TFIIB-related factor 1 (BRF1) is an important transcription factor. It specifically regulates the transcription of RNA polymerase III-dependent genes (RNA Pol III genes). The products of these genes are some small non-coding RNAs, including transfer RNAs (tRNAs) and 5S ribosomal RNAs (5S rRNA). The transcription levels of tRNAs and 5S rRNA vary with changes in intracellular BRF1 amounts. tRNAs and 5S rRNA play a crucial role in determining protein synthesis. Studies have demonstrated that dysregulation of tRNAs and 5S rRNA is closely related to cell growth, proliferation, transformation, and even tumorigenesis. BRF1 is a key factor determining the generation of tRNAs and 5S rRNA. Increasing BRF1 expression enhances cell proliferation and transformation, promoting tumor development. In contrast, repressing BRF1 activity decreases the rates of cell proliferation and transformation, and inhibits tumor growth. High levels of BRF1 are found in the samples of patients suffering from hepatocellular carcinoma, breast cancer, gastric carcinoma, lung cancer, prostate carcinoma, and other cancers. It indicates that high levels of BRF1 are closely related to the occurrence of human cancer and may be a common landmark of tumors. But there is discrepancy in the regulatory mechanisms and signaling pathways of BRF1 overexpression in different cancers. In general, high levels of BRF1 in patients suffering from cancer show short survival period and poor prognosis. However, there is one exception, namely breast cancer. Approximate 80% of cases of breast cancer are estrogen receptor-positive (ER+) and 20% are ER-. The cases with high levels of BRF1 reveal longer survival period and better prognosis after they accepted the hormone treatment by Tamoxifen (Tam), compared to the cases with low level BRF1. It seems like a contradiction. Most of the cases with high levels of BRF1 belong to ER+ status. Tam has been used to treat ER+ cases of breast cancer after diagnosis and surgery. Thus, hormone therapy, such as Tam, is more effective on these patients. This is because, on one hand, that Tam competes with E2 (17β-estradiol) to bind to estrogen receptor α (ERα), but does not dissociate to occupy the receptors, blocking E2 binding to this receptor and inhibiting its biological effects. On other hand, Tam can inhibit the expression of BRF1, leading to a decline of intracellular BRF1 levels. Therefore, the actual levels of BRF1 are lower in the patients with ER+ breast cancer. It appears the prognosis of the high BRF1 expression cases better than that of the low BRF1 expression cases. Myocardial hypertrophy manifests magnification of cardiomyocyte volume rather than number increasing in the postnatal heart. Myocardial hypertrophy is a critical risk factor underlying cardiovascular diseases. No matter how myocardial hypertrophy occur, it will ultimately lead to myocardial dysfunction and heart failure. Hypertrophic growth of cardiomyocytes requires a large amount of protein synthesis to meet its needs of cardiomyocyte growth. Animal models and cell experiments have shown that myocardial hypertrophy stimulates a significant increase in BRF1 expression and transcription of tRNAs and 5S rRNA. Interestingly, elevated levels of BRF1 are found in the myocardium tissues of patients with myocardial hypertrophy. These studies demonstrate that BRF1 indeed plays a critical role in myocardial hypertrophy. In summary, high levels of BRF1 are found in patients suffering from different cancers and myocardial hypertrophy. It implies that BRF1 is a promising biological target of cancer and cardiomyopathy. BRF1 is expected to become a common biomarker for early diagnosis and prognostic observation of different human cancers. It is also an important biomarker for the diagnosis and treatment of cardiomyopathy. BRF1 not only holds an important position in the field of basic medical research but also has great prospects for translational medicine. In the present article, we summarize the progress on studies of BRF1 expressions in cancer and cardiomyopathy, proposes future research directions. It is a new research area. Here, we emphasize the significancy of BRF overexpression in the two huge diseases of human, cancer and cardiomyopathy to raise people's attention to this field.

To investigate the pharmacological substances basis and anti-vitiligo mechanism of Carum carvi L. (caraway) fruits, chemical and blood-absorbed components were identified using mass spectrometry combined with literature study and database analysis. A “blood-absorbed components–target genes–pathways” network was constructed through network pharmacology. The pharmacological effects of Carum carvi L. extract and its key blood-absorbed component, acacetin, were validated in vitro. 72 chemical components were identified in the extract, with 11 prototype blood-absorbed components and 26 metabolites being detected in the plasma of SD rats. 14 key active components and 24 key targets were predicted. In vitro experiments demonstrated that acacetin at 10 μmol/L exhibited melanogenesis-promoting and tyrosinase-activating effects compared with the positive control, significantly upregulating the expression of microphthalmia-associated transcription factor (MITF) and tyrosinase (tyrosinase, TYR). This study comprehensively analyzes the chemical and blood-absorbed components of Carum carvi L. and elucidates its pharmacological substances basis, which provides a theoretical foundation for the anti-vitiligo effects of acacetin.

