Navigating Both Roles: A Photovoice Exploration of the Young Adult Balancing Daughterhood and Caregiving for a Mother With Young-Onset Dementia.

Young adults thrust into the role of caregiving for parents with young-onset dementia (YOD) face unique challenges during their formative years. While existing research acknowledges the crucial role of young adult caregivers, a gap persists in understanding how this group experiences and redefines their identity amidst these circumstances, along with the psychological and societal challenges encountered. This knowledge deficit hinders the identification of suitable social support, adversely affecting the personal growth and well-being of these young adult caregivers. In this single-case study, we used a combination of a semi-structured interview and photovoice to explore the journey of a 19-year-old caregiver, Alice, whose mother had been diagnosed with dementia in the preceding 3 years. Through this unique perspective, we aimed to illuminate how caregiving for a mother with YOD may profoundly redefine familial roles and relationships. Over 3 months, Alice captured significant life moments through photography, selecting meaningful images for bi-weekly meetings. These images served as pivotal themes, triggering in-depth conversations during subsequent interviews to provide nuanced insights into her life experiences. Findings reveal four major themes faced by a young caregiver: (1) challenges adapting to an unexpected role, (2) navigating the complex emotional terrain of losing a loved one to YOD, (3) prioritizing the well-being of the healthy parent, and (4) expressing a profound desire for both informal and formal support. These results underscore the intricate identity and emotional challenges faced by young adult caregivers, emphasizing the urgency of addressing their unique needs through family-centered systemic support services.

Enhanced spontaneous radiation of quantum dots based on modulated anapole states in dielectric metamaterial.

Dielectric nanostructures exhibit low-loss electrical and magnetic resonance, making them ideal for quantum information processing. In this study, the periodic double-groove silicon nanodisk (DGSND) is used to support the anapole state. Based on the distribution properties of the electromagnetic field in anapole states, the anapoles are manipulated by cutting the dielectric metamaterial. Quantum dots (QDs) are used to stimulate the anapole and control the amplification of the photoluminescence signal within the QDs. By opening symmetrical holes in the long axis of the nanodisk in the dielectric metamaterial, the current distribution of Mie resonance can be adjusted. As a result, the toroidal dipole moment is altered, leading to an enhanced electric field (E-field) and Purcell factor. When the dielectric metamaterial is deposited on the Ag substrate separated by the silicon dioxide (SiO2) layer, the structure exhibits ultra-narrow perfect absorption with even higher E-field and Purcell factor enhancement compared to silicon (Si) nanodisks.

Improvement of electrothermal and photothermal properties of ultra-thin graphite film on oxygen plasma-treated polyimide substrate.

Graphene and its derivatives are widely used in the field of energy conversion and management due to their excellent physical and chemical properties. In this paper, ultra-thin graphite film (GF) with thickness of 100-150 nm prepared by chemical vapor deposition was transferred to oxygen plasma-treated polyimide (PI) substrate as flexible heating film. The electrothermal and photothermal properties of GF on PI substrates with different treatment time were studied. The experimental results show that the PI substrate pretreated by oxygen plasma can change the surface morphology of GF, increase its electrical conductivity and light absorption capacity, and significantly improve the electrothermal and photothermal properties of GF heater. Under the low applied voltage of 5 V (power density of 0.81 W cm-2), the surface temperature of GF on 40 min plasma-treated PI substrate can rise to 250 °C, which is nearly 50 °C higher than that of GF on untreated PI substrate. When 100 nm thick commercial multilayer graphene film (MLG) is used, plasma-treated PI substrate can increase the electric heating temperature of MLG by 70 °C. In terms of photothermal performance, the surface temperature of GF on 50 min plasma-treated PI substrate can reach 73 °C under one Sun irradiation, which is 8 °C higher than that on untreated substrate. The experimental results are in good agreement with the simulation research. Our strategy has important implications for the development of efficient and energy-saving graphene/graphite-based heating films for advanced electrothermal and photothermal conversion devices.

Edge enhancement in three-dimensional vortex imaging based on FINCH by Bessel-like spiral phase modulation.

