Published: November 2020

The dual PI3Kα/ m TOR inhibitors represent a promising molecularly targeted therapy for cancer. Here, we documented the discovery of new 2,4-disubstituted quinazoline analogs as potent dual PI3Kα/sm TOR inhibitors. Our structure based chemistry endeavor yielded six excellent compounds , and with single/double digit nanomolar IC values against both enzymes and acceptable aqueous solubility and stability to oxidative metabolism. One of those analogs, , possessed a sulfonamide substituent, which has not been described for this chemical scaffold before. The short direct synthetic routes, structure-activity relationship, 2D cell culture viability assays against normal fibroblasts and 3 breast cancer cell lines, and 3D culture viability assay against MCF7 cells for this series are described.

Effects of photobiomodulation in mitochondrial quantity, biogenesis and mitophagy-associated genes in breast cancer cells.

Lasers Med Sci

In this article, we aim to evaluate the effects of photobiomodulation on mitochondria quantity, biogenesis, and mitophagy-associated genes in breast cancer (BC) cells. Both models were irradiated with a low-power infrared laser (880 nm, 150 mW) and amber LED (617 nm, 1500 mW), alone or simultaneously. We evaluated the mRNA expression of PINK1 and PGC-1α genes, and the mitochondrial number was assessed based on the ratio of mitochondrial DNA/genomic DNA (mtDNA/gDNA).

Purpose Of Review: The present review describes the available literature on the physiologic mechanisms that modulate hunger, appetite, satiation, and satiety with a particular focus on well-established and emerging factors involved in the classic satiety cascade model.

Recent Finding: Obesity is a significant risk factor for numerous chronic conditions like cancer, cardiovascular diseases, and diabetes. As excess energy intake is considered by some to be the primary driver of weight gain, tremendous collective effort should be directed toward reducing excessive feeding at the individual and population levels.

Liquid biopsy technologies: innovations and future directions in breast cancer biomarker detection.

Globally, breast cancer is the most frequent type of cancer, and its early diagnosis and screening can significantly improve the probability of survival and quality of life of those affected. Liquid biopsy-based targets such as circulating tumor cells, circulating tumor DNA, and exosomes have been instrumental in the early discovery of cancer, and have been found to be effective in stage therapy, recurrence monitoring, and drug selection. Biosensors based on these target related biomarkers convert the tested substances into quantifiable signals such as electrical and optical signals through signal transduction, which has the advantages of high sensitivity, simple operation, and low invasiveness.

Purpose: To evaluate the effects of four-dimensional noise reduction filtering using a similarity algorithm (4D-SF) on the image quality and tumor visibility of low-dose dynamic computed tomography (CT) in evaluating breast cancer.

Materials And Methods: Thirty-four patients with 38 lesions who underwent low-dose dynamic breast CT and were pathologically diagnosed with breast cancer were enrolled. Dynamic CT images were reconstructed using iterative reconstruction alone or in combination with 4D-SF.

Plant cross-fertilization for production of dual-specific antibodies targeting both Ebola virus-like particles and HER2 protein in F plants.

Genes Genomics

January 2025

Department of Medicine, BioSystems Design Lab, College of Medicine, Chung-Ang University, 84 Heukseok-ro, Dongjak-gu, Seoul, 06974, Korea.

Background: This study explores the cross-fertilization of transgenic tobacco plants to produce dual-specific monoclonal antibodies (mAbs) targeting Ebola virus-like particles and HER2 proteins. We generated F plants by hybridizing individual transgenic lines expressing the anti-HER2 breast cancer VHH mAb (HV) and the H-13F6 human anti-Ebola large single chain mAb (EL).

Objective: Hybridizing transgenic plants to express dual-antibodies between different structures VHH and LSCK indicate the potential of transgenic plants as a cost-effective and scalable production system for dual targeting mAbs.
