    Abstract Objectives: Jie Geng Tang (JGT) is an ancient traditional Chinese herbal decoction that exhibits various pharmacological activities, however, is poorly understood in the sensitivity of lung cancer to chemotherapy. Here, we explored the effect of JGT on sensitizing cisplatin (DDP)-resistant A549 cells (A549/DDP).
    Methods: Cell viability was assessed using cell counting kit-8 assay. Flow cytometry was applied to detected cell apoptosis, mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) levels. Western blotting and qRT-PCR were performed to determine protein and mRNA levels.
    Key findings: The results demonstrated that DDP co-treatment with JGT significantly increased the cytotoxicity of A549/DDP cells and exhibited efficacy in suppressing the migration and proliferation. The rate of apoptosis was increased by co-treatment with DDP and JGT, along with a higher rate of Bax/Bcl-2, and increased loss of MMP. Furthermore, the combination promoted ROS accumulation and increased γ-H2AX levels. Moreover, Nrf2 levels were suppressed in a dose- and time-dependent manner, Nrf2 stability was reduced following treatment with JGT. Notably, the combination induced inhibition of the Nrf2/ARE pathway at the mRNA and protein levels.
    Conclusions: Collectively, these results indicate that co-treatment with JGT and DDP can be considered a combinational approach to treating DDP resistance.

    Abstract By using PacBio HiFi technology, we produced over 700 Gb of long-read sequencing (LRS) raw data; and by using Illumina paired-end whole-genome shotgun (WGS) sequencing technology, we generated more than 70 Gb of short-read sequencing (SRS) data. With LRS data, we assembled one genome and then generate a set of annotation data for an early-matured Geng/japonica glutinous rice mega variety genome, Longgeng 57 (LG57), which carries multiple elite traits including good grain quality and wide adaptability. Together with the SRS data from three parents of LG57, pedigree genome variations were called for three representative types of genes. These data sets can be used for deep variation mining, aid in the discovery of new insights into genome structure, function, and evolution, and help to provide essential support to biological research in general.

    Abstract Hybridization between Xian/indica (XI) and Geng/japonica (GJ) rice combined with utilization of plant ideotypes has greatly contributed to yield improvements in modern GJ rice in China over the past 50 years. To explore the genomic basis of improved yield and disease resistance in GJ rice, we conducted a large-scale genomic landscape analysis of 816 elite GJ cultivars representing multiple eras of germplasm from China. We detected consistently increasing introgressions from three XI subpopulations into GJ cultivars since the 1980s and found that the XI genome introgressions significantly increased the grain number per panicle (GN) and decreased the panicle number per plant. This contributed to the improvement of plant type during modern breeding, changing multi-tiller plants to moderate tiller plants with a large panicle size and increasing the blast resistance. Notably, we found that key gene haplotypes controlling plant architecture, yield components, and pest and disease resistance, including IPA1, SMG1, DEP3, Pib, Pi-d2, and Bph3, were introduced from XI rice by introgression. By GWAS analysis, we detected a GN-related gene Gnd5, which had been consistently introgressed from XI into GJ cultivars since the 1980s. Gnd5 is a GRAS transcription factor gene, and Gnd5 knockout mutants showed a significant reduction in GN. The estimated genetic effects of genes varied among different breeding locations, which explained the distinct introgression levels of XI gene haplotypes, including Gnd5, DEP3, etc., to these GJ breeding pedigrees. These findings reveal the genomic contributions of introgressions from XI to the trait improvements of GJ rice cultivars and provide new insights for future rice genomic breeding.

    Abstract Salinity is a major factor limiting rice productivity, and developing salt-tolerant (ST) varieties is the most efficient approach. Seventy-eight ST introgression lines (ILs), including nine promising lines with improved ST and yield potential (YP), were developed from four BC 2 F 4 populations from inter-subspecific crosses between an elite Geng ( japonica ) recipient and four Xian ( indica ) donors at the Institute of Crop Sciences, Chinese Academy of Agricultural Sciences. Genome-wide characterization of donor introgression identified 35 ST QTLs, 25 of which harbor 38 cloned ST genes as the most likely QTL candidates. Thirty-four are Xian-Geng differentiated ones with the donor ( Xian ) alleles associated with ST, suggesting differentiated responses to salt stress were one of the major phenotypic differences between the two subspecies. At least eight ST QTLs and many others affecting yield traits were identified under salt/non-stress conditions. Our results indicated that the Xian gene pool contains rich ‘hidden’ genetic variation for developing superior Geng varieties with improved ST and YP, which could be efficiently exploited by selective introgression. The developed ST ILs and their genetic information on the donor alleles for ST and yield traits would provide a useful platform for developing superior ST and high-yield Geng varieties through breeding by design in the future.

