[Effect of enhanced silicate minerals weathering on carbon sequestration by plant-soil systems in rice fields].

Successive crop harvest results in soil silicon (Si) loss, which constantly reduces soil available Si. Agricultural measures that can increase the availability of soil Si are in urgent need in agroecosystems. Enhanced weathering of silicate minerals can effectively replenish soil Si, which will promote plant uptake of Si, formation of plant phytolith occluded carbon (PhytOC), and the sequestration of atmospheric CO.

Chidamide and venetoclax synergistically regulate the Wnt/β-catenin pathway by MYCN/DKK3 in B-ALL.

B-cell acute lymphocytic leukemia (B-ALL) is a malignant proliferative B-lymphocyte disease. Although the outcome of B-ALL has greatly improved with combined chemotherapy, immunotherapy, and hematopoietic stem cell transplantation, some patients still experience drug resistance, relapse and a low long-term survival rate, therefore, finding novel approaches to improve the outcome of adult B-ALL patients is critical. Our previous studies revealed that the selective histone deacetylase inhibitor (HDACi) chidamide can inhibit the Wnt/β-catenin signaling pathway by inhibiting MYCN and increasing the expression of DKK3 in B-ALL cells.
