Abstract
In several cases of mitochondrial diseases, the underlying genetic and bioenergetic causes of reduced oxidative phosphorylation (OxPhos) in mitochondrial dysfunction are well understood. However, there is still limited knowledge about the specific cellular outcomes and factors involved for each gene and mutation, which contributes to the lack of effective treatments for these disorders. This study focused on fibroblasts from a patient with Autosomal Dominant Optic Atrophy (ADOA) plus syndrome harboring a mutation in the Optic Atrophy 1 (OPA1) gene. By combining functional and transcriptomic approaches, we investigated the mitochondrial function and identified cellular phenotypes associated with the disease. Our findings revealed that fibroblasts with the OPA1 mutation exhibited a disrupted mitochondrial network and function, leading to altered mitochondrial dynamics and reduced autophagic response. Additionally, we observed a premature senescence phenotype in these cells, suggesting a previously unexplored role of the OPA1 gene in inducing senescence in ADOA plus patients. This study provides novel insights into the mechanisms underlying mitochondrial dysfunction in ADOA plus and highlights the potential importance of senescence in disease progression.

Abstract
A normal somatic cell undergoes cycles of finite cellular divisions. The presence of surveillance checkpoints arrests cell division in response to stress inducers: oxidative stress from excess free radicals, oncogene-induced abnormalities, genotoxic stress, and telomere attrition. When facing such stress when undergoing these damages, there is a brief pause in the cell cycle to enable repair mechanisms. Also, the nature of stress determines whether the cell goes for repair or permanent arrest. As the cells experience transient or permanent stress, they subsequently choose the quiescence or senescence stage, respectively. Quiescence is an essential stage that allows the arrested/damaged cells to go through appropriate repair mechanisms and then revert to the mainstream cell cycle. However, senescent cells are irreversible and accumulate with age, resulting in inflammation and various age-related disorders. In this review, we focus on senescence-associated pathways and therapeutics understanding cellular senescence as a cascade that leads to aging, while discussing the recent details on the molecular pathways involved in regulating senescence and the benefits of therapeutic strategies against accumulated senescent cells and their secretions.

Abstract
Aging is a natural phenomenon characterized by accumulation of cellular damage and debris. Oxidative stress, cellular senescence, sustained inflammation, and DNA damage are the main cellular processes characteristic of aging associated with morphological and functional decline. These effects tend to be more pronounced in tissues with high metabolic rates such as the brain, mainly in regions such as the prefrontal cortex, hippocampus, and amygdala. These regions are highly related to cognitive behavior, and therefore their atrophy usually leads to decline in processes such as memory and learning. These cognitive declines can occur in physiological aging and are exacerbated in pathological aging. In this article, we review the cellular processes that underlie the triggers of aging and how they relate to one another, causing the atrophy of nerve tissue that is typical of aging. The main topic of this review to determine the central factor that triggers all the cellular processes that lead to cellular aging and discriminate between normal and pathological aging. Finally, we review how the use of supplements with antioxidant and anti-inflammatory properties reduces the cognitive decline typical of aging, which reinforces the hypothesis of oxidative stress and cellular damage as contributors of physiological atrophy of aging. Moreover, cumulative evidence suggests their possible use as therapies, which improve the aging population's quality of life.

