PeerJ 2024; 12:e17642. [PMID: 38978754 PMCID: PMC11229682 DOI: 10.7717/peerj.17642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Accepted: 06/06/2024] [Indexed: 07/10/2024] Open
Abstract
Background Gingivitis is an inflammation of the gums that is the initial cause of the development of periodontal disease by the activity of Nuclear Factor-kappa B (NF-κB), Interleukin-1β (IL-1β), Interleukin-6 (IL-6), p38, and Tumor Necrosis Factor-α (TNF-α). Unaddressed chronic inflammation can lead to persistent disturbances in other parts of the body. Brazilin is a naturally occurring plant chemical that may have antibacterial and anti-inflammatory effects. Treatment based on the natural plant compound, brazilin, is developed in the form of a topical cream for easy application. Objective The aim is to develop the natural compound brazilin in the form of a topical cream as an anti-inflammatory agent to reduce NF-κB expression through Imunohistochemistry (IHC) methods, and the expression of pro-inflammatory genes IL-1β, IL-6, p38, and TNF-α. Methods Male Sprague-Dawley rats were induced with gingivitis using P. gingivalis bacteria. The observed groups included rats treated with a single application of brazilin cream and rats treated with two applications of brazilin cream. The treatment was administered for 15 days. On days 3, 6, 9, 12, and 15, anatomical wound observations and wound histology using hematoxylin-eosin and Masson's Trichrome staining were performed. NF-κB protein expression was analyzed using the IHC method. Gingival inflammation gene expression of NF-κB, IL-1β, IL-6, p38, and TNF-α was measured using q-RTPCR. Results Single and double applications of brazilin cream increased angiogenesis and decreased NF-κB protein expression, in addition to the IL-1β, IL-6, p38, and TNF-α gene expressions. Conclusion In a rat gingivitis model, Brazilin cream may function as an anti-inflammatory agent in the gingival tissue.

Abstract
Cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) synthase (cGAS) is a DNA sensor that elicits a robust type I interferon response by recognizing ubiquitous danger-associated molecules. The cGAS/stimulator of interferon genes (cGAS/STING) is activated by endogenous DNA, including DNA released from mitochondria and extranuclear chromatin, as well as exogenous DNA derived from pathogenic microorganisms. cGAS/STING is positioned as a key axis of autoimmunity, the inflammatory response, and cancer progression, suggesting that the cGAS/STING signaling pathway represents an efficient therapeutic target. Based on the accumulated evidence, we present insights into the prevention and treatment of cGAS/STING-related chronic immune and inflammatory diseases. This review presents the current state of clinical and nonclinical development of modulators targeting cGAS/STING, providing useful information on the design of therapeutic strategies.

Abstract
BACKGROUND Occupational contact dermatitis (OCD) is a skin disorder caused by contact with any substances found in the workplace. Occupational contact dermatitis is second most common occupational disease (15% of all cases of occupational disease). Occupational contact dermatitis is divided into allergic contact dermatitis (ACD) and irritant contact dermatitis (ICD) which is 80% of cases that affects hands. Batik is an art that is painted on cloth, it is one of Indonesian cultural heritage. Batik workers have a higher risk of obtaining OCD due to exposure to chemicals and fluids used during work. Natural dyes used in the dyeing process are less likely to cause ACD than standard allergens. Some of the natural dyes used in the dyeing process in batik industries are Indigofera tinctoria, sappan wood (Caesalpinia sappan), and Mahagony (Swietenia mahagoni) cause skin sensitisation. OBJECTIVE To compare the results of patch testing between natural dyes (Indigofera tinctoria, sappan wood (Caesalpinia sappan), and Mahagony (Swietenia mahagoni) with standard allergens (p-phneyldiamine 0.1%, potassium dichromate 0.5% and formaldehyde 0.1%) as a cause of ACD in batik workers in Surakarta, East Java, Indonesia. METHOD A cross-sectional study was conducted on 63 subjects batik workers with OCD in Surakarta, East Java, Indonesia. Subjects were patch tested with three standard allergens (p-phenylenediamine 0.1%, potassium dichromate 0.5%, and formaldehyde 1%) and natural dyes (Indigofera tinctoria, sappan wood (Caesalpinia sappan), and Mahagony (Swietenia mahagoni). A closed patch test was evaluated 48 and 96 hour later. Screening of OCD in batik workers in Surakarta, East Java, Indonesia was based on Nordic Occupational Skin Questionnaire NOSQ-2002, and diagnosis of OCD was based on Mathias criteria (at least 4 out of 7 criteria were met). Data were analysed using a non-parametric Chi-square test with SPSS 21 with a significant difference if the p-value < 0.05. RESULT Natural dyes significantly caused allergic contact dermatitis in batik workers in Surakarta, East Java, Indonesia than standard allergens (p = 0.016). A positive patch test was found in 11 patients, standard allergen p-phenylenediamine (PPD) 0.1% was seen on one patient, potassium dichromate 0.5% on two patients, and formaldehyde 1% on two patients. A positive patch test using Indigofera tinctoria was found at one patient, sappan wood (Caesalpinia sappan) in three patients, and Mahagony (Swietenia mahagoni) in five patients. CONCLUSION Natural dyes cause more positive patch test results in batik workers.

