AbstractWebsite

Introduction: Compared to synthetic herbicides, natural products with allelochemical properties can inhibit weed germination, aiding agricultural output with less phytotoxic residue in water and soil. Objectives: To identify natural product extracts of three Cassia species; C. javanica, C. roxburghii, and C. fistula and to investigate the possible phytotoxic and allelopathic potential. Methods: Allelopathic activity of three Cassia species extracts was evaluated. To further investigate the active constituents, untergated metabolomics using UPLC-qTOF-MS/MS and ion-identity molecular networking (IIMN) approach was performed to identify and determine the distribution of metabolites in different Cassia species and plant parts. Results: We observed in our study that the plant extracts showed consistent allelopathic activity against seed germination (P < 0.05) and the inhibition of shoot and root development of Chenopodium murale in a dose-dependent manner. Our comprehensive study identified at least 127 compounds comprising flavonoids, coumarins, anthraquinones, phenolic acids, lipids, and fatty acid derivatives. We also report the inhibition of seed germination, shoot growth, and root growth when treated with enriched leaf and flower extracts of C. fistula, and C. javanica, and the leaf extract of C. roxburghii. Conclusion: The present study recommends further evaluation of Cassia extracts as a potential source of allelopathic compounds in agricultural systems. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

BACKGROUND: The lack of effectiveness of acute myeloid leukemia (AML) treatment remains a major challenge and resembles a principal cause of AML-related mortality owing to chemotherapy resistance. SNAI1 has been proved to be a leading factor in drug resistance in many cancer types. However, its relation to chemoresistance in AML is not well understood.

METHODS: In addition to standard lab work, the expression level of SNAI1 was determined in bone marrow samples of 109 adult and pediatric patients with de novo acute myeloid leukemia using RT-qPCR. The relation between SNAI1 and AML drug resistance and immunomodulatory genes was investigated using the STRING tool.

RESULTS: The SNAI1 expression level was upregulated in AML patients in particular samples with promyelocytic leukemia subtype against control cases. In the treatment response, SNAI1 was significantly higher in resistant patients in comparison with the complete remission group. SNAI1 overexpression was associated with high initial blasts and total leukocyte counts, but with HLA class II histocompatibility antigen DR downregulation. STRING analysis showed that multiple drug resistance and immunomodulatory genes of AML induce SNAI upregulation and activation. Kaplan-Meier analysis indicated that there was no relation between SNAI1 expression level and patient survival status.

CONCLUSION: We conclude that the SNAI1 expression level may be a predictor of intrinsic drug resistance incidence in AML patients.

Ahmed, "Bone Marrow-Derived Mesenchymal Stem Cells and -Secretase Inhibitor Treatments Suppress Amyloid-25-35-Induced Cognitive Impairment in Rat Dams and Cortical Degeneration in Offspring.", Stem cells international, vol. 2023, pp. 2690949, 2023. Abstract

Alzheimer's disease (AD) is the most frequent cause of age-related neurodegeneration and ensuing cognitive impairment. Progressive deposition of extracellular amyloid beta (A) aggregates (plaques) and intracellular hyperphosphorylated Tau protein (p-Tau) are the core pathological markers of AD but may precede clinical symptoms by many years, presenting a therapeutic window of opportunity. Females are more frequently afflicted by AD than males, necessitating evaluation of novel treatments for the female population. The current study examined the protective efficacies of intravenous bone marrow-derived mesenchymal stem cells (BM-MSCs) and oral gamma-secretase inhibitor-953 (GSI-953) during pregnancy on cognitive impairment in rat dams and neurodegeneration in offspring induced by intracerebroventricular injection of A25-35 prior to pregnancy. The A25-35 (AD) group exhibited significant ( < 0.001) impairments in the Y-maze and novel object recognition test performance prior to conception. Histological analysis of the offspring cortex revealed substantial dendritic shrinkage and activation of microglial cells, while neurochemical analysis demonstrated significant increases in the proinflammatory cytokine interleukin-1 (IL-1) and tumor necrosis factor- (TNF-). In contrast, BM-MSC or GSI-953 treatment of dams following A25-35 injection significantly ( < 0.001) reduced the number and size of activated microglial cells, markedly increased dendrite length, and reversed proinflammatory cytokine elevations in offspring. Moreover, BM-MSC or GSI-953 treatment reversed the A25-35-induced amyloid precursor protein and p-Tau elevations in the offspring brain; these changes were accompanied by upregulation of the brain-derived neurotrophic factor and downregulation of glycogen synthase kinase-3 in the serum and brain. Treatment with BM-MSCs or GSI-953 also reversed A25-35-induced elevations in different gene expressions in the neonatal cortex. Finally, treatment of dams with BM-MSCs or GSI-953 prevented the A25-35-induced disruption of newborn brain development. Thus, BM-MSC and GSI-953 treatments have broad-spectrum effects against A25-35-induced brain pathology, including the suppression of neural inflammation, restoration of developmental plasticity, and promotion of neurotrophic signaling.