Edge enhancement, as an important part of image processing, has played an essential role in amplitude-contrast and phase-contrast object imaging. The edge enhancement of three-dimensional (3D) vortex imaging has been successfully implemented by Fresnel incoherent correlation holography (FINCH), but the background noise and image contrast effects are still not satisfactory. To solve these issues, the edge enhancement of FINCH by employing Bessel-like spiral phase modulation is proposed and demonstrated. Compared with the conventional spiral phase modulated FINCH, the proposed technique can achieve high-quality edge enhancement 3D vortex imaging with lower background noise, higher contrast and resolution. The significantly improved imaging quality is mainly attributed to the effective sidelobes' suppression in the generated optical vortices with the Bessel-like modulation technique. Experimental results of the small circular aperture, resolution target, and the Drosophila melanogaster verify its excellent imaging performance. Moreover, we also proposed a new method for selective edge enhancement of 3D vortex imaging by breaking the symmetry of the spiral phase in the algorithmic model of isotropic edge enhancement. The reconstructed images of the circular aperture show that the proposed method is able to enhance the edges of the given objects selectively in any desired direction.

mRNA PROTACs: engineering PROTACs for high-efficiency targeted protein degradation.

Proteolysis-targeting chimeras (PROTACs) are essential bifunctional molecules that target proteins of interest (POIs) for degradation by cellular ubiquitination machinery. Despite significant progress made in understanding PROTACs' functions, their therapeutic potential remains largely untapped. As a result of the success of highly flexible, scalable, and low-cost mRNA therapies, as well as the advantages of the first generation of peptide PROTACs (p-PROTACs), we present for the first time an engineering mRNA PROTACs (m-PROTACs) strategy. This design combines von Hippel-Lindau (VHL) recruiting peptide encoding mRNA and POI-binding peptide encoding mRNA to form m-PROTAC and promote cellular POI degradation. We then performed proof-of-concept experiments using two m-PROTACs targeting two cancer-related proteins, estrogen receptor alpha and B-cell lymphoma-extra large protein. Our results demonstrated that m-PROTACs could successfully degrade the POIs in different cell lines and more effectively inhibit cell proliferation than the traditional p-PROTACs. Moreover, the in vivo experiment demonstrated that m-PROTAC led to significant tumor regression in the 4T1 mouse xenograft model. This finding highlights the enormous potential of m-PROTAC as a promising approach for targeted protein degradation therapy.

Interventions for Persons with Young-Onset Dementia and Their Families: A Scoping Review.

Background: Dementia occurring before age 65 is known as young-onset dementia (YOD), with Alzheimer's disease being the most common type. YOD poses unique challenges for persons and families, impacting their working-age years and family responsibilities. Person-centered interventions and services are essential to improve their quality of life and social engagement. Objective: This study aims to synthesize non-pharmacological interventions for persons with YOD and their families to inform future targeted interventions. Methods: We conducted a systematic literature search across four databases: PubMed, PsycINFO, Scopus, and CINAHL. The included articles were carefully screened, categorized, and synthesized by following Arksey and O'Malley's five stages framework. Results: We included 20 studies reported in 24 papers, with 11 studies (14 papers) on persons with YOD and nine studies (10 papers) on families. Quantitative intervention results vary, but qualitative interviews show positive feedback. Stakeholders provided positive evaluations, stating these interventions provided a sense of normalcy, facilitated communication among families, enhanced the independence of persons with YOD, and improved the families' caregiving self-efficacy, thereby reducing care burden and psychological distress. The heterogeneity among the studies posed integration challenges. Conclusions: Interventions for YOD can improve the quality of life for both persons with YOD and their families. More extensive intervention studies are urgently needed, especially in developing countries, with a focus on family-centered and life course perspectives. In future intervention research design, a more extensive incorporation of stakeholder involvement is essential for successful implementation. Moreover, the integration of new technologies shows promise as a potential avenue for intervention advancement.

Lived experiences of maintaining self-identity among persons living with young-onset dementia: A qualitative meta-synthesis.

BACKGROUND: The self-identity of persons with young-onset dementia (YOD) is affected by the disease progression. However, the lived experience of maintaining self-identity along the disease trajectory is understudied. This meta-synthesis integrated qualitative data on the challenges, coping strategies, and needs of persons living with YOD and how their experiences affected their self-identity over time. METHODS: Four English (PubMed, Scopus, CINAHL, PsycINFO) and two Chinese (CNKI and Wanfang) electronic databases were searched for published literature peer-reviewed from the time of database inception to 2022. We used thematic analysis to extract and synthesize data from the literature concerning the long-term lived experiences of persons living with YOD. RESULTS: A total of five peer-reviewed publications were eligible for inclusion in this meta-synthesis study. We identified four themes: (1) declining cognitive function and a prolonged diagnostic process threaten the self-identity of persons living with YOD, (2) struggling to accept the diagnosis of YOD and maintain self-identity, (3) maintaining self-identity and the normalcy of life through social support and person-centered care, and (4) living with YOD through self-development and self-identity reshaping at a later stage of the disease. CONCLUSIONS: Persons living with YOD experience challenges maintaining their self-identity throughout the disease trajectory. These challenges are affected by their cognitive function, experiences of personal and social stigma associated with the disease, perceived social support, and person-centered care. Study findings have implications for developing tailored supportive programs for persons living with YOD at various stages of the disease trajectory.