Abstract
Glioblastoma, an aggressive brain cancer, demonstrates the least life expectancy among all brain cancers. Because of the regulation of diverse signaling pathways in cancers, the chemotherapeutic approaches used to suppress their multiplication and spreading are restricted. Sensitivity towards chemotherapeutic agents has developed because of the pathological and drug-evading abilities of these diverse mechanisms. As a result, the identification and exploration of strategies or treatments, which can overcome such refractory obstacles to improve glioblastoma response to treatment as well as recovery, is essential. Medicinal herbs contain a wide variety of bioactive compounds, which could trigger aggressive brain cancers, regulate their anti-cancer mechanisms and immune responses to assist in cancer elimination, and cause cell death. Numerous tumor-causing proteins, which facilitate invasion as well as metastasis of cancer, tolerance of chemotherapies, and angiogenesis, are also inhibited by these phytochemicals. Such herbs remain valuable for glioblastoma prevention and its incidence by effectively being used as anti-glioma therapies. This review thus presents the latest findings on medicinal plants using which the extracts or bioactive components are being used against glioblastoma, their mechanism of functioning, pharmacological description as well as recent clinical studies conducted on them.

CURRENT RESEARCH IN PHARMACOLOGY AND DRUG DISCOVERY 2021; 2:100059.

Abstract
The barrier-to-autointegration factor 1 (BAF1) protein is a DNA-binding protein implicated in nuclear envelop repair and reformation after mitosis. This nuclear protein is frequently overexpressed in cancer cells and plays a role in the occurrence and development of different tumors. It is a potential therapeutic target for gastric cancer, breast cancer and other malignancies. For this reason, BAF1 inhibitors are searched. The butanolide lactone obtusilactone B (Ob-B) has been found to inhibit VRK1-dependent phosphorylation of BAF1, upon direct binding to the nuclear protein. Taking advantage of the known crystallographic structure of BAF1, we have elaborated molecular models of Ob-B bound to BAF1 to delimit the binding site and binding configuration. The long endoolefinic alkyl side chain of Ob-B extends into a small groove on the protein surface, and the adjacent exomethylene-γ-lactone moiety occupies a pocket comprising to the Ser-4 phosphorylation site of BAF1. Twenty butanolide lactones structurally close to ObB were screened for BAF1 binding. Several natural products with BAF1-binding capacity potentially superior to Ob-B were identified, including mahubanolide, kotomolide B, epilitsenolide D2, and a few other known anticancer plant natural products. Our study provides new ideas to guide the discovery and design of BAF1 inhibitors. Obtusilactone B (Ob-B) is an anticancer inhibitor of VRK1-mediated BAF1 phosphorylation. Molecular models of Ob-B bound to BAF1 have been constructed and the binding site determined. Screening of 20 butanolide lactones led to the identification of new potential BAF1 binders. Mahubanolide, kotomolide B and epilitsenolide D2 emerge as potential BAF1 inhibitors.

