Drymariamides A-J, Antiadipogenic Cyclopeptides Incorporating Noncanonical Amino Acids from Drymaria cordata.

Herein, we report an extensive phytochemical study on the whole plant of Drymaria cordata, which led to the isolation of ten new orbitides, named drymariamides A-J (1-10). Compounds 2, 3, and 5 incorporate rare residues of noncanonical amino acids of kynurenine (Kyn) or 3a-hydroxypyrroloindoline (HPI). Their structures with absolute configurations were elucidated by a combination of spectroscopic analysis, advanced Marfey's method, X-ray diffraction, and electronic circular dichroism analysis. Compounds 1-10 exhibited antiadipogenic effects in 3T3-L1 adipocytes, and the most potent compound 7 showed an EC50 value of 1.17 ± 0.19 µM.

Association of the Verbal Rating Scale-Measured Dysmenorrhea with Nausea and Vomiting in Pregnancy: A Retrospective Cohort Study.

OBJECTIVES: Nausea and vomiting in pregnancy (NVP) is a common condition that reduces the quality of life by negatively affecting work and family life, physical and mental health, and economic well-being. However, its risk factors remain unclear. This study aimed to explore the association between NVP and verbal rating scale (VRS)-measured dysmenorrhea and to explore potential protective factors. METHODS: This retrospective cohort study was conducted from June 2018 to December 2020 at Tongji Hospital in Wuhan. Information on baseline characteristics, pregnancy-related history, periconceptional micronutrient supplementation, and obstetric outcomes were collected. The severity of dysmenorrhea was assessed using VRS. RESULTS: A total of 443 pregnant women were recruited and divided into the NVP group (n = 76) and the control group (n = 367). A significant association was observed between NVP and VRS-measured dysmenorrhea (c2=10.038, P = 0.007). After adjusting for covariates, the association between moderate/severe dysmenorrhea and NVP remained significant (OR 2.384; 95% CI 1.104-5.148, P = 0.004). First-trimester docosahexaenoic acid supplement (OR 0.443; 95% CI 0.205-0.960, P = 0.039) may be beneficial in reducing the risk of NVP. CONCLUSIONS: Women with moderate to severe dysmenorrhea have a higher risk of experiencing NVP during the first trimester. Periconceptional docosahexaenoic acid supplementation may play a protective role.

Refined Sound Therapy in Combination with Cognitive Behavioural Therapy to Treat Tinnitus: A Randomized Controlled Trial.

Background: Post-auricular injection of lidocaine and methylprednisolone sodium succinate is a commonly used treatment for outpatient patients with tinnitus, but it is invasive, painful and has uncertain efficacy. We need to try to replace it with more non-invasive and effective treatments. The 2014 guidelines of the American Academy of Otolaryngology-Head and Neck Surgery recommend the use of cognitive behavioral therapy (CBT) to treat tinnitus. Some clinical doctors have also attempted sound therapy for tinnitus. It is unclear whether sound therapy combined with CBT y is more effective than local injection of lidocaine and methylprednisolone sodium succinate in treating tinnitus. Objective: To evaluate the efficacy and influencing factors of refined sound therapy combined with CBT in the treatment of tinnitus and compare it with post-auricular injection of lidocaine and methylprednisolone sodium succinate. Methods: We recruited 100 patients with tinnitus; ultimately, 81 patients completed the experiment and underwent follow-up. Patients were randomly assigned to either the treatment group (refined sound therapy combined with CBT) or the control group (post-auricular injections of lidocaine and methylprednisolone sodium succinate). Data was collected from 49 patients in the treatment group and 32 patients in the control group. Pre- and post-treatment data were collected using the Self-Rating Depression Scale (SDS), Hamilton Anxiety Rating Scale (HAM-A), Visual Analogue Score (VAS), Tinnitus loudness and Tinnitus Handicap Inventory (THI) score. Comparisons between groups were performed using the chi-square test, Fisher's exact test, or Wilcoxon rank-sum test. All tests were two-sided and considered statistically significant with P < .05. Results: The THI, SDS and HAM-A scores in the treatment group decreased significantly. In the control group, there was a significant reduction in THI scores, but not in SDS and HAM-A scores. In addition, tinnitus loudness and VAS scores were significantly decreased in the 2 groups. There was a significant difference in the reduction of THI, SDS, HAM-A and VAS scores between the 2 groups; the treatment group showed a greater reduction. However, there was no significant difference in the reduction of tinnitus loudness. There was no statistical difference in the reduction of THI scores, SDS scores, VAS scores and tinnitus loudness in different frequency groups, but there was a statistical difference in the reduction of HAM-A scores. There was no statistical difference in the reduction of THI scores, SDS scores, HAM-A scores, VAS scores and tinnitus loudness between patients with and without hearing loss. Conclusions: (1) This new combination is more effective than post-auricular injection of lidocaine and methylprednisolone sodium succinate in treating tinnitus and improving psychological symptoms. The latter had no effect on improving psychological indicators. (2) With this combination, patients with different tinnitus frequencies experienced different improvements in anxiety. (3) Low-frequency tinnitus seems have been more likely to cause sound adaptation. (4) The improvement in tinnitus and anxiety was the same regardless of whether or not there was hearing loss.