Metal deposits associated with brain atrophy in the deep gray matter nucleus in Wilson's disease.

Regional atrophy and metal deposition are typical manifestations in Wilson's disease, but their relationship has not been systematically investigated. We aim to investigate the association of regional brain atrophy and metal deposition in the deep gray matter nucleus at MRI in Wilson's disease. We acquired the structural and susceptibility mapping and performed a cross-sectional comparison of volume and susceptibility in deep gray matter nucleus. The most extensive and severe atrophy was detected in brain regions in neuro-Wilson's disease, as well as the most widespread and heaviest metal deposits. Metal deposits were significantly negatively correlated with volume in the bilateral thalamus, caudate, and putamen. None of correlation was found between the clinical score with volume or susceptibility in the focused regions. In the 1-year follow-up analysis, the volume of right thalamus, globus pallidus, and brainstem and the susceptibility of the left caudate have decreased significantly as the symptom improvement. In Wilson's disease, phenotypes have varied scope and extend of volumetric atrophy and metal deposits. This study is expected to take the lead in revealing that in neuro-Wilson's disease, greater regional atrophy associated with heavier metal deposits in Wilson's disease. Moreover, after 1-year treatment, the imaging data have changed as the patient's condition improvement.

Quercetin Alleviates Acrylamide-Induced Liver Injury by Inhibiting Autophagy-Dependent Ferroptosis.

Acrylamide (ACR) generated in carbohydrate-rich foods during thermal processing has been demonstrated to exhibit hepatotoxicity. As one of the most consumed flavonoids with diet, quercetin (QCT) possesses the ability to protect against ACR-induced toxicity, albeit its mechanism is unclear. Herein, we discovered that QCT alleviated ACR-induced elevated levels of reactive oxygen species (ROS), AST, and ALT in mice. RNA-seq analysis revealed that QCT reversed the ferroptosis signaling pathway upregulated by ACR. Subsequently, experiments indicated that QCT inhibited ACR-induced ferroptosis through the reduction of oxidative stress. With autophagy inhibitor chloroquine, we further confirmed that QCT suppressed ACR-induced ferroptosis by inhibiting oxidative stress-driven autophagy. Additionally, QCT specifically reacted with autophagic cargo receptor NCOA4, blocked the degradation of iron storage protein FTH1, and eventually downregulated the intracellular iron levels and the consequent ferroptosis. Collectively, our results presented a unique approach to alleviate ACR-induced liver injury by targeting ferroptosis with QCT.

Translation and psychometric testing of the sense of competence in Dementia Care Staff Scale in Chinese amongst dementia care staff in nursing homes of China.

BACKGROUND: Although China has the largest population of persons with dementia, there is no validated tool available to accurately assess formal caregivers' competence in dementia care in long-term care settings. Appropriately assessing nursing staff's level of competence in dementia care is the first step to develop precision training interventions to improve the quality of dementia care. The Sense of Competence in Dementia Care Staff scale (SCIDS) is a user-friendly tool with satisfactory reliability and validity. We adapted SCIDS into a Chinese version (SCIDS-C) and validated its uses in China's socio-cultural context to assess nursing staff's capability and competence in dementia care at nursing homes. AIMS: We aimed to adapt and psychometrically test the tool among frontline nursing staff in long-term care settings in China. METHODS: The research employed a correlational design with repeated measures. In translation section, we adapted and tailored the original scale in the cultural and social context in China's nursing homes. The scale's adaptation consists of translating adaptation and semantic equivalence. In psychometric testing phase, we tested the validity and reliability of the scale with 174 nursing staff conveniently from six nursing homes. Construct validity was tested using exploratory factor analysis (EFA), including principal component analysis and maximum variance rotation method. Reliability was tested using Cronbach's alpha value and intraclass correlation coefficient (ICC). RESULTS: The SCIDS-C has 17 items, which belong to the two sub-scales, the Relationship-Centered Care(RCC) and Professional Care(PC). The Cronbach's alpha value was 0.88, showing a good internal consistency. The full scale's value of ICC was 0.94 which indicated good reliability. Exploratory factor analysis(EFA) extracted 2 common factors in each sub-scale, cumulative variance contribution rate was 56.71% and 53.92%, respectively. The named four factors are the same as the Sense of Competence in Dementia Care Staff (SCIDS) scale in English, including Building Relationships, Sustaining Personhood, Professionalism and Care Challenges. CONCLUSION: The SCIDS-C has shown good reliability and validity. It can be used as an appropriate tool to evaluate the competence of nursing care staff to provide dementia care for residents in nursing homes.