Objective:To systematically evaluate the global disease burden of neonatal sepsis and other neonatal infections(NSNIs),providing scientific basis for their prevention and control.Methods:Using the Global Burden of Disease(GBD)2021 database,this article calculated the incidence,mortality,and age-standardized rates for NSNIs. Trends were evaluated with Joinpoint regression model,and compared at different socio-demographic index(SDI)levels.Results:From 1990 to 2021,the global age-standardized incidence rate(ASIR)of NSNIs decreased from 78.98 to 62.70 per 100 000 with an with average annual percentage change(AAPC)of -0.73%( P<0.01). The age-standardized mortality rate(ASMR)declined from 4.77 to 3.76 per 100 000 with an AAPC of -0.76%( P<0.01). In particular,the disease burden was consistently higher among male neonates. Low birth weight was the primary risk factor globally,followed by preterm birth. Regions with lower SDI levels exhibited higher ASIR and ASMR,and household solid fuel air pollution contributed more to NSNIs-related mortality. Conclusion:Although the overall disease burden of NSNIs has declined,male neonates and low-SDI regions still face substantial challenges. Continuous efforts to improve air quality are warranted,and low-SDI regions should further strengthen healthcare infrastructure to enhance diagnostic and treatment quality.

Objective To study the dynamic regulatory role of early growth response 4(EGR4)in mouse neurodevelopment.Methods Data on single-cell chromatin accessibility(single-cell assay for transposase-accessible chromatin by sequencing,scATAC-seq)and transcriptome(single-cell RNA sequencing,scRNA-seq)from seven key stages spanning from the embryonic period to adulthood was collected and analyzed.The transcription factor binding site network was inferred,a quantitative analysis from a temporal perspective was conducted,its functional modules were parsed,and the results were visualized.Results egr4 was significantly highly expressed from the late embryonic stage to adulthood,and specifically activated during the maturation of inhibitory neurons[parvalbumin(PV)and somatostatin(SST)subtypes].Moreover,its transcription was not directly regulated by changes in chromatin accessibility.Temporal network analysis indicated that EGR4 became a regulatory hub in the late embryonic stage and drove neuron differentiation and subtype specification.Functional enrichment analysis showed that EGR4 regulated the"cell differentiation"pathway through dynamic interacting factors,and there were subtype-specific interaction modules in PV/SST neurons respectively.Conclusion EGR4 can participate in the late-stage maturation of cortical neurons through a stage-specific regulatory network.This study provides a new perspective on mechanisms underlying the temporal logic of neural development.

Objective:To investigate the clinical efficacy and safety of deep hyperthermia combined with sintilimab and nab-PC (albumin-bound paclitaxel + carboplatin) regimen in the treatment of advanced squamous non-small cell lung cancer (NSCLC) with driver gene negative and programmed death-1 receptor ligand 1 (PD-L1) expression positive.Methods:A prospective case-control study was performed. A total of 84 advanced squamous NSCLC patients with driver gene negative and PD-L1 expression positive in Hebei Seventh People's Hospital from January 2020 to December 2022 were collected, and all patients were divided into the observation group and the control group according to the random number table method, with 42 cases in each group. The control group was given the treatment of sintilimab combined with nab-PC regimen, and the observation group was given deep hyperthermia on the basis of the control group. After 4 consecutive cycles of treatment, the short-term efficacy of the two groups was compared. The levels of serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA), cytokeratin fragment 19 (CYFR21-1)], and the positive expression rates of immunohistochemistry markers [p40, p63, and cytokeratin 5/6 (CK5/6)] before and after treatment were compared between two groups. Functional Assessment of Cancer Therapy-Lung cancer module (FACT-L) scores, the adverse reactions and the long-term survival of the two groups were compared.Results:There were 26 males and 16 females in the observation group, and the age was (59±11) years; there were 22 males and 15 females in the control group, and the age was (58±11) years. The objective remission rate and the disease control rate were 71.43% (30/42), 90.48% (38/42), respectively in the observation group, and 50.00% (21/42), 80.95% (34/42), respectively in the control group; the objective remission rate in the observation group was higher than that in the control group, and the difference was statistically significant ( χ2 = 4.04, P = 0.044); and there was no statistically significant difference in the disease control rate of both groups ( χ2 = 1.56, P = 0.212). The levels of serum CEA, SCCA and CYFRA21-1, and the positive expression rates of p40, p63, and CK5/6 in the two groups after treatment were lower than those before treatment (all P < 0.05); and the scores of physiological status, functional status, additional concern in FACT-L scores and the total score of the scale after treatment were higher than those before treatment (all P < 0.05). There were no statistically significant differences in the incidence of adverse reactions including thrombocytopenia, neutropenia, leukopenia, anemia, fever of the two groups (all P > 0.05). The median progression-free survival (PFS) time was 6.5 months (95% CI: 3.82-12.75), 5.1 months (95% CI: 3.14-12.26),respectively in the observation group and the control group, and the difference in the median PFS time was statistically significantly of both groups ( χ2 = 4.21, P = 0.040). The median overall survival (OS) time was 12.9 months (95% CI: 6.25-15.46), 9.7 months (95% CI: 4.74-13.02), respectively in the observation group and the control group, and the difference in the median OS time was statistically significantly of both groups ( χ2 = 4.43, P = 0.035). Conclusions:Deep hyperthermia combined with sintilimab and nab-PC regimen in the treatment of advanced squamous NSCLC with driver gene negative and PD-L1 expression positive can effectively reduce the serum tumor markers levels and positive expression rate of immunohistochemical markers, improve the quality of life of patients, and increase the short-term and long-term efficacy.
