS) levels in blood lymphocytes, monocytes, and granulocytes, along with plasma lipid peroxidation markers and total antioxidant capacity, were measured.

In this study, four depsides were isolated from Origanum dictamnus L. and Satureja pilosa Velen. medicinal plants and their structures were assessed by means of one-dimensional (1D)- and two-dimensional (2D)-nuclear magnetic resonance, high resolution mass spectrometry, and electronic circular dichroism analyses.

Multiple Binding Modes of Inhibitors to Human Carbonic Anhydrases: An Update on the Design of Isoform-Specific Modulators of Activity.

Human carbonic anhydrases (hCAs) are widespread zinc enzymes that catalyze the hydration of CO to bicarbonate and a proton. Currently, 15 isoforms have been identified, of which only 12 are catalytically active. Given their involvement in numerous physiological and pathological processes, hCAs are recognized therapeutic targets for the development of inhibitors with biomedical applications.

Effectiveness and safety of intravenous immunoglobulin for peripheral neuropathy in EGPA patients: a retrospective study.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a chronic inflammatory disease belonging to the spectrum of small-vessel vasculitis associated with the presence of anti-neutrophil cytoplasmic antibodies (ANCAs), also characterized by eosinophilic infiltration of target organs. Peripheral neuropathy (PN) affects about 2/3 of the patients as a presenting symptom and typically represents a vasculitic involvement. A few studies have addressed the role of intravenous immunoglobulin (IVIg) for the treatment of PN in EGPA.

A New Bis-Urea Based Cage Receptor for Anions: Synthesis, Solid State Structures and Binding Studies.

The synthesis and characterization of a novel bis-urea-based cage receptor for anions (3S,15S)-3,15,20,25-tetramethyl-1,4,6,12,14,17,20,25-octaazatricyclo[15.5.5.

Interleukin-6 Modulates the Expression and Function of HCN Channels: A Link Between Inflammation and Atrial Electrogenesis.

Inflammatory cytokines, including interleukin 6 (IL6), are associated with ion channel remodeling and enhance the propensity to alterations in cardiac rhythm generation and propagation, in which the hyperpolarization-activated cyclic nucleotide-gated (HCN) channels play a crucial role. Hence, we investigated the consequences of exposure to IL6 on HCN channels in cell models and human atrial biopsies. In murine atrial HL1 cells and in cardiomyocytes derived from human induced pluripotent stem cells (hiPS-CMs), IL6 elicited STAT3 phosphorylation, a receptor-mediated downstream signaling.

4-(Pyrazolyl)benzenesulfonamide Ureas as Carbonic Anhydrases Inhibitors and Hypoxia-Mediated Chemo-Sensitizing Agents in Colorectal Cancer Cells.

Hypoxia in tumors contributes to chemotherapy resistance, worsened by acidosis driven by carbonic anhydrases (CA IX and XII). Targeting these enzymes can mitigate acidosis, thus enhancing tumor sensitivity to cytotoxic drugs. Herein, novel 4-(pyrazolyl)benzenesulfonamide ureas () were developed and evaluated for their inhibitory activity against CA IX and XII.

Plant memory and communication of encounters.

Plants can communicate with each other and other living organisms in a very sophisticated manner. They use biological molecules and even physical cues to establish a molecular dialogue with beneficial organisms as well as with their predators and pathogens. Several studies were recently published that explore how plants communicate with each other about their previous encounters or stressful experiences.

Heterogeneity in adverse events related to atezolizumab-bevacizumab for hepatocellular carcinoma reported in real-world studies.

Background & Aims: Safety data for patients with hepatocellular carcinoma (HCC) treated with atezolizumab-bevacizumab in the real-world setting remain uncertain. Thus, the aim of this study was to evaluate the incidence of adverse events (AEs) in patients with HCC treated with atezolizumab-bevacizumab in the literature.

Methods: In this systematic review and meta-analysis, we searched PubMed for original studies reporting percentages of AEs in patients with HCC receiving atezolizumab-bevacizumab between 2020 to 2023, using the search terms "Atezolizumab/Bevacizumab", "HCC" and "Adverse events".

Immune Checkpoint Inhibitors in the Pre-Transplant Hepatocellular Carcinoma Setting: A Glimpse Beyond the Liver.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and the third leading cause of cancer-related death worldwide. Liver transplantation (LT) is the best therapy for most patients with non-metastatic HCC. In recent years, the management of patients with HCC has considerably changed, thanks to the improvement of molecular biology knowledge and the introduction of immunotherapy.

Dietary Antioxidants and Natural Compounds in Preventing Thrombosis and Cardiovascular Disease.

Reactive oxygen species (ROS) contribute to endothelial dysfunction, platelet activation, and coagulation abnormalities, promoting thrombus formation. Given the growing interest in non-pharmacological approaches to modulate oxidative stress, we examine the potential of various dietary interventions and antioxidant supplementation in reducing oxidative damage and preventing thrombotic events. Key dietary patterns, such as the Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and ketogenic diets, as well as antioxidant-rich supplements like curcumin, selenium, and polyphenols, demonstrate promising effects in improving oxidative stress markers, lipid profiles, and inflammatory responses.

Interleukin 17 producing T cell responses in human chronic trichinellosis-insight from a case study.

Introduction: We studied the cellular immune response in a patient infected since 10 months (along with other 51 people) during a trichinellosis outbreak caused by Trichinella spp.

Methods: A 46 years old female resulted serologically positive for trichinellosis. We isolated peripheral blood mononuclear cells (PBMCs) and incubated them with excretory/secretory antigens (ESA) of Trichinella spiralis (T1) or Trichinella pseudospiralis (T4) to produce antigen specific T cell lines and clones, analysed for the phenotype (T helper or cytotoxic cells), for their T4 or T1 antigens specificity and for their cytokine profile (IFNγ, IL-17A, IL-4) by flow cytometry, thymidine incorporation assay and ELISpot.

Pharmacological treatment landscape of non-metastatic hormone-sensitive prostate cancer: A narrative review on behalf of the meet-URO Group.

The definition of "non-metastatic hormone-sensitive prostate cancer" (nmHSPC) can be applied to patients with prostate cancer (PC) who are androgen-deprivation therapy-naïve and without evidence of metastatic disease. This definition includes heterogeneous situations; however, PC patients at high risk of metastatic spread - and who have not started a hormonal treatment - constitute a unique category with unmet clinical needs. This narrative review critically discusses the advances that characterize the rapidly evolving diagnostic and therapeutic scenario in the nmHSPC setting.