    Abstract Ethnopharmacological relevance: Tiao Geng (TG) decoction is a Chinese herbal medicine extract that has been utilized for the treatment of menopausal symptoms for a history of over 30 years. In our previous study, we suggest that TG decoction possibly exerts an anti-apoptotic effect on hypothalamic neurons of ovariectomized rats via the ASK1/MKK7/JNK pathway. Tributyltin chloride (TBTC) causes oxidative damage and induces apoptosis of primary hypothalamic neurons in rats.
    Aim of the study: The present work aimed to explore the inhibition of TG decoction on TBTC-induced GT1-7 cell apoptosis and its possible molecular mechanism.
    Materials and methods: The GT1-7 cell line was exposed to TG decoction at diverse doses (31.25, 62.5, 125 μg/mL) for 24 h and later with TBTC (1 mg/L) for 1 h, with 17β-E
    Results: Application of TG decoction mitigated the GT1-7 cell apoptosis and injury caused by TBTC; besides, it inhibited the activation of the ASK1/MKK7/JNK pathway. Moreover, Bcl-2/Bax ratio became higher, and the MKK7, ASK1, Casp3 and c-Jun levels were inhibited. Besides, TG decoction combined with SP600125 (the JNK inhibitor) more significantly inhibited GT1-7 cell apoptosis caused by TBTC.
    Conclusion: As discovered from the experiment in this study, TG decoction has a neuroprotective effect, which is achieved through inhibiting the ASK1/MKK7/JNK signal transduction pathway to reduce GT1-7 cell apoptosis.

    Abstract Jie-Geng-Tang (JGT), a traditional formula, is employed in the treatment of sore throat and cough and comprises Platycodonis Radix and Glycyrrhizae Radix et Rhizoma in the ratio 1 : 2. Our previous study demonstrated that JGT protected mice from S. aureus-induced acute lung injury (ALI). Five constituents of JGT showed antibacterial activities against S. aureus in vitro. However, the potential effective constituents of JGT in vivo were still unclear. In this study, the chemical constituents of JGT were identified by liquid chromatography with quadrupole time-of-flight spectrometry (LC-Q-TOF-MS). A total of 96 constituents were identified or assumed, including seven organic acids, 45 flavonoids, 36 triterpene saponins, and eight compounds of other types. The structures of 31 of the constituents were confirmed by comparing them with corresponding authentic standards. Moreover, 15 prototypes and 49 metabolites were deduced in the serums of mice, 24 prototypes and 47 metabolites were deduced in the lungs of mice after the oral administration of JGT. Three types of constituents, namely organic acids, flavonoids, and triterpene saponins, could be absorbed into the blood. Moreover, flavonoids and triterpene saponins were more likely distributed in the lung than in the blood. To the best of our knowledge, this is the first report on the systematic metabolites profile of JGT in vivo. The results reported were beneficial to the elucidation of the effective material basis of JGT.

Then, CCK8 assay was conducted to evaluate cell viability, while flow cytometric analysis was conducted to examine the apoptosis level. Related pathways and differentially expressed proteins were identified by tandem mass tag (TMT)-based quantitative phosphoproteomics. qRT-PCR was carried out to examine mRNA levels of Bax and B-cell lymphoma-2 (Bcl-2). Western blotting was performed to detect the levels of Bax, Bcl-2, c-Jun, c-Jun N-terminal kinase (JNK), Caspase-3 (Casp3), Mitogen-activated protein kinase kinase 7 (MKK7), and apoptosis signal-regulating kinase 1 (ASK1) .Finally, cells were pretreated with SP600125, an inhibitor of JNK, later the expression of JNK and Casp3 was measured.Application of TG decoction mitigated the GT1-7 cell apoptosis and injury caused by TBTC; besides, it inhibited the activation of the ASK1/MKK7/JNK pathway.

    Abstract Ethnopharmacological relevance: TG-decoction (Tiao Geng decoction) is the extract of a Chinese herb mixture that has been used for treating menopausal symptoms for over 30 years. We have previously reported anti-aging and anti-oxidative effects of the TG-decoction on hypothalamic neurons in ovariectomized (OVX) rats.
    Aim of the study: The present study further investigates the effects of TG-decoction on the prevention of aging-related ultrastructural changes in menopausal hypothalamic neurons and the likely molecular mechanism.
    Materials and methods: A total of 120 four-month-old female SPF Sprague Dawley rats were divided into six groups. Five groups were ovariectomized (OVX) and one group served as a sham control. Three OVX groups received TG-decoction at three different doses. The remaining two OVX groups served as positive and negative controls by receiving estradiol valerate and saline solution. The sham group received saline. After one month, aging-related ultrastructural alterations in hypothalamic neurons were evaluated using transmission electron microscopy. Nissl staining was used to assess the pathomorphological changes of the hypothalamic neurons. Cell apoptosis was evaluated by TUNEL. Expression of Bcl-2 family genes was studied using qRT-PCR. Expression of the apoptosis-related proteins ASK1, MKK7, JNK, c-Jun, Bax, Casp3 and Bcl-2 was studied using western blotting.
    Results: Ovariectomy of female rats led to visible damage and aging-like alterations in the mitochondria and endoplasmic reticulum as well as large deposits of lipofuscin in hypothalamic tissue. TG-decoction treatment prevented this visible damage and lipofuscin deposition, increased the number of nerve cells and normally-shaped Nissl bodies, and reduced the number of TUNEL-positive cells. Expression of Bcl-2 gene was increased, while Bax gene reduced. Expression of the proteins ASK1, MKK7, JNK, c-Jun, Bax and Casp3 was reduced, while that of Bcl-2 was increased.
    Conclusion: TG-decoction reduces aging-related ultrastructural changes in hypothalamic neurons, likely by suppressing ASK1/MKK7/JNK-mediated apoptosis in neuronal mitochondria or nuclei.