Based on quality, energy consumption selecting optimal drying methods of mango slices and kinetics modelling.

Mangoes have a short shelf life because of their high-water content. This study aimed to compare the effect of three drying methods (HAD, FIRD and VFD) on mango slices to improve product quality and reduce costs. Mangoes were dried at various temperatures (50, 60, 70 °C) with different slice thicknesses (3, 5, 7, 10 mm). Results indicated that FIRD was the most cost-effective with the dried mango containing the highest sugar-acid ratio, and when the mango slices thickness was 7 mm and drying at 70 °C, the ascorbic acid content, rehydration ratio, sugar-acid ratio, and energy consumption per unit volume reached 56.84 ± 2.38 mg/100 g, 2.41 ± 0.05, 83.87 ± 2.14, and 0.53 kWh/L. Among three mathematical models, the Page model described the most satisfactory drying behaviour of mango slices in FIRD. This study provides useful information in mango processing industry and FIRD is supposed to be a promising drying method.

Polysaccharides from natural Cordyceps sinensis attenuated dextran sodium sulfate-induced colitis in C57BL/6J mice.

As potential candidates for treating ulcerative colitis (UC), polysaccharides have been attracting extensive interest in recent years. Cordyceps sinensis (C. sinensis) is a kind of traditional Chinese edible food, and its polysaccharide fractions have been found to be effective in regulating immunity and protecting the kidneys. To determine the potential function of polysaccharides from natural C. sinensis on UC, their effects in terms of histological, serological, biochemical, and immunological aspects on dextran sulphate sodium (DSS)-induced colitis mice model were investigated. Results showed that the polysaccharides significantly alleviated colitis by increasing the colon length, alleviating colon tissue damage, and inhibiting the activation of the NF-κB pathway. In addition, polysaccharides reduced the contents of tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß) in the serum, increased the number of goblet cells, and improved the expression of intestinal tight junction proteins (Occludin and Claudin-1). They also evidently enhanced the formation of IgA-secretory cells and sIgA contents. Furthermore, the polysaccharides modulated the gut microbiota by decreasing the relative abundance of Bilophila and increasing the relative abundance of Dehalobacterium, Coprococcus, Oscillospira, and Desulfovibrio, which is accompanied by an increase in the short chain fatty acids' (SCFAs) concentrations in cecal contents. These results suggested that C. sinensis polysaccharides possessed promising intervening effects on experimental acute UC in mice.

MALDI mass spectrometry in food carbohydrates analysis: A review of recent researches.

Carbohydrates, including monosaccharides, oligosaccharides and polysaccharides, are widely distributed in food resources. Matrix-assisted laser desorption/ionization (MALDI), a soft ionization technique, is extensively applied in carbohydrates analysis. MALDI mass spectrometers are capable to generate spectra rapidly and record mass profiles or fingerprints from foods, usually with simple sample preparation or pretreatment. Therefore, this review described recent research progress on MALDI mass spectrometry (MS) detection in food carbohydrates, especially for the improvement of ionization efficiency and their application in structure characterization of polysaccharides from food and edible herbs. Furthermore, the quantitative study and mass spectrometry imaging were also briefly summarized.

Abrocitinib 100 mg versus 200 mg for atopic dermatitis: a meta-analysis of randomized controlled trials.

