Targeting pancreatic cancer immune evasion by inhibiting histone deacetylases.

The immune system plays a vital role in maintaining the delicate balance between immune recognition and tumor development. Regardless, it is not uncommon that cancerous cells can intelligently acquire abilities to bypass the antitumor immune responses, thus allowing continuous tumor growth and development. Immune evasion has emerged as a significant factor contributing to the progression and immune resistance of pancreatic cancer. Compared with other cancers, pancreatic cancer has a tumor microenvironment that can resist most treatment modalities, including emerging immunotherapy. Sadly, the u

Inflammatory jaw bone diseases are common in stomatology, including periodontitis, peri-implantitis, medication-related osteonecrosis of the jaw, radiation osteomyelitis of the jaw, age-related osteoporosis, and other specific infections. These diseases may lead to tooth loss and maxillofacial deformities, severely affecting patients' quality of life. Over the years, the reconstruction of jaw bone deficiency caused by inflammatory diseases has emerged as a medical and socioeconomic challenge. Therefore, exploring the pathogenesis of inflammatory diseases associated with jaw bones is crucial fo

Gene expression-based prediction of myeloma cell sensitivity to histone deacetylase inhibitors.

BACKGROUND: Multiple myeloma (MM) is still a fatal plasma cell cancer. Novel compounds are currently clinically tested as a single agent in relapsing patients, but in best cases with partial response of a fraction of patients, emphasising the need to design tools predicting drug efficacy. Histone deacetylase inhibitors (HDACi) are anticancer agents targeting epigenetic regulation of gene expression and are in clinical development in MM. METHODS: To create a score predicting HDACi efficacy, five MM cell lines were treated with trichostatin A (TSA) and gene expression profiles were determined.

Перенос Митохондрии для ремонта миелина.

Обезвоживание является общей характеристикой нейро-воспалительных и дегенеративных заболеваний центральной нервной системы (КНС), таких, как множественный склероз (МС). Часто это связано с нарушениями межклеточной связи, биоэнергетики и метаболического баланса в сочетании с митохондриальной дисфункцией в таких клетках, как олигодендроциты, нейроны, астроциты и микроглиа. Несмотря на то, что нынешние методы лечения MS сосредоточены на иммуномодуляции, они не могут остановить или обратить вспять прогресс демиэлизации. Последние достижения подчеркивают межклеточный митохондриальный обмен в качест

Linking Iron Metabolism, Ferroptosis, and Cancer: New Targets and Prospects for Effective Anticancer Therapeutic Interventions.

New anticancer therapeutic strategies, including targeting of iron dysregulation in affected cancer types and stages, are urgently needed to decrease the associated annual cancer death rate of about 10 million worldwide. Many tumours evade treatment and support metastatic potential by effluxing iron and upregulating antioxidant systems, leading to suppression of lipid peroxidation and ferroptotic cell death. Similarly, many tumours manipulate the tumour microenvironment (TME) by ensuring the continuous supply of iron. This involves phenotypic modulation of immune cells, including macrophages,

The Redox Paradox of Natural Supplements in Cancer: A Narrative Review to Guide Clinical Practice.

Supplements are widely perceived as safe and beneficial; yet in oncology, this assumption is questionable. Clinical trials over the past few decades have often produced disappointing results, raising a critical question: are these agents used correctly, or could they inadvertently cause harm? This review examines supplements frequently used in cancer care-such as oral vitamin C, berberine, N-acetylcysteine, vitamin D, vitamin E, melatonin, polyphenols, alpha-lipoic acid, selenium, and coenzyme Q10-which can act as tumor suppressors or promoters depending on dose, route, and disease stage. We e

Anticancer Activities of Novel Nicotinamide Phosphoribosyltransferase Inhibitors in Hematological Malignancies.

Targeting cancer cells that are highly dependent on the nicotinamide adenine dinucleotide (NAD+) metabolite is a promising therapeutic strategy. Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme catalyzing NAD+ production. Despite the high efficacy of several developed NAMPT inhibitors (i.e., FK866 (APO866)) in preclinical studies, their clinical activity was proven to be limited. Here, we report the synthesis of new NAMPT Inhibitors, JJ08, FEI191 and FEI199, which exhibit a broad anticancer activity in vitro. Results show that these compounds are potent NAMPT inhibito

Don't Cut the Cord: Why Umbilical Cord Blood Still Deserves a Place in Transplantation.

The use of umbilical cord blood (UCB) as a stem cell source in haematopoietic stem cell transplant (HSCT) has greatly declined in recent years. It has largely been replaced by mismatched unrelated and family donors, facilitated by advances in transplant technologies, including post-transplant cyclophosphamide to prevent graft-versus-host disease (GVHD). UCB remains a distinctive source of haematopoietic stem cells (HSCs) with unique immunologic and practical advantages, including for those with malignant and non-malignant diseases. Compared to other cell sources, UCB transplantation (UCBT) off