Abstract
DNA immune recognition regulation mediated by the cGAS-STING pathway plays an important role in immune functions. Under normal physiological conditions, cGAS can recognize and bind to invading pathogen DNA and activate the innate immune response. On the other hand, abnormal activation of cGAS or STING is closely related to autoimmune diseases. In addition, activation of STING proteins as a bridge connecting innate immunity and adaptive immunity can effectively restrain tumor growth. Therefore, targeting the cGAS-STING pathway can alleviate autoimmune symptoms and be a potential drug target for treating cancer. This article summarizes the current progress on cGAS-STING pathway modulators and lays the foundation for further investigating therapeutic development in autoimmune diseases and tumors.

Abstract
Caesalpinia sappan and Haematoxylum brasiletto belong to the Fabaceae family, predominantly distributed in Southeast Asia and America. The isoflavonoid brazilin has been identified from the bark and heartwood of these plants. This review summarizes the studies describing the biological activities of these plants and brazilin. Mainly, brazilin protects cells from oxidative stress, shows anti-inflammatory and antibacterial properties, and hypoglycemic effect. In addition, it has a biological impact on various pathologies such as Alzheimer's disease, Parkinson's disease, fibrillogenesis, and osteoarthritis. Interestingly, most of the antecedents are related to the anticancer effect of brazilin. In several cancers such as osteosarcoma, neuroblastoma, multiple myeloma, glioblastoma, bladder, melanoma, breast, tongue, colon, cervical, head, and neck squamous cell carcinoma, brazilin induces autophagy by increasing the levels of the LC3-II protein. Furthermore, it inhibits cell proliferation and induces apoptosis through increased expression of Bcl-2, Bcl-XL, p21, p27, activation of caspase-3 and -7, and the cleavage of PARP and inhibiting the expression of Bax. In addition, it blocks the expression of JNK and regulates the nuclear translocation of Nrf2. Together, these data positions brazilin as a compound of natural origin with multiple bioactivities and therapeutic potential in various chronic degenerative diseases and cancer.

[PMID: 34257693 PMCID: PMC8257350 DOI: 10.1155/2021/9939345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 05/17/2021] [Accepted: 06/18/2021] [Indexed: 11/23/2022]
Abstract
AIM Traditionally, C. sappan medicine was the heartwood, which needs to be cut down as a whole. In this research, the antitumor activity and mechanisms of the leaves and stems were compared with the roots of Caesalpinia sappan; it was in order to investigate whether stems and leaves of C. sappan could be used to replace heartwood for antitumor treatment, thereby reducing resource destruction. METHODS MTT assays were used to identify the active sites of C. sappan based on the application of human liver cancer (HuH-7) cells. High-performance liquid chromatography (HPLC) was used to analyze polar extracts. We also established a H22 hepatoma-bearing mouse model by administering intraperitoneal injections of petroleum ether extracts from the leaves and stems (SY②) at doses of 20 and 65 mg/kg. Mice in the i.g. group were administered intragastrically with the same extracts (at doses of 100 and 325 mg/kg) at the same time (12 days). RESULTS The antitumor site of C. sappan was the petroleum ether extract. The IC50 for the petroleum ether extract of roots (SG②) was 56.10 μg/ml, while that for the leaves and stems (SY②) was 77.20 μg/ml. Grey relational analysis indicated 11 active fraction peaks that were closely related to antitumor activity. The size of tumors in H22 hepatoma-bearing mice was reduced significantly in mice administered with petroleum ether extracts from the leaves and stems (inhibition rates of high doses were 55.31% and 60.56%). Fibrous tissue proliferation, inflammatory cell infiltration, tumor cell necrosis, and the expression of proliferating cell nuclear antigen (PCNA) and vascular endothelial growth factor (VEGF) were all lower than in the control group (VEGF P < 0.001 and PCNA P < 0.05). CONCLUSION Petroleum ether extracts of the roots, leaves, and stems of C. sappan exhibit certain antitumor effects. Our data indicate that the mechanisms underlying these effects may relate to a reduction in the expression of PCNA and VEGF and the inhibition of angiogenesis. Our findings indicate that we can expand the medicinal use of C. sappan to the leaves and stems, thus improving resource utilization and reducing resource damage.