Introduction: It is elusive to compare the efficacy and safety of abrocitinib 100 mg versus 200 mg once daily in patients with atopic dermatitis. Aim: This meta-analysis aims to explore the influence of abrocitinib 100 mg versus 200 mg on the treatment of atopic dermatitis. Material and methods: Several databases including PubMed, EMbase, Web of science, EBSCO, and Cochrane library were systematically searched through July 2021. We included randomized controlled trials (RCTs) assessing the effect of abrocitinib 100 mg versus 200 mg for patients with atopic dermatitis. Results: Four RCTs were included in the meta-analysis. Compared with abrocitinib 100 mg for atopic dermatitis, abrocitinib 200 mg had a remarkably positive impact on IGA response (OR = 1.78; 95% CI: 1.39-2.28; p < 0.00001), EASI-75 (OR = 2.03; 95% CI: 1.60-2.57; p < 0.00001), NRS response (OR = 1.97; 95% CI: 1.27-3.08; p = 0.003), and adverse events (OR = 1.43; 95% CI: 1.11-1.84; p = 0.005), but it showed no obvious influence on serious adverse events (OR = 0.59; 95% CI: 0.25-1.37; p = 0.22). Conclusions: Abrocitinib 200 mg is better than abrocitinib 100 mg for the treatment of atopic dermatitis.

Plasmon mode manipulation based on multi-layer hyperbolic metamaterials.

Metamaterial with hyperbolic dispersion properties can effectively manipulate plasmonic resonances. Here, we designed a hyperbolic metamaterial (HMM) substrate with a near-zero dielectric constant in the near-infrared region to manipulate the plasmon resonance of the nano-antenna (NA). For NA arrays, tuning the equivalent permittivity of HMM substrate by modifying the thickness of Au/diamond, the wavelength range of plasmon resonance can be manipulated. When the size of the NA changes within a certain range, the spectral position of the plasmon resonance will be fixed in a narrow band close to the epsilon-near-zero (ENZ) wavelength and produce a phenomenon similar to "pinning effect." In addition, since the volume plasmon polaritons (VPP) mode is excited, it will couple with the localized surface plasmon (LSP) mode to generate a spectrum splitting. Therefore, the plasmon resonance is significantly affected and can be precisely controlled by designing the HMM substrate.

Structural characteristic of pectin-glucuronoxylan complex from Dolichos lablab L. hull.

Polysaccharides are important constituents in Dolichos lablab hull. Herein, pectin-glucuronoxylan complex from D. lablab hull designated as DLHP-3 (D. lablab hull polysaccharide,) was prepared by ion exchange and gel permeation chromatography, and further characterized by acid degradation and enzymatic hydrolysis, methylation combined with GC-MS, NMR and MALDI-TOF-MS analysis. Both of pectin and glucuronoxylan regions were found in DLHP-3. The glucuronoxylan region consisted of a →4)-ß-Xylp-(1→ backbone with branches of α-GlcpA-(1→ substituted at O-2 site, and the ratio of xylose to glucuronic acid was about 5:1. Acetyl groups were mainly attached to O-3 site of →2,4)-ß-Xylp-(1→ residues. The main chain of pectin region could be represented by →4)-α-GalpA-(1→4)-α-GalpA-(1→ and →2)-α-Rhap-(1→4)-α-GalpA-(1→ with partial methyl-esterification. The side chains were deduced to embrace arabinan and arabinogalactan linked to rhamnogalacturonan-I region. Pectin was probably covalently bound to glucuronoxylan. Our findings uncovered the molecular structure of pectin-glucuronoxylan complex from D. lablab hull.

Humanistic Nursing Care for Patients in Low-Resourced Clinical Settings from Students' Perspectives: A Participatory Qualitative Study.

INTRODUCTION: It is of utmost importance to understand how we can better prepare students to value humanistic spirits and provide humanistic care, a core element of quality care for patients/family characterized by empathy and holistic care, from school to clinical settings (practicum) in low-resourced healthcare environments with seriously low nursing staffing levels. The current study explored participants' experiences of learning and delivering humanistic care for patients. METHODOLOGY: This is a participatory qualitative study. Eligible participants are undergraduate students who completed all the core curricula and are ready to start their one-year clinical practicum/internships. A total of 120 eligible undergraduate students were included in the study. Participants were encouraged to share their own thoughts, questions, and perspectives on learning and providing humanistic care in clinical settings during their one-year practicum from 2020 to 2021. RESULTS: Three major themes emerged: 1. From Textbook to Providing Humanistic Care in low-resourced work contexts; 2. Ethical Considerations; and 3. Implications for Humanistic Nursing Care Education. DISCUSSION: Systematic reforms are needed to make clinical settings more humanistic care-friendly for nurses and nursing students. It is significant to help students internalize the essence of humanistic care in low-resource settings.