Baccaramiones A-D, Four Highly Oxygenated and Rearranged Trinorditerpenoids from Baccaurea ramiflora.

Baccaramiones A-D (1-4), four highly oxygenated and rearranged trinorditerpenoids, were isolated from Baccaurea ramiflora. Compound 1 is a 1(10 → 5)-abeo-15,16,17-trinor-ent-abietane featuring a unique 5/6/6 spirocyclic scaffold, and 2-4 are the first example of a novel 20(10 → 5)-abeo-15,16,17-trinor-ent-abietane skeleton. Their structures were established by spectroscopic analysis, X-ray crystallography, and electronic circular dichroism calculations. A plausible biosynthetic pathway for 1-4 was proposed. Interestingly, compounds 3 and 4 exhibited significant immunosuppressive activities against concanavalin A-induced T cell proliferation and lipopolysaccharide-induced B cell proliferation in vitro.

Densely Functionalized Macrocyclic Sesquiterpene Pyridine Alkaloids from Maytenus austroyunnanensis.

Eleven densely functionalized new dihydro-ß-agarofuran sesquiterpenoid derivatives, named maytenoids A-K (1-11), as well as one known analog, were isolated and characterized from Maytenus austroyunnanensis. Their structures were assigned based on analysis of spectroscopic data and X-ray crystallography. Compounds 1-9 are macrocyclic sesquiterpene pyridine alkaloids generated by the respective acylation of the hydroxy groups at C-3 and C-13 of dihydro-ß-agarofuran sesquiterpenoids via diverse pyridine dicarboxylic acids. Compounds 1, 2, 5-10, and 12 exhibited significant inhibitory effects on NO production at 10 µM in lipopolysaccharide (LPS)-stimulated BV2 cells.

Multifunctional nanoplatforms application in the transcatheter chemoembolization against hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) has the sixth-highest new incidence and fourth-highest mortality worldwide. Transarterial chemoembolization (TACE) is one of the primary treatment strategies for unresectable HCC. However, the therapeutic effect is still unsatisfactory due to the insufficient distribution of antineoplastic drugs in tumor tissues and the worsened post-embolization tumor microenvironment (TME, e.g., hypoxia and reduced pH). Recently, using nanomaterials as a drug delivery platform for TACE therapy of HCC has been a research hotspot. With the development of nanotechnology, multifunctional nanoplatforms have been developed to embolize the tumor vasculature, creating conditions for improving the distribution and bioavailability of drugs in tumor tissues. Currently, the researchers are focusing on functionalizing nanomaterials to achieve high drug loading efficacy, thorough vascular embolization, tumor targeting, controlled sustained release of drugs, and real-time imaging in the TACE process to facilitate precise embolization and enable therapeutic procedures follow-up imaging of tumor lesions. Herein, we summarized the recent advances and applications of functionalized nanomaterials based on TACE against HCC, believing that developing these functionalized nanoplatforms may be a promising approach for improving the TACE therapeutic effect of HCC.

Effect of statin treatment on mortality in elderly patients with type 2 diabetes mellitus patients: a retrospective cohort study.