Abstract
Glioblastoma multiforme, an intrusive brain cancer, has the lowest survival rate of all brain cancers. The chemotherapy utilized to prevent their proliferation and propagation is limited due to modulation of complex cancer signalling pathways. These complex pathways provide infiltrative and drug evading properties leading to the development of chemotherapy resistance. Therefore, the development and discovery of such interventions or therapies that can bypass all these resistive barriers to ameliorate glioma prognosis and survival is of profound importance. Medicinal plants are comprised of an exorbitant range of phytochemicals that have the broad-spectrum capability to target intrusive brain cancers, modulate anti-cancer pathways and immunological responses to facilitate their eradication, and induce apoptosis. These phytocompounds also interfere with several oncogenic proteins that promote cancer invasiveness and metastasis, chemotherapy resistance and angiogenesis. These plants are extremely vital for promising anti-glioma therapy to avert glioma proliferation and recurrence. In this review, we acquired recent literature on medicinal plants whose extracts/bioactive ingredients are newly exploited in glioma therapeutics, and also highlighted their mode of action and pharmacological profile.

Abstract
The protein barrier-to-autointegration factor (BAF) and its interaction partners, the LEM (LAP2B, emerin, MAN1)-domain proteins, constitute a powerful cytoplasmic DNA defense mechanism. Invading DNA molecules are quickly bound by the BAF system and trapped in membrane compartments. This decreases the nuclear uptake of DNA from the cytoplasm. Inhibition of the BAF system is therefore expected to enhance the efficacy of non-viral DNA transfection agents. In this study, we introduced a protocol for the recombinant expression of soluble BAF and developed two ELISA-type assays to discover small molecule inhibitors of BAF-dependent DNA retention by high throughput screening (HTS). The proton pump inhibitor rabeprazole as well as three compounds of the Maybridge library were identified as inhibitors of the LEM-BAF-DNA interaction chain. The inhibition was based on adduct formation with BAF cysteine residues. An enhancing effect of the compounds on cell culture transfection, however, was not observed, which may be attributed to the reducing environment of the cytoplasm that prevents the adduct formation with BAF cysteine residues. The novel assays developed here can provide new tools to further study the biological functions of the BAF system, and may lead to the identification of suitable BAF inhibitors in future HTS campaigns.

Abstract
Heme oxygenase-1 (HO-1) is highly induced in various human disease states, including cancer, indicating that HO-1 is an emerging target of cancer therapy. In this study, we investigated that the mechanisms of hemin-induced HO-1 expression and its signaling pathways in human breast cancer cell. We used MCF-7 cells, a human breast cancer cell line. Hemin increased HO-1 expression in MCF-7 cells in a dose- and time-dependent manner. Hemin enhanced HO-1 expression through the activation of c-Jun N-terminal kinases (JNK) signaling pathway. Hemin also induced activation of Nrf2, a major transcription factor of HO-1 expression. These responses in MCF-7 cells were completely blocked by pretreatment with brazilin, a HO-1 regulator. These results indicated that brazilin inhibits hemin-induced HO-1 expressions through inactivation of JNK/Nrf2 in MCF-7 cells. Thus, our findings suggest that HO-1 is an important anticancer-target of brazilin in human breast cancer.

Abstract
Three dimeric cassane diterpenoids, caesalpanins A-C, were isolated from the seeds of Caesalpinia sappan L., as well as three known compounds. Their structures were determined via analysis of 1D-, 2D-NMR, and HR-ESI-MS data. Caesalpanins A and B were the second and third compounds that presented a nitrogen-containing cassane diterpenoid dimer linked through one ether bond between C-19 and C-20'. Caesalpanin B exhibited moderate cytotoxic activity against MCF-7 cell lines with IC50 value of 29.98 μm. Caesalpanins A and B had weak inhibitory effects against LPS-induced nitric oxide (NO) production in RAW 264.7 macrophages at 50 μm with inhibitory rate of 36.01 % and 32.93 %, respectively.

Abstract
Vaccinia-related kinase 1 (VRK1), a serine/threonine mitotic kinase, is widely over-expressed in dividing cells and regarded as a cancer drug target primarily due to its function as an early response gene in cell proliferation. However, the mechanism of VRK1 phosphorylation and substrate activation is not well understood. More importantly even the molecular basis of VRK1 interaction with its cofactor, adenosine triphosphate (ATP), is unavailable to-date. As designing specific inhibitors remains to be the major challenge in kinase research, such a molecular understanding will enable us to design ATP-competitive specific inhibitors of VRK1. Here we report the molecular characterization of VRK1 in complex with AMP-PNP, a non-hydrolyzable ATP-analog, using NMR titration followed by the co-crystal structure determined upto 2.07 Å resolution. We also carried out the structural comparison of the AMP-PNP bound-form with its apo and inhibitor-bound counterparts, which has enabled us to present our rationale toward designing VRK1-specific inhibitors.