[PMID: 35723499 DOI: 10.1093/treephys/tpac064] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 06/07/2022] [Indexed: 06/15/2023]
Abstract
The Moso bamboo (Phyllostachys edulis) leaf copes well with cold winters in southeastern China. However, until now, there has been almost no research on its adaptation mechanisms to cold weather. Herein, we found that the Moso bamboo leaf has evolved several anatomical structures that may play a role in enhancing its cold tolerance. These structures include fewer fusiform cells, smaller bulliform cells, lower stomata density and many more trichomes, as well as lower relative water content than in the leaf of a cold-sensitive bamboo species, Bambusa ventricosa. Untargeted metabolomic analysis revealed that the winter leaf of Moso bamboo had 10- to 1000-fold higher stress-resistant metabolites such as glutathione, trehalose and ascorbic acid than the leaf of B. ventricosa on both warm and cold days. In contrast to the leaves that grew on a warm day, some metabolites such as glutathione and trehalose increased dramatically in the leaves of Moso bamboo that grew on a cold day. However, they unexpectedly decreased in the leaf of B. ventricosa growing at cold temperatures. Transcriptome analysis revealed a cold stress response network that includes trehalose, glutathione, flavonoid metabolism, DNA repair, reactive oxygen species degradation, stress-associated genes and abiotic stress-related plant hormones such as jasmonic acid, abscisic acid and ethylene. The potential mediator transcription factors, such as EREBP, HSF, MYB, NAC and WRYK, were also significantly upregulated in Moso bamboo leaves growing at cold temperatures. Interestingly, many newly identified genes were involved in the transcriptome of the winter leaf of the Moso bamboo. Most of these new genes have not even been annotated yet. The above results indicate that the Moso bamboo leaf has evolved special histological structures, metabolic pathways and a cold stress-tolerant transcriptome to adapt to the cold weather in its distribution areas.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Skin diseases are among the most common human health affections. A healthy skin promotes a healthy body that can be achieved through modern, allopathic and natural medicines. Therefore, medicinal plants can be a reliable therapy in treating skin diseases in humans through a diverse range of bioactive molecules they contain. AIM OF THE STUDY This review aims to provide for the first-time scientific evidence related to the dermatological properties of Morocco's medicinal plants and it aims to provide a baseline for the discovery of new drugs having activities against skin issues. METHODS This review involved an investigation with different search engines for Moroccan ethnobotanical surveys published between 1991 and 2021. The plants used to treat skin diseases have been determined. Information regarding pharmacological effects, phytochemical, and clinical trials related to the plants listed in this review was collected from different scientific databases like PubMed, Science Direct, Google Scholar, Web of Science and Scopus. The data were analyzed and summarized in the review. RESULTS A total of 401 plants belonging to 86 families mainly represented by Asteraceae, Lamiaceae, Fabaceae, and Apiaceae which have been documented to be in common use by Moroccans for managing skin diseases. Among those plants recorded, the most commonly used are Allium cepa L, Chamaeleon gummifer (L.) Cass and Salvia rosmarinus Schleid. Mill. Leaves were the most commonly used plant part, while powder and decoction were the most common method of traditional drug preparation. 107 of the 401 plants (27%) have undergone pharmacological validation. A total of 44 compounds isolated from 27 plants were investigated to treat different types of skin diseases, and 25 plants have been clinically studied for their activities against skin diseases. CONCLUSION The beneficial effects of using Moroccan medicinal plants to treat skin diseases, according to traditional practices, have been proven in numerous scientific studies. Therefore, other studies should focus on isolating and identifying specific bioactive compounds from plant extracts, revealing more valuable therapeutic properties. Furthermore, additional reliable clinical trials are needed to confirm their beneficial effect on patients with skin diseases.

Abstract
Senescence is the phenomenon by which physiological functions of organisms degenerate with time. Cellular senescence is marked by an inhibition of cell cycle progression. Beta-galactosidase accumulates in the lysosomes of aged cells. In this study, human dermal fibroblast cells (HDFs) were treated with 0.5 μM doxorubicin for 4 h to induce cellular senescence. Senescence-associated beta-galactosidase (SA-β-gal) activity was then measured 72 h after treatment with aerial parts of Dendranthema zawadskii var. lucidum (Nakai) J.H. Park (DZ) extract. Treatment with DZ extract significantly decreased SA-β-gal activity in a dose-dependent manner in HDFs. Additionally, DZ extract treatment reduced age-related oxidative stress and inflammation in the aortas of aged rats. The reactive oxygen species (ROS) levels in aortas of aged control rats were higher than those in young rats. However, DZ extract-fed aged rats showed significantly lower ROS levels than the aged control rats. When the aged rats were treated with DZ extract at either 0.2 or 1.0 mg∙kg−1∙day−1, NF-κB levels in aorta tissue decreased significantly compared to those in aorta tissue of the aged control rats without DZ treatment. In addition, DZ extract-fed aged rat aortas showed significant reductions in expression of iNOS and COX-2 induced by NF-κB translocation. Therefore, these results suggest that DZ effectively inhibited senescence-related NF-κB activation and inflammation. DZ extract may have a role in the prevention of the vascular inflammatory responses that occur during vascular aging.

Abstract
The biological process of renal aging is characterized by progressive structural and functional deterioration of the kidney leading to end-stage renal disease, requiring renal replacement therapy. Since the discovery of pivotal mechanisms of senescence such as cell cycle arrest, apoptosis inhibition, and the development of a senescence-associated secretory phenotype (SASP), efforts in the understanding of how senescent cells participate in renal physiological and pathological aging have grown exponentially. This has been encouraged by both preclinical studies in animal models with senescent cell clearance or genetic depletion as well as due to evidence coming from the clinical oncologic experience. This review considers the molecular mechanism and pathways that trigger premature renal aging from mitochondrial dysfunction, epigenetic modifications to autophagy, DNA damage repair (DDR), and the involvement of extracellular vesicles. We also discuss the different pharmaceutical approaches to selectively target senescent cells (namely, senolytics) or the development of systemic SASP (called senomorphics) in basic models of CKD and clinical trials. Finally, an overview will be provided on the potential opportunities for their use in renal transplantation during ex vivo machine perfusion to improve the quality of the graft.

