Integrated transcriptome and metabolome analysis revealed hub genes and metabolites associated with subzero temperature tolerance following cold acclimation in rapeseed (Brassica rapa L.).

Rapeseed naturally endures low temperature in late autumn and early winter to develop cold adaptation, named as cold acclimation (CA). The underlying mechanism by which CA induces plant resistance to subzero temperature tolerance is unclear. This study examined the transcriptome and metabolome of strong (Longyou 7) and weak (Longyou 99) cold-tolerant rapeseed varieties treated with treatments CA and sub-zero temperatures at fourth leaf stage.

Novel insights into the unique characterization of N6-methyladenosine RNA modification and regulating cold tolerance in winter Brassica rapa.

N6-methyladenosine (mA) is an mRNA modification considered essential in plants, and is a key player in gene regulation at the transcriptional and translational levels. In present study, we mapped Brassica rapa's whole transcriptome mA profile under low-temperature stress in different cold tolerant varieties to elucidate the mA methylation pattern. The distribution of mA modifications changed significantly under low temperature stress.

A multicenter, randomized, open label, two formulation, crossover bioequivalence trial of doxorubicin hydrochloride liposomal injection in Chinese patients with metastatic breast cancer.

Purpose: The primary objectives of this trial were aimed at exploring the pharmacokinetic profiles and the human bioequivalence of an intravenous liposomal injection of doxorubicin hydrochloride in comparison with a reference formulation in Chinese patients diagnosed with metastatic breast cancer.

Expert consensus on the off-label use in China of drugs for rare hematologic diseases (2024 edition).

Drug package inserts are a crucial foundation for clinical medication practices and serve as the legal basis for guiding rational drug use and ensuring patient safety and efficacy. As rare disease treatments evolve, current package inserts often need to meet the clinical requirements for treating such conditions, frequently resulting in off-label drug use. This consensus is derived from discussions between Guangdong Pharmaceutical Association Hematologic Rare Diseases Group experts.

Mechanism of Apigenin against breast cancer stem cells: network pharmacology and experimental validation.

Apigenin (API), a traditionally sourced flavonoid, is recognized for its anti-neoplastic properties. Despite well-documented effects on tumorigenesis, the detailed therapeutic impact on breast cancer stem cells (BCSCs) and the associated molecular mechanisms are yet to be clarified. The objective of this study is to elucidate the therapeutic effects of API on BCSCs and to uncover its molecular mechanisms through network pharmacology and experimental validation.

Specifically, this study indicated that a water-soluble PBMP fraction 1 (PBMP) was isolated from PBMP.

Dual targeting macrophages and microglia is a therapeutic vulnerability in models of PTEN-deficient glioblastoma.

Tumor-associated macrophages and microglia (TAMs) are critical for tumor progression and therapy resistance in glioblastoma (GBM), a type of incurable brain cancer. We previously identified lysyl oxidase (LOX) and olfactomedin like-3 (OLFML3) as essential macrophage and microglia chemokines, respectively, in GBM. Here, single-cell transcriptomics and multiplex sequential immunofluorescence followed by functional studies demonstrate that macrophages negatively correlate with microglia in the GBM tumor microenvironment.
