Small compound 6-O-angeloylplenolin induces mitotic arrest and exhibits therapeutic potentials in multiple myeloma.

BackgroundMultiple myeloma (MM) is a disease of cell cycle dysregulation while cell cycle modulation can be a target for MM therapy. In this study we investigated the effects and mechanisms of action of a sesquiterpene lactone 6-O-angeloylplenolin (6-OAP) on MM cells.Methodology/principal findingsMM cells were exposed to 6-OAP and cell cycle distribution were analyzed. The role for cyclin B1 to play in 6-OAP-caused mitotic arrest was tested by specific siRNA analyses in U266 cells. MM.1S cells co-incubated with interleukin-6 (IL-6), insulin-like growth factor-I (IGF-I), or bone marrow stromal

Использование микробиомных средств для совершенствования методов лечения нейродегенеративных заболеваний: данные о воздействии вдоль оси микробиота-гут-мозгов.

Недавно в качестве полезной модели для понимания возникновения и развития нейродегенеративных заболеваний (НДД) появилась ось микробиота-гут-мозгов (МГБА). Меры воздействия на основе микробиома с использованием биотических добавок (пробиотики, предбиотики, синдиотики, постбиотики) могут модифицировать MGBA и служить подходящими решениями для снижения риска неврологических изменений, связанных с НИЗ, и регулирования симптомов. В настоящем описательном обзоре содержится резюме функционирования МГБС и его взаимодействия с заболеваниями, связанными с началом и развитием НИЗ. Проводится обзор мероп

Application of toll-like receptors (TLRs) and their agonists in cancer vaccines and immunotherapy.

Toll-like receptors (TLRs) are pattern recognition receptors (PRRs) expressed in various immune cell types and perform multiple purposes and duties involved in the induction of innate and adaptive immunity. Their capability to propagate immunity makes them attractive targets for the expansion of numerous immunotherapeutic approaches targeting cancer. These immunotherapeutic strategies include using TLR ligands/agonists as monotherapy or combined therapeutic strategies. Several TLR agonists have demonstrated significant efficacy in advanced clinical trials. In recent years, multiple reports est

The Link Between the Gut Microbiome and Bone Metastasis.

The gut microbiome is essential for regulating host metabolism, defending against pathogens, and shaping the host's immune system. Mounting evidence highlights that disruption in gut microbial communities significantly impacts cancer development and treatment. Moreover, tumor-associated microbiota, along with its metabolites and toxins, may contribute to cancer progression by promoting epithelial-to-mesenchymal transition, angiogenesis, and metastatic spread to distant organs. Bones, in particular, are common sites for metastasis due to a rich supply of growth and neovascularization factors an

Natural and semisynthetic candidate molecules for COVID-19 prophylaxis and treatment.

Coronaviruses (CoVs) represent a family of viruses that have numerous animal hosts, and they cause severe respiratory, as well as systemic and enteric infections, in humans. Currently, there are limited antiviral strategies for treating patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The lack of specific antiviral medicines and SARS-CoV-2 vaccines continues to aggravate the situation. Natural product-based antiviral drugs have been used in the two previous CoV outbreaks: Middle East respiratory syndrome coronavirus (MERS-CoV) and the first SARS-CoV. This re

Natural Compounds with Potential to Modulate Cancer Therapies and Self-Reactive Immune Cells.

Cancer-related deaths are approaching 10 million each year. Survival statistics for some cancers, such as ovarian cancer, have remained unchanged for decades, with women diagnosed at stage III or IV having over 80% chance of a lethal cancer recurrence after standard first-line treatment (reductive surgery and chemotherapy). New treatments and adjunct therapies are needed. In ovarian cancer, as in other cancers, the immune response, particularly cytotoxic (CD8+) T cells are correlated with a decreased risk of recurrence. As well as completely new antigen targets resulting from DNA mutations (ne

Screening the Active Phytochemicals From Eclipta prostrata and Unraveling Their Molecular Insight Into Human Malignancies.

Current drugs against multiple human malignancies are limited, and developing new treatment strategies is improbable within a short time. So, considering the current situation, phytochemicals could be a viable option for developing chemotherapeutic agents for managing numerous types of malignancies. Therefore, we aimed to locate all phytochemicals of Eclipta prostrata and unravel their chemotherapeutic mechanisms and strategies individually. We defined 25 active compounds based on their anticancer activities after filtering through IMPPAT and literature search, and these compounds have chemoth
