AI Article Synopsis

  • Arsenic compounds are effective in treating acute promyelocytic leukemia, leading to complete remission.
  • A new fluorescently labeled arsenic compound was synthesized, suitable for fluorescence techniques in research on arsenic-induced apoptosis.
  • This compound demonstrated successful apoptosis induction and labeling in HL60 leukemia cells, with FITC fluorescence correlating to the amount of arsenic present.

Article Abstract

Arsenic compounds have shown medical usefulness since they proved to be effective in causing complete remission of acute promyelocytic leukemia. In this work we obtained a fluorescently labeled arsenic compound that can be used with current fluorescence techniques for basic and applied research, focused on arsenic-induced apoptosis studies. This compound is an arsanilic acid bearing a covalently linked FITC that was chemically synthesized and characterized by fluorescence, UV-Vis, mass and FTIR spectrometry. In addition, we assessed its apoptotic activity as well as its fluorescent labeling properties in HL60 cell line as a leukemia cell model through flow cytometry. We obtained a compound with a 1:1 FITC:arsenic ratio and a 595 m/z, confirming its structure by FTIR. This compound proved to be useful at inducing apoptosis in the leukemia cell model and labeling this apoptotic cell population, in such a way that the highest FITC fluorescence correlated with the highest arsenic amount.

Heart development involves the complex structural remodelling of a linear heart tube into an asymmetrically looped and ballooned organ. Previous studies have associated regional expansion of extracellular matrix (ECM) space with tissue morphogenesis during development. We have developed morphoHeart, a 3D tissue segmentation and morphometry software with a user-friendly graphical interface (GUI) that delivers the first integrated 3D visualisation and multiparametric analysis of both heart and ECM morphology in live embryos.

Quantitative Analysis of Mitochondria-Associated Endoplasmic Reticulum Membrane (MAM) Stabilization in a Neural Model of Alzheimer's Disease (AD).

A method to quantitate the stabilization of Mitochondria-Associated endoplasmic reticulum Membranes (MAMs) in a 3-dimensional (3D) neural model of Alzheimer's disease (AD) is presented here. To begin, fresh human neuro progenitor ReN cells expressing β-amyloid precursor protein (APP) containing familial Alzheimer's disease (FAD) or naïve ReN cells are grown in thin (1:100) Matrigel-coated tissue culture plates. After the cells reach confluency, these are electroporated with expression plasmids encoding red fluorescence protein (RFP)-conjugated mitochondria-binding sequence of AKAP1(34-63) (Mito-RFP) that detects mitochondria or constitutive MAM stabilizers MAM 1X or MAM 9X that stabilize tight (6 nm ± 1 nm gap width) or loose (24 nm ± 3 nm gap width) MAMs, respectively.

Purpose: Trophoblast cell-surface antigen 2 (Trop2) is overexpressed in various solid tumors and contributes to tumor progression, while its expression remains low in normal tissues. Trop2-targeting antibody-drug conjugate (ADC), sacituzumab govitecan-hziy (Trodelvy), has shown efficacy in targeting this antigen. Leveraging the enhanced specificity of ADCs, we conducted the first immunoPET imaging study of Trop2 expression in gastric cancer (GC) and triple-negative breast cancer (TNBC) models using Zr-labeled Trodelvy ([Zr]Zr-DFO-Trodelvy).

Background: Gastric cancer poses a major diagnostic and therapeutic challenge. Improved visualization of tumor margins and lymph node metastases with tumor-specific fluorescent markers could improve outcomes.

Methods: To establish orthotopic models of gastric cancer, one million cells of the human gastric cancer cell line, MKN45, were suspended in 50 μl of equal parts PBS and Matrigel and injected into the nude mouse stomach with a 29-gauge needle.

Human-derived microRNA 21 regulates indole and L-tryptophan biosynthesis transcripts in the gut commensal .

Unlabelled: In the gut, microRNAs (miRNAs) produced by intestinal epithelial cells are secreted into the lumen and can shape the composition and function of the gut microbiome. Crosstalk between gut microbes and the host plays a key role in irritable bowel syndrome (IBS) and inflammatory bowel diseases, yet little is known about how the miRNA-gut microbiome axis contributes to the pathogenesis of these conditions. Here, we investigate the ability of miR-21, a miRNA that we found decreased in fecal samples from IBS patients, to associate with and regulate gut microbiome function.