BACKGROUND: The effects of statins on the reduction of mortality in individuals aged 75 years or older remain controversial. We conducted this study to investigate whether there is an association between statin therapy and mortality in patients with type 2 diabetes mellitus (T2DM) who are over the age of 75 years. METHODS: The present study used data from the Staged Diabetes Targeting Management Study, which began in 2005. A total of 518 T2DM patients older than 75 years were included. Cox regression analyses were used to evaluate the association between statins and specific causes of death in patients with T2DM. RESULTS: After a follow-up period of 6.09 years (interquartile range 3.94-8.81 years), 111 out of 518 patients died. The results of Cox regression analyses showed that there was no significant association between statin use and all-cause mortality (HR 0.75; 95% CI 0.47, 1.19) after adjustment for all potential confounders. Subgroup analysis indicated that statins had no association with the risk of all-cause mortality or deaths caused by ischemic cardiovascular diseases in T2DM patients with or without coronary heart disease. CONCLUSIONS: Our study found no significant association between all-cause mortality and statin use in T2DM patients over the age of 75 years. More evidence is needed to support the use of statins in the elderly T2DM patients.

Structure-switching aptasensors for sensitive detection of ochratoxin A.

Ochratoxin A (OTA) is a toxic metabolite commonly found in various foods and feedstuffs. Accurate and sensitive detection of OTA is needed for food safety and human health. Based on a common OTA-binding aptamer (OTABA), two structure-switching OTABAs, namely OTABA4 and OTABA3, were designed by configuring a split G-quadruplex and a split G-triplex, respectively, at the two ends of OTABA to construct aptasensors for the detection of OTA. The OTABA, G-quadruplex, and G-triplex all can capture the thioflavin T (ThT) probe, thereby enhancing the fluorescence intensity of ThT. Bonding with OTA could change the conformations of OTABA and G-quadruplex or G-triplex regions, resulting in the release of the captured ThT and diminution of its fluorescence intensity. Dual conformation changes in structure-switching OTABA synergistically amplified the fluorescence signal and improved the sensitivity of the aptasensor, especially for that with OTABA3. The detection limits of the OTABA4-ThT and OTABA3-ThT systems for OTA were 0.28 and 0.059 ng ml-1 , with a 1.4-fold and 6.7-fold higher sensitivity than that of the original OTABA-ThT system, respectively. They performed well in corn and peanut samples and met the requirements of the food safety inspections.

The impact of an integrated PBL curriculum on clinical thinking in undergraduate medical students prior to clinical practice.

BACKGROUND: Problem-based learning (PBL) is a widely adopted educational approach in medical education that aims to promote critical thinking and problem-solving in authentic learning situations. However, the impact of PBL educational mode on undergraduate medical students' clinical thinking ability has been limitedly investigated. This study aimed to assess the influence of an integrated PBL curriculum on clinical thinking ability of medical students prior to clinical practice. METHODS: Two hundred and sixty-seven third-year undergraduate medical students at Nantong University were recruited in this study and were independently assigned to either the PBL or control group. The Chinese version of the Clinical Thinking Ability Evaluation Scale was used to assess clinical thinking ability, and the students' performance in the PBL tutorials was assessed by tutors. All participants in both groups were required to complete the pre-test and post-test questionnaires to self-report their clinical thinking ability. A paired sample t-test, independent sample t-test and one-way analysis of variance test (ANOVA) were used to compare the difference in clinical thinking scores among different groups. Multiple linear regression was conducted to analyze the influencing factors correlated with clinical thinking ability. RESULTS: The clinical thinking ability of most third-year undergraduate medical students at Nantong University was at a high level. The PBL group had a higher proportion of students with high-level clinical thinking ability in the post-test compared to the control group. The pre-test scores of clinical thinking ability were similar between the PBL and control groups, but the post-test scores of clinical thinking ability in the PBL group were significantly higher than those in the control group. Additionally, there was a significant difference in clinical thinking ability between the pre-test and post-test in the PBL group. The post-test scores of sub-scales of critical thinking ability were significantly higher than the pre-test in the PBL group. Furthermore, the frequency of reading literature, time of PBL self-directed learning, and PBL performance score ranking were influencing factors on the clinical thinking ability of medical students in the PBL group. Moreover, there was a positive correlation between clinical thinking ability and the frequency of reading literature, as well as the scores of the PBL performance. CONCLUSIONS: The integrated PBL curriculum model has an active impact on improving undergraduate medical students' clinical thinking ability. This improvement in clinical thinking ability may be correlated with the frequency of reading literature, as well as the performance of the PBL curriculum.

Metal-Enhanced Aggregation-Induced Emission Strategy for the HIV-I RNA-Binding Ligand Assay.

