Aldehyde dehydrogenase (ALDH) enzymes are involved in the growth and development of several tissues, including cancer cells. It has been reported that targeting the ALDH family, including the ALDH1A subfamily, enhances cancer treatment outcomes. Therefore, we aimed to investigate the cytotoxicity of ALDH1A3-affinic compounds that have been recently discovered by our group, on breast (MCF7 and MDA-MB-231) and prostate (PC-3) cancer cell lines. These compounds were investigated on the selected cell lines as single treatments and in combination with doxorubicin (DOX). Results showed that the combination treatment experiments of the selective ALDH1A3 inhibitors (compounds and ) at variable concentrations with DOX resulted in significant increases in the cytotoxic effect on the MCF7 cell line for compound , and to a lesser extent for compound on the PC-3 cell line, compared to DOX alone. The activity of compounds and as single treatments on all cell lines was found to be non-cytotoxic. Therefore, our findings showed that the investigated compounds have a promising potential to target cancer cells, possibly via an ALDH-related pathway, and sensitize them to DOX treatment.

Mammalian Dicer has been proved to be functional on double-stranded RNAs (dsRNAs) and involved in antiviral immunity or immune regulation. Here, we present a protocol for identifying Dicer as a dsRNA binding and cleaving factor to transfected dsRNA in cell lines, based on small RNA sequencing (RNA-seq) and dsRNA-immunoprecipitation (dsRNA-IP). We detail both experimental processes and analysis on small RNA-seq data.

Objectives: Acute T-cell lymphoblastic leukemia (T-ALL) is a severe hematologic malignancy with limited treatment options and poor long-term survival. This study explores the role of IKZF1 in regulating BCL-2 expression in T-ALL.
Methods: CUT&Tag and CUT&Run assays were employed to assess IKZF1 binding to the BCL-2 promoter.

When performing effect studies to investigate the impact of microplastic (MP) on cell lines, algae, or daphnia, it is advantageous if such experiments can be performed without the use of surfactants. The need for surfactants arises from the fact that finely milled pristine MP particles generally are hydrophobic. Methods for the preparation of larger amounts of hydrophilic and hence artificially aged MP particles and approaches for their characterization are of high importance.

Salmon calcitonin is a small peptide hormone synthesised and released by a specialised gland called ultimobranchial gland in fish. This hormone has been used to treat osteoporosis for over 50 years. The aim of this study was to compare the efficacy of five repeats of salmon calcitonin (5sCT) produced in two different hosts (bacteria and fish cell line).
