RESUMO

BACKGROUND: Overconsumption of sodium has been identified as a key driving factor for diet-related cardiovascular diseases (CVDs). China, being a country bearing a hefty burden of CVD, has a large population with diverse cultural traditions and ethnic beliefs, which complicates the patterns of dietary sodium intake, necessitating a systematic investigation into the profile of the high sodium intake (HSI)-related burden of CVD within its subregions. This study aims to estimate the evolving patterns of HSI-induced CVD burden across China from 1990 to 2019. METHODS: The methodology used in the Global Burden of Disease Study was followed to assess deaths and disability-adjusted life years (DALYs) by age, sex, region, and socio-demographic index (SDI). The estimated annual percentage change (EAPC) was calculated to quantify the secular changes in the age-standardized mortality rate (ASMR) and age-standardized DALY rate (ASDR). RESULTS: In 2019, 0.79 million deaths and 1.93 million DALYs of CVD were attributed to HSI, an increase of 53.91% and 39.39% since 1990, respectively. Nevertheless, a downward trend in ASMR (EAPC: -1.45, 95% CI: -1.55, -1.35) and ASDR (EAPC: -1.61, 95% CI: -1.68, -1.53) was detected over time. ASMR and ASDR were higher for males, individuals aged ≥60 years, and regions with low-middle SDI. A markedly negative association between the EAPC in both ASMR and ASDR and the SDI was found in 2019 (ρ = -0.659, p < 0.001 and ρ = -0.558, p < 0.001, respectively). CONCLUSIONS: The HSI-induced CVD burden is gender-, age-, and socioeconomic-dependent. Integrated and targeted strategies for CVD prevention are anticipated in the future throughout China.

RESUMO

BACKGROUND: Studies have shown that phenylethanoid glycosides (PhGs) have multiple pharmacological effects such as anti-inflammatory, hepatoprotective or neuroprotective functions, whereas their anti-tumor effects are rarely studied. Tubuloside B (Tub B) is a PhG isolated from Cistanche deserticola, a traditional Chinese medicine. To date, there is a lack of comprehensive research regarding the biological activity of Tub B. PURPOSE: The subject of the current study was to investigate the anti-hepatocellular carcinoma (HCC) cell activity and the underlying mechanism of Tub B. METHODS: We evaluated the in vitro anti-migratory effect of Tub B by scratch and transwell assays. RNA-seq was employed to identify the differential genes by Tub B. Besides, the functional mechanism of Tub B was investigated by distinct molecular biology techniques including immunofluorescent staining, quantitative PCR, as well as western blot analysis. Subsequently, we utilized Hep3B cells for in vivo metastasis assays through spleen injection and evaluated the anti-migratory effect of Tub B in hepatocellular carcinoma (HCC). RESULTS: Tub B exhibited in vitro and in vivo inhibition of HCC cell migration. Tub B decreased the expression of transcriptional target genes downstream of the Hippo pathway, including CTGF, CYR61, and N-cadherin as determined by RNA-seq. Furthermore, mechanistic studies confirmed that Tub B increased phosphorylation of YAP at S127, which contributes to YAP cytoplasmic localization. Additionally, overexpression of YAP abrogated Tub B-induced inhibition of HCC migration and the mRNA levels of CTGF, CYR61, and N-cadherin. CONCLUSIONS: Taken together, these results illustrated that Tub B demonstrated great potential in inhibiting migration of HCC, and a portion of its impact can be attributed to the modulation of the Hippo-YAP pathway.

RESUMO

Purpose: Adagrasib is a selective and reversible inhibitor of KRAS G12C, which significantly delays the progression of solid tumors. However, the absorption, distribution, metabolism, and excretion of adagrasib in vivo are unclear. This study explores the absorption and distribution of adagrasib in vivo. Methods: An ultra-high performance liquid chromatography-tandem quadrupole mass spectrometry (UPLC-MS/MS) method was established for the determination of adagrasib in the rat plasma and tissue. Sprague-Dawley rats were intravenous administrated (5 mg/kg) and oral administrated (30 mg/kg) with adagrasib, and the plasma concentration of adagrasib was determined. After single oral administration of adagrasib (30 mg/kg), the heart, liver, spleen, lung, kidney, intestine, and pancreas were excised. The organs were homogenized with saline solution, and the concentration of adagrasib in tissues was determined. Results: The intra- and inter-day accuracy were from 84.90% to 113.47%, and the precision was within ±15%. The matrix effect and recovery were within ±15%. The maximum plasma concentration (Cmax) of adagrasib was 677.45 ± 58.72 ng/mL. The elimination half-life time (t1/2) was 3.50 ± 0.21 h after oral administration and 2.08 ± 0.54 h after intravenous administration. The oral bioavailability was 50.72%. The highest concentrations of adagrasib in liver was 5047.80 ± 676.48 ng/g at 2 h after administration, and it was still detectable at 24 hours after administration. Conclusion: Adagrasib was slowly absorbed and cleared rapidly, and it was also widely distributed in vivo. This study provides a potential reference for adagrasib in clinical studies.

RESUMO

Lung cancer is an extremely aggressive and highly prevalent disease worldwide, and it is one of the leading causes of cancer death. Deciphering intrinsic genetic mechanism, finding new targets, and overcoming drug resistance are the key to lung cancer treatment. High-throughput CRISPR screening has been extensively used to obtain the genes related to cancers including lung cancer. This review describes CRISPR/Cas9 or CRISPR/dCas9-based technologies for high-throughput screening. We summarize the applications of CRISPR screening technology in exploring the mechanism of lung cancer development in vivo or in vitro, overcoming drug resistance, improving the effect of immunotherapy, and discovering new therapeutic targets. This review highlights the potential of CRISPR screening in combination with tumor barcoding and high-throughput sequencing (Tuba-seq) to precisely quantify the impact of alterations in many tumor suppressor genes on lung cancer.

RESUMO

Spiraea thunbergii (S. thunbergia) is a very common ornamental shrub in the garden, with important horticultural and economic value. In this study, we assembled the complete chloroplast (cp) genome of S. thunbergia into a typical quadripartite structure. The genome size and GC content of the S. thunbergia cp genome are 155,922 bp and 36.76%, respectively. It contains 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogenetic tree supported that S. thunbergii is closely related to Spiraea mongolica in the Rosaceae family. The study will provide significant genomic resource for elucidating the phylogenetic relationship of Spiraea.

RESUMO

Liver cancer is a life-threatening disease, and its incidence is increasing globally. The most common form of liver cancer is hepatocellular carcinoma (HCC). Approximately half of patients with HCC, especially those at advanced disease stages, receive systemic therapies, including the tyrosine kinase inhibitors sorafenib and lenvatinib. Over the past few years, immune checkpoint inhibitors (ICIs) have changed the landscape of HCC treatment. In particular, the combination therapy with atezolizumab (an anti-PD-L1 antibody) and bevacizumab (an anti-VEGF antibody) significantly improved survival benefits compared with sorafenib as a single agent, a finding that has stimulated further preclinical and clinical development of immunotherapeutic approaches for treating HCC. In addition to ICIs, oncolytic immunotherapy and adoptive T cell therapy have also emerged as immunotherapeutic strategies. A major challenge is that the tumor microenvironment of HCC is usually immunosuppressive, leading to immune escape and immunotherapy resistance. Hence, combination therapies that could sensitize HCC to immunotherapy have become a growing area of investigation. In this review, we summarize recent advances in HCC immuno-oncology and review immunotherapeutic strategies that are under development for treating HCC.