The HIV-Ι trans-activation responsive (TAR) RNA-trans-activator of transcription (Tat) protein complex is crucial for the efficient transcription of the integrated human immunodeficiency virus-I genome and is an established therapeutic target for AIDS diagnosis and treatment. Developing a sensitive strategy for the TAR RNA-binding ligand assay could provide antiviral leads with a radically new mechanism for the treatment of AIDS. Herein, a new TAR RNA-binding ligand assay platform was established using a signal amplification strategy that combines aggregation-induced emission (AIE) with a metal-enhanced fluorescence (MEF) concept. The tetraphenylethylene (TPE) derivative was labeled on the Tat peptide as a fluorescent molecule, while the TAR RNA was immobilized on the surface of the Fe3O4@Au@Ag@SiO2 nanoparticles (NPs) to specifically bind the TPE-Tat peptide. The TPE-Tat peptide was weakly emissive itself while emitting strongly in the NP-TAR-TPE-Tat complex by the AIE and MEF signal amplification effect. It was confirmed by known Tat peptide competitors that this system could be applied to the screening and detection of TAR RNA-binding ligands because they could replace the TPE-Tat peptide from the complex and make the system fluorescence decrease. When this system was adopted to test four candidate ligands, it was found that bisantrene had a favorable TAR RNA-binding ability. The proposed AIE-MEF strategy not only provides a sensitive and reliable method for the TAR RNA-binding ligand assay but also can avoid the influence of ligands on fluorescent detection in the conventional displacement assay.

Dolabrane-Type Diterpenoids with Immunosuppressive Activity from Koilodepas hainanense.

Thirteen new dolabrane-type diterpenoids, koilodenoids A-M (1-13), including a chlorinated congener (2), along with six known analogues, were isolated from Koilodepas hainanense. The structures were determined by analysis of spectroscopic data, ECD spectra, and X-ray crystallographic studies. The absolute configuration of C-15 in the 15,16-diol unit of compounds 4 and 5 was established by using the dimolybdenum tetraacetate [Mo2(AcO)4]-induced ECD method. Compounds 4, 7, 16, 17, and 19 showed moderate to significant immunosuppressive activities against the proliferation of T and B lymphocytes in vitro, with compound 16 being the most potent (IC50 0.86 and 0.29 µM, respectively).

HNRNPU promotes the progression of hepatocellular carcinoma by enhancing CDK2 transcription.

The nuclear matrix-associated protein Heterogeneous Nuclear Ribonucleoprotein U (HNRNPU), also known as SAF-A, is known to maintain active chromatin structure in mouse hepatocytes. However, the functional roles and molecular mechanisms of HNRNPU in the development of hepatocellular carcinoma (HCC) remain largely unknown. Herein, we found that HNRNPU was upregulated in HCC, and the proliferation of HCC cells was inhibited in vitro and in vivo upon HNRNPU knockdown. Moreover, the upregulation of HNRNPU was correlated with poor prognosis in HCC. Mechanistically, HNRNPU bound to the CDK2 gene locus, a key factor in cell cycle regulation, where it was enriched with H3K27 acetylation (H3K27ac), H3K9 acetylation (H3K9ac), and H3K4 mono-methylation (H3K4me1). Furthermore, HNRNPU knockdown reduced the levels of H3K27ac and H3K9ac at the binding site, where the levels of H3K27 tri-methylation (H3K27me3) were increased, eventually leading to the downregulation of CDK2. Collectively, our results provide a new mechanism whereby HNRNPU promotes HCC development by enhancing the transcription of CDK2.

Determination of trans-fatty acids in food samples based on the precolumn fluorescence derivatization by high performance liquid chromatography.

Trans-fatty acids are unsaturated fatty acids that are considered to have health risks. 1,3,5,7-Tetramethyl-8-butyrethylenediamine-difluoroboradiaza-s-indacene is a highly sensitive fluorescent labeling reagent for carboxylic acids developed by our lab. In this study, using this precolumn fluorescent derivatization reagent, a rapid and accurate high-performance liquid chromatography with fluorescence detection method was developed for the determination of two trans-fatty acids in food samples. Under the optimized derivative conditions, two trans-fatty acids were tagged with the fluorescent labeling reagent in the presence of 1-ethyl-3-(3-dimethyl-aminopropyl) carbodiimide at 25°C for 30 min. Then, the baseline separation of trans- and cis-fatty acids and their saturated fatty acid with similar structures was achieved with less interference using a reversed-phased C18 column with isocratic elution in 14 min. With fluorescence detection at λex /λem  = 490 /510 nm, the linear range of the TFAs was 1.0-200 nM with low detection limits in the range of 0.1-0.2 nM (signal-to-noise ratio = 3). In addition, the proposed approach was successfully applied for the detection of trans-fatty acids in food samples, and the recoveries using this method ranged from 96.02 to 109.22% with low relative standard deviations of 1.2-4.3% (n = 6).