Abstract
China is a country with a high incidence of gastric cancer (GC), where the GC incidence and the resultant mortality rates account for 50% of those worldwide. Surgical resection remains the primary treatment for GC. However, postoperative patients have a poor prognosis as the majority of patients present with metastases at the time of diagnosis. Therefore, the identification of novel treatment targets is required. The present study aimed to determine the effects of barrier-to-autointegration factor 1 (BANF1) on the clinical features and prognosis of GC, which may aid in discovering a novel tumor diagnostic biomarker and treatment target. The BANF1 gene expression profiles for normal and gastric tumor tissues were downloaded from the Gene Expression Omnibus GSE54129 data set to analyse the expression of BANF1 at the mRNA levels. Then, online survival analysis was performed using the GC database with the Kaplan-Meier Plotter (http://kmplot.com/analysis/) data. To examine the association between BANF1 and clinical features and prognosis, 132 postoperative GC pathological specimens were collected for immunohistochemical analyses. In the GSE54129 data sets, BANF1 expression at the mRNA level was significantly higher in the tumor tissue compared with that in the normal tissue. The same result was obtained in following the immunohistochemical analyses. In addition, BANF1 expression was associated with the patient age, tumor differentiation and infiltration depth. The survival time of BANF1 high-expression patients was shorter compared with that of the low-expression patients, and tumor differentiation status and tumor node metastasis stage were independent prognostic factors of the overall survival of patients with GC. The results of the present study suggest that BANF1 is associated with the clinical features and prognosis of GC. It may be a novel indicator of tumor prognosis and a potential therapeutic target for GC.

Abstract
Vaccinia-related kinase 1 (VRK1) and VRK3 are members of the VRK family of serine/threonine kinases and are principally localized in the nucleus. Despite the crucial roles of VRK1/VRK3 in physiology and disease, the molecular and functional interactions of VRK1/VRK3 are poorly understood. Here, we identified over 200 unreported VRK1/VRK3-interacting candidate proteins by affinity purification and LC-MS/MS. The networks of VRK1 and VRK3 interactomes were found to be associated with important biological processes such as the cell cycle, DNA repair, chromatin assembly, and RNA processing. Interactions of interacting proteins with VRK1/VRK3 were confirmed by biochemical assays. We also found that phosphorylations of XRCC5 were regulated by both VRK1/VRK3, and that of CCNB1 was regulated by VRK3. In liver cancer cells and tissues, VRK1/VRK3 were highly upregulated and its depletion affected cell cycle progression in the different phases. VRK3 seemed to affect S phase progression and G2 or M phase entry and exit, whereas VRK1 affects G1/S transition in the liver cancer, which could be explained by different interacting candidate proteins. Thus, this study not only provides a resource for investigating the unidentified functions of VRK1/VRK3, but also an insight into the regulatory roles of VRK1/VRK3 in biological processes.

Abstract
Many mitotic kinases have been targeted for the development of anti-cancer drugs, and inhibitors of these kinases have been expected to perform well for cancer therapy. Efforts focused on selecting good targets and finding specific drugs to target are especially needed, largely due to the increased frequency of anti-cancer drugs used in the treatment of lung cancer. Vaccinia-related kinase 1 (VRK1) is a master regulator in lung adenocarcinoma and is considered a key molecule in the adaptive pathway, which mainly controls cell survival. We found that ursolic acid (UA) inhibits the catalytic activity of VRK1 via direct binding to the catalytic domain of VRK1. UA weakens surveillance mechanisms by blocking 53BP1 foci formation induced by VRK1 in lung cancer cells, and possesses synergistic anti-cancer effects with DNA damaging drugs. Taken together, UA can be a good anti-cancer agent for targeted therapy or combination therapy with DNA damaging drugs for lung cancer patients.
