Dehydroepiandrosterone (DHEA) is a natural hormone with many beneficial properties including an anticancer activity. Unfortunately, DHEA is unstable in the body and exhibits cytotoxicity against healthy cells. In this study, a series of new phosphocholines containing DHEA at sn-1 and/or sn-2 positions were prepared. Succinic acid was used as a linker between the active drug and sn-glycero-3-phosphocholine. All the compounds were evaluated in vitro for their antiproliferative activities against four cell lines: Balb/3T3, HL-60, B16, and LNCaP. The results showed that phosphocholines with DHEA at sn-1 and/or sn-2 positions did not have cytotoxic effects on the normal cell line (Balb/3T3). Mixed-chain phospholipids with DHEA and fatty acid residues showed the highest activity against tumor cell lines. The most active compound, 11c, showed a moderate cytotoxic effect against the HL-60 and B16 cell lines.

Breast cancer (BC) is one of the main causes of cancer-related death in women. The purpose of this study was to evaluate the expression of miR-605-5p in BC and its diagnostic and prognostic value. BC patients and healthy individuals who met the study criteria were included.

Invasive ductal carcinoma (IDC) is a major type of breast cancer. The utilization of inhibitors targeting histone methyltransferases introduces novel therapeutic avenues for the treatment of cancer. Immunohistochemistry, Western blot, and reverse transcription quantitative polymerase chain reaction experiments were applied to assess the levels of EHMT2 in IDC and adjacent tissues.

The Hippo pathway and its transcription co-activator YAP play a critical role in the regulation of cell proliferation, apoptosis and the control of organ size. In the past several years, YAP has been found to be expressed in various human cancers, however, its expression in Nasopharyngeal Carcinoma (NPC) remains unstudied. In this report, we found that YAP was overexpressed in human NPC tissues, and its expression was also significantly higher in five NPC cell lines when compared with the nasopharyngeal epithelial cell line NP69 (P < 0.

New treatment strategies are required to combat the spread of drug-resistant malaria. The synthesis and preclinical evaluation of novel 3-hydroxy-propanamidines (HPAs), with modifications of the phenanthrene and the 4-fluorobenzamidine moieties, has yielded several analogs exhibiting excellent in vitro growth inhibition of drug-sensitive or resistant fresh clinical isolates and culture-adapted strains. No cytotoxicity in the human HepG2 cell line was observed, demonstrating notable parasite selectivity.

Acute myeloid leukemia (AML) with rearrangement of the mixed lineage leukemia gene express MLL-AF9 fusion protein, a transcription factor that impairs differentiation and drives expansion of leukemic cells. We report here that the zinc finger protein GFI1 together with the histone methyltransferase LSD1 occupies the promoter and regulates expression of the lncRNA ELDR in the MLL-r AML cell line THP-1. Forced ELDR overexpression enhanced the growth inhibition of an LSD1i/ATRA combination treatment and reduced the capacity of these cells to generate leukemia in xenografts, leading to a longer leukemia-free survival.