Food for the elderly based on sensory perception: A review.

Background: The impairments of physiological functions caused by aging are common problems in the elderly, especially the impairments of sensory perception. Besides, close relationship between food sensory perception and nutritional status also suggests the importance of dietary management for the elderly population. The foods taking sensory perception into account are urgently needed by the elderly. Scope and approach: This review analyzed sensory perception changes and their effects on food behaviors and nutritional status. Besides, sensory properties essential for aged-foods and acquisition methods, as well as current status of such foods were summarized. Key findings and conclusions: Soft, smooth and moisty foods were more suitable for the elderly with chewing and swallowing dysfunction, which can be prepared by gelation, enzyme treatment, blade tenderization and other non-thermal technologies. Flavor enhancement/enrichment, irritant addition and packet sauces were recommended to compensate the impairment of chemical sensory. Molds, piping bag and 3D printing were suggested for refining appearance of pureed foods, and improving appetite of the elderly.

Effects of steam on polysaccharides from Polygonatum cyrtonema based on saccharide mapping analysis and pharmacological activity assays.

BACKGROUND: Polygonatum cyrtonema, one of origins of Polygonata Rhizoma (HuangJing in Chinese), is traditionally steamed repeatedly before being used as herbal medicine in China. However, there has no standard for steaming of HuangJing. Therefore, a comprehensive study for effects of steam on polysaccharides from Polygonatum cyrtonema based on saccharide mapping, a powerful method developed for polysaccharides analysis, and pharmacological activity are still necessary, which is helpful to explore the effect of steam on the physiochemical and biological activities of its polysaccharides and develop steaming standard of Polygonatum cyrtonema. METHODS: To explore the effect of steam on physiochemical and biological activities of P. cyrtonema polysaccharides (PCP), six polysaccharides named PCP0, PCP1, PCP2, PCP3, PCP4 and PCP5 were extracted from the herb consecutively steamed for 0-5 times, respectively. Their molecular weight distribution, monosaccharide composition and PACE fingerprints were investigated through HPSEC-MALLS-RID, HPAEC-PAD and saccharide mapping based on polysaccharides analysis by using carbohydrate gel electrophoresis (PACE) and HPTLC, respectively. In addition, their antioxidant ability and immunostimulatory activities on RAW 264.7 cells in terms of NO production and phagocytosis were compared. RESULTS: Results suggested that molecular weights could be changed during steam, which increased by first steaming and then decreased with further steaming though all polysaccharides' molecular weights were 105-107 Da. They all showed irregularly spherical conformation in aqueous solution based on AFM imaging. Their monosaccharide composition and PACE fingerprints were significantly different after steaming, i.e., galactose increased while glucose and mannose decreased, and ß-1,4-Galp appeared while ß-1,4-Manp increased, after steaming. Steamed PCP significantly increased scavenging activity against ABTS radicals, while PCP0 had the best immunostimulatory effect on RAW 264.7 in terms of NO production and phagocytosis. CONCLUSIONS: In summary, steam significantly affected the chemical composition and bioactivities of polysaccharides from P. cyrtonema. Considering the balance beneficial effects of steaming on antioxidant and immunopotentiation activities of PCP, 2 times of continuous steam is the optimal choice under the given conditions.

Aloe gel glucomannan induced colon cancer cell death via mitochondrial damage-driven PINK1/Parkin mitophagy pathway.

Mitophagy can selectively remove damaged mitochondria, which is critical in regulating mitochondrial homeostasis in diseases, such as cancer. Herein, we found that Aloe gel glucomannan (AGP) significantly inhibited the proliferation of colon cancer cells. RNA-seq analysis revealed that AGP upregulated autophagy, lysosome and mitochondrial fission signal pathways in colon cancer cell line CT26. Notably, AGP induced the accumulation of impaired and reactive oxygen species (ROS)-generating mitochondria, which triggered excessive mitophagy. Interestingly, the mitophagy activator enhanced AGP-induced mitophagy and cytotoxicity, whereas the mitophagy inhibitor reversed the influence of AGP. Furthermore, activation of PINK1/Parkin mitophagy pathway and transcription factor EB (TFEB) signaling was dependent on ROS overproduction. Taken together, these results indicated that AGP induced cytotoxic mitophagy through ROS-related PINK1/Parkin pathway and TFEB activation in CT26 cells. The research would provide theoretical basis for the development of AGP as a promising anticancer agent.
