Thionine Modulates Tau Phosphorylation In An Alzheimer’S Disease Cell Culture Model, Seda Önder, Kevser Bi̇beroğlu, Özden Tacal

Turkish Journal of Biology

Background/aim: Tau protein, which is crucial for sustaining the cytoskeletal network by assisting microtubule construction, contributes significantly to the pathophysiology of Alzheimer’s disease (AD). The hyperphosphorylation of tau causes it to detach from microtubules (MTs), leading to the formation of neurofibrillary tangles (NFTs) in neurons, which ultimately results in cell death. Thionine (TH), a cationic phenothiazine-structured compound, has been the topic of extensive research due to its interesting physicochemical properties. It is a common biological dye, especially useful in histology due to its strong affinity for biological membranes. Furthermore, TH serves as a photosensitizer in phototherapy. It has a phenothiazine …

Butyrylcholinesterase (Bche) Downregulation In Taxane Resistance: Implications For Prostate Cancer, Buse Cevatemre, Arda Işiklar, İpek Bulut, Ezgi̇ Karyemez, Hamzah Syed, Ceyda Açilan

Turkish Journal of Biology

Background/aim: Despite advancements in chemotherapeutic strategies, drug resistance remains a major barrier to effective cancer treatment. While primary prostate cancers (PC) can be treated with surgery and radiotherapy, treatment options for recurrent PC are limited. Upon progression to the castration-resistant (CR) phase, therapies rely on taxanes (chemotherapeutic drugs) like docetaxel (Dtx) and cabazitaxel (Cbz); however, resistance to taxanes is common in CRPC, highlighting the importance of identifying underlying molecular mechanisms or targets in resistant cells.Materials and methods: In transcriptome (RNA sequencing) analyses comparing taxane-resistant PC cells (resistant to both Dtx and Cbz) with parental (nonresistant, sensitive) cells, butyrylcholinesterase (BChE) was …