The association between the serum uric acid to creatinine ratio and all-cause mortality in elderly hemodialysis patients.

BACKGROUND: Elderly hemodialysis patients have a higher rate of mortality than nonelderly hemodialysis patients. Recent studies shown that the serum uric acid to creatinine ratio (SUA/Scr) was associated with all-cause mortality in general adults. The purpose of the present study was to investigate the association between the SUA/Scr and all-cause and cardiovascular disease mortality among elderly hemodialysis patients. METHODS: A total of 222 patients (≥ 60 years) who received hemodialysis more than 8 h per week at Taizhou Second People's Hospital for at least 3 months were enrolled in the present study from January 2015 to December 2019. Clinical characteristics including age, sex and height et. al, were obtained from the hemodialysis database. The laboratory data, including albumin (ALB), total cholesterol (TC), serum uric acid (SUA), serum creatinine (Scr) and so on, were collected before hemodialysis and analyzed by automatic biochemical analyzer. Survival information was recorded during the follow-up period. Multiple Cox regression was carried out to analyze the association between SUA/Scr and all-cause mortality. The survival rate of each group was calculated by the Kaplan-Meier method, and the ratio of survival curves was analyzed by the log-rank test. The contribution of SUA/Scr for predicting all-cause mortality risk was evaluated by net reclassification improvement (NRI). RESULTS: During the 19-month observation period, 78 patients died. Individuals in the nonsurviving group had significantly older ages (P < 0.001), body mass index (BMI) (P = 0.004), serum creatinine (P = 0.005) and prealbumin (P = 0.006) than surviving patients. After adjusting for age, sex, BMI, prealbumin, dialysis vintage, dialysis frequency, single-pool Kt/V (spKt/V), DM, hypertension and comorbidities, a higher ratio of SUA/Scr was independently associated with a higher risk of all-cause mortality (HR: 1.292; 95% CI: 1.013-1.648; P = 0.039). The predict value on all-cause mortality of SUA/Scr was superior to SUA (additive NRI = 0.214, P = 0.015) and Scr (additive NRI = 0.476, P < 0.001) among elderly hemodialysis patients. CONCLUSION: The serum uric acid to creatinine ratio is strongly associated with all-cause mortality in elderly hemodialysis patients which is more predictive than SUA or Scr alone.

[Representations of object animacy and real-world size in the ventral visual pathway].

How the brain perceives objects and classifies perceived objects is one of the important goals of visual cognitive neuroscience. Previous research has shown that when we see objects, the brain's ventral visual pathway recognizes and classifies them, leading to different ways of interacting with them. In this paper, we summarize the latest research progress of the ventral visual pathway related to the visual classification of objects. From the perspective of the neural representation of objects and its underlying mechanisms in the visual cortex, we summarize the current research status of the two important organizational dimensions of object animacy and real-world size, provide new insights, and point out the direction of further research.

[Testosterone replacement therapy improves metabolic indexes of the patients with hypogonadism: A meta-analysis].

OBJECTIVE: To systematically evaluate the effect of testosterone replacement therapy (TRT) on metabolic indexes in patients with hypogonadism. METHODS: We searched the databases of CNKI, CBM, Wanfang Data, VIP, PubMed, Medline, Embase and Cochrane Library from the establishment to May 2021 for clinical randomized controlled trials (RCT) on the improvement of metabolic indexes of the patients with hypogonadism treated by TRT. According to the inclusion and excretion criteria, we screened the literature, extracted the data and evaluated the quality of the included RCTs, followed by statistical analysis with the STATA15.1 software. RESULTS: Totally 19 RCTs with 1 553 cases were included. Compared with placebo, TRT effectively reduced the levels of fasting plasma glucose (FPG) and fasting insulin (FINS), improved Homeostatic Model Assessment-insulin resistance (HOMA-IR), decreased total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), increased the body mass index (BMI), lowered the waist circumference (WC), but elevated the systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the patients. No statistically significant differences were observed in the improvement of glycosylated hemoglobin (HbA1c) and triglyceride (TG) between the TRT-treated patients and placebo controls. The results of Egger's and Begg's tests showed no significant publication bias among the studies. CONCLUSION: TRT can significantly improve metabolic indexes in patients with hypogonadism, though further studies are needed to confirm its long-term efficacy and safety in patients with metabolic disorders.

