AI Article Synopsis
- Aspartame, an artificial sweetener found in over 6000 food products, was studied for its effects on HeLa cervical carcinoma cells.
- The study measured cell viability, DNA damage, and reactive oxygen species (ROS) levels after exposing cells to varying concentrations of aspartame over two time periods.
- Results indicated that higher aspartame concentrations significantly decreased cell viability, increased ROS production, and caused DNA fragmentation, with observable signs of cell death (apoptosis and necrosis).
Article Abstract
Aspartame is used as an artificial sweetener in more than 6000 food varieties. The present study aims to determine the effects of aspartame at various concentrations on the cell viability, morphology, ROS level and DNA of human cervical carcinoma cells over two time periods of exposure. The effects of aspartame on HeLa cell viability were investigated using the sulphorhodamine-B assay (SRB assay) and flow cytometry. Alkaline comet assay was carried out to determine the possible DNA damage induced by aspartame. Mitochondria-derived reactive oxygen species (ROS) were determined using 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA). Fluorescence microscopy was used to determine the presence of apoptotic and necrotic cells following aspartame treatment. Cell viability was significantly altered following a higher concentration of aspartame exposure. Mitochondria-derived ROS increased at higher concentrations of aspartame exposure. Exposure to 10 mM and 20 mM of aspartame induced DNA fragmentation. Apoptotic and necrotic bodies were found in the range of 1-20 mM aspartame exposure. Exposure to high concentrations of aspartame may alter cell viability and morphology, and it may induce ROS generation and DNA damage in cervical carcinoma cells.

Correlates of Cetuximab Efficacy in Recurrent and Metastatic Head and Neck Squamous Cell Carcinoma Previously Treated With Immunotherapy.

Purpose: Immune checkpoint inhibitors (ICIs) are now first-line therapy for most patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), and cetuximab is most often used as subsequent therapy. However, data describing cetuximab efficacy in the post-ICI setting are limited.
Methods: We performed a single-institution retrospective analysis of patients with R/M HNSCC treated with cetuximab, either as monotherapy or in combination with chemotherapy, after receiving an ICI.

Adenosine-to-inosine (A-to-I) RNA editing is a prevalent RNA modification essential for cell survival. The process is catalyzed by the Adenosine Deaminase Acting on RNA (ADAR) enzyme family that converts adenosines in double-stranded RNAs (dsRNAs) into inosines, which are read as guanosines during translation. Deep sequencing has helped to reveal that A-to-I editing occurs across various types of RNAs to affect their functions.

Follicular lymphoma is the most common subtype of indolent lymphoma. Despite multiple trials over the past decade showing improved progression-free survival with new first-line therapeutic strategies -such as anti-CD20 maintenance therapy and new glycoengineered anti-CD20 antibodies- no standardized approach has been widely adopted in routine clinical practice. Several factors may explain this, including the increased incidence of infectious adverse events associated with these therapies, particularly during the COVID-19 pandemic, and the lack of overall survival benefit despite long-term follow-up.

Optimal embryonic development depends upon cell-signaling molecules released by the maternal reproductive tract called embryokines. Identity of specific embryokines that enhance competence of the embryo for sustained survival is largely lacking. The current objective was to evaluate effects of three putative embryokines in cattle on embryonic development to the blastocyst stage.

Bacterial cytokinesis begins with polymerization of the tubulin homologue FtsZ into a ring-like structure at midcell, the Z-ring, which recruits the late cell division proteins that synthesize the division septum. Assembly of FtsZ is carefully regulated and supported by a dozen conserved cell division proteins. Generally, these proteins are not essential, but removing more than one is in many cases lethal.
