In the present study, we investigated the role of recombinant human phospholipase D2 (rhPLD2) on proliferation and apoptosis in human leukemia HL-60 cells which induced by camptothecin. Our research demonstrated that various concentrations of rhPLD2 inhibit the growth of HL-60 cells in a dose-dependent manner, and rhPLD2 plus camptothecin can produce a synergistic effect on growth inhibition of HL-60 cells in vitro. So, we conclude that rhPLD2 alone cannot induce apoptosis in HL-60 cells, but it can potentiate the apoptosis of HL-60 cells induced by camptothecin. Similarly, we show that both rhPLD2 and standard PLD were able to enhance camptothecin-induced apoptosis of HL-60 cells.

Anacardic acid (AA) is a phenolic lipid extracted from cashew nutshell liquid that has antitumor activity. Given the high hydrophobicity of this compound and aiming to create efficient vehicle for its administration in aqueous systems, the objective of the present work was to develop a microcapsule (MCAA) by spray dryer technique, based on the polysaccharide sodium hyaluronate (SH), containing AA as its core, encapsulated from nanoemulsion. The Encapsulation Efficiency of MCAA presented a value equal to 95.

Article Synopsis
- The study investigates the effects of Bisphenol A (BPA) and Tetrabromobisphenol A (TBBPA) on the dynamics of biological membranes, focusing on how these persistent organic pollutants impact myeloid cell lines.
- It was found that TBBPA specifically disrupts the plasma membrane's biophysical homeostasis, increasing mobility and decreasing order, while BPA showed no significant effects.
- The findings highlight TBBPA's potential to impair immune function, emphasizing the environmental toxicity concerns associated with persistent organic pollutants.

Oncostatin M (OSM) plays a crucial role in diverse inflammatory reactions. Although the food bioactive compound naringenin (NAR) exerts various useful effects, including antitussive, anti-inflammatory, hepatoprotective, renoprotective, antiarthritic, antitumor, antioxidant, neuroprotective, antidepressant, antinociceptive, antiatherosclerotic, and antidiabetic effects, the modulatory mechanism of NAR on OSM expression in neutrophils has not been specifically reported. In the current work, we studied whether NAR modulates OSM release in neutrophil-like differentiated (d)HL-60 cells.

Article Synopsis
- A-ring modifications in 1α,25-dihydroxyvitamin D enhance its binding to the vitamin D receptor (VDR) and increase its stability in cells by resisting metabolism, leading to longer-lasting effects.
- Various modified A-ring precursors synthesized from d-glucose showed specific biological activities with minimal calcemic side effects, including MART-10's potent antitumor effects in cancer models and AH-1's superior bone-forming properties in osteoporosis models compared to natural vitamin D.
- Ongoing research includes developing a library of fluorinated vitamin D analogs with potential anti-inflammatory effects and therapeutic applications for conditions like psoriasis, alongside the creation of the VDR-silent analog KK-052, which selectively inhibits SREBP/SC