Ionizing Radiation Combined with PARP1 Inhibitor Reduces Radioresistance in Prostate Cancer with RB1/TP53 Loss.

Tumor suppressor genes RB1 and TP53 are altered frequently in prostate cancer (PC), whether RB1 and TP53 inactivation promotes radioresistance remains unclear. Herein, we demonstrated that RB1 loss enhanced ionizing radiation (IR)-induced DNA damage to inhibit cell proliferation and promote cellular senescence through a TP53-dependent pathway in LNCaP cells. Furthermore, the stabilization of TP53 was regulated by ATM-mediated phosphorylation of MDM2 at Ser395. However, inactivation of RB1/TP53 reversed DNA damage-induced cellular senescence and promoted radiation survival. Importantly, combined with PARP1 inhibitor restored radiosensitivity. This finding provides a potential approach for the therapy of PC with RB1/TP53 inactivation.

Accurate quantitative phase imaging by the transport of intensity equation: a mixed-transfer-function approach: erratum.

In this erratum, we correct Fig. 4 of our Letter [Opt. Lett.46, 1740 (2021)OPLEDP0146-959210.1364/OL.422095]. This does not change the scientific conclusions of the original Letter.

Accurate quantitative phase imaging by the transport of intensity equation: a mixed-transfer-function approach.

As a well-established deterministic phase retrieval approach, the transport of intensity equation (TIE) is able to recover the quantitative phase of a sample under coherent or partially coherent illumination with its through-focus intensity measurements. Nevertheless, the inherent paraxial approximation limits its validity to low-numerical-aperture imaging and slowly varying objects, precluding its application to high-resolution quantitative phase imaging (QPI). Alternatively, QPI can be achieved by phase deconvolution approaches based on the coherent contrast transfer function or partially coherent weak object transfer function (WOTF) without invoking paraxial approximation. But these methods are generally appropriate for "weakly scattering" samples in which the total phase delay induced by the object should be small. Consequently, high-resolution high-accuracy QPI of "nonweak" phase objects with fine details and large phase excursions remains a great challenge. In this Letter, we propose a mixed-transfer-function (MTF) approach to address the dilemma between measurement accuracy and imaging resolution. By effectively merging the phases reconstructed by TIE and WOTF in the frequency domain, the high-accuracy low-frequency phase "global" profile can be secured, and high-resolution high-frequency features can be well preserved simultaneously. Simulations and experimental results on a microlens array and unstained biological cells demonstrate the effectiveness of MTF.

Loading-induced antitumor capability of murine and human urine.

While urine has been considered as a useful bio-fluid for health monitoring, its dynamic changes to physical activity are not well understood. We examined urine's possible antitumor capability in response to medium-level, loading-driven physical activity. Urine was collected from mice subjected to 5-minute skeletal loading and human individuals before and after 30-minute step aerobics. Six cancer cell lines (breast, prostate, and pancreas) and a mouse model of the mammary tumor were employed to evaluate the effect of urine. Compared to urine collected prior to loading, urine collected post-activity decreased the cellular viability, proliferation, migration, and invasion of tumor cells, as well as tumor weight in the mammary fat pad. Detection of urinary volatile organic compounds and ELISA assays showed that the loading-conditioned urine reduced cholesterol and elevated dopamine and melatonin. Immunohistochemical fluorescent images presented upregulation of the rate-limiting enzymes for the production of dopamine and melatonin in the brain. Molecular analysis revealed that the antitumor effect was linked to the reduction in molecular vinculin-linked molecular force as well as the downregulation of the Lrp5-CSF1-CD105 regulatory axis. Notably, the survival rate for the high expression levels of Lrp5, CSF1, and CD105 in tumor tissues was significantly lowered in the Cancer Genome Atlas database. Collectively, this study revealed that 5- or 10-minute loading-driven physical activity was sufficient to induce the striking antitumor effect by activating the neuronal signaling and repressing cholesterol synthesis. The result supported the dual role of loading-conditioned urine as a potential tumor suppressor and a source of diagnostic biomarkers.