Abstract
Arthritis is characterized by irreversible joint destruction and presents a global health burden. Natural alternatives to synthetic drugs have been gaining popularity for their safety and effectiveness. Juglanin has demonstrated a range of anti-inflammatory effects in various tissues and cell types. However, the pharmacological function of Juglanin in arthritis and chondrocytes has been little studied. ATDC5 cells were treated with 1 μg/mL lipopolysaccharide (LPS) in the presence or absence of juglanin (2.5, 5 μM) for 24 h. The effects of juglanin on cellular nucleotide-binding domain leucin-rich repeat receptor 3 (NLRP3) inflammasome complex and endproduct interleukin 1β (IL-1β) and interleukin (IL-18) were assessed by reverse transcription-polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), and Western blot experiments. The oxidative stress was measured by super oxide dismutase (SOD) activity and NADPH oxidase 4 (NOX4) expression. The dependent effect of juglanin on silent information regulator 2 homolog 1 (SIRT1) was evaluated by siRNA knockdown approach. Juglanin significantly reduced cellular oxidative stress by downregulating NOX4 expression production and rescuing the decreased activity of total SOD induced by LPS. Juglanin inhibited the activation of the TxNIP/NLRP3/ASC/caspase-1 axis, and decreased production of IL-1β and IL-18. Moreover, juglanin rescued the LPS-induced decrease in SIRT1 expression. SIRT1 silencing abolished the anti-NLRP3 inflammasome effect of juglanin, indicating that the effects of juglanin are dependent on its amelioration on SIRT1 expression. Juglanin possesses an anti-inflammatory and anti-ROS capacity in chondrocytes, and this study provides available evidence that juglanin may be of use in the treatment of arthritis.

Abstract
Extensive solar ultraviolet B (UVB) exposure of the skin results in inflammation and oxidative stress, which may contribute to skin cancer. Natural products have attracted attention for their role in the effective treatment of cutaneous neoplasia. Juglanin is purified from the crude extract of Polygonum aviculare, exhibiting anti-oxidant, anti-inflammatory and anti-cancer activities. Jugalanin was used in the current study to investigate whether it may ameliorate UVB irradiation-induced skin damage by reducing oxidative stress and suppressing the inflammatory response in vivo and in vitro. In the present study, hairless mice were exposed to UVB irradiation in the absence or presence of juglanin administration for 10 weeks. The findings indicated that juglanin inhibited UVB-induced hyperplasia and decreased infiltration in the skin of mice. UVB exposure-induced oxidative stress in mice and cells was inhibited by juglanin via enhancing anti-oxidant activity. Additionally, juglanin markedly reduced pro-inflammatory cytokine release, including cyclic oxidase 2, interleukin-1β and tumor necrosis factor-α, triggered by chronic UVB irradiation. Juglanin-ameliorated skin damage was associated with its suppression of mitogen activated protein kinases (MAPKs), including p38, extracellular signal regulated 1/2, and c-Jun N-terminal kinases, as well as nuclear factor (NF)-κB signaling pathways, which was dependent on nuclear factor-E2-related factor 2 (Nrf2)-modulated reactive oxygen species generation. Taken together, these data indicate that juglanin protected against UVB-triggered oxidative stress and inflammatory responses by suppressing MAPK and NF-κB activation via enhancing Nrf2 activity.

Abstract
Meiguihua oral solution (MOS), a classical Chinese medicinal formula, was approved by the China Food and Drug Administration for production. However, the quality evaluation of MOS has not been reported. In this present study, qualitative and quantitative analysis of MOS were conducted by ultra high performance liquid chromatography coupled to quadrupole-orbitrap high resolution mass spectrometry (UHPLC-Q-orbitrap-HRMS) and high performance liquid chromatography-tri-quadrupole linear ion trap mass spectrometry (HPLC-tri-Q-LIT-MS). Totally 46 phenolic compounds (21 flavonoids and 25 tannins) were identified in the MOS, among them 14 polyphenols were not reported in raw plant materials of MOS. The simultaneous quantification of ten compounds including gallic acid, quercetin-3-O-sophoroside, ellagic acid, sophoraflavonoloside, hyperoside, isoquercitrin, avicularin, astragalin, quercitrin and juglanin, which were completed in 16 min in the negative electrospray ionization (ESI) mode under multiple reaction monitoring (MRM) method. Linearity was reached fine determination coefficient (r2 > 0.9995). Precisions, repeatability, stability (inter-day and intra-day), and recovery were validated and the relative standard deviations (RSD) were less than 2.9%, 4.7%, 3.6% and 1.79%, respectively. This result proved the high sensitivity and efficiency of the method. The quantitative and qualitative analysis of MOS would provide the substantial basis for further quality control and medicinal values.

Abstract
Hereditary renal cystic diseases are characterized by defects in primary cilia of renal tubular epithelial cells and abnormality of tubular epithelium, which ultimately result in the development of renal cysts. However, the mechanism leading from abnormality of the tubular epithelium to cystogenesis is not well understood. In this report, we demonstrate a critical role for Robo2 in regulating epithelial development, including ciliogenesis, polarization, and differentiation. We found that Robo2 deficiency results in cystic kidneys, and the cyst cells showed defective cilia and polarity defects in tubular epithelium. The cyst cells, less than terminally differentiated, continue to proliferate. We further established that Robo2 works with p53 as well as polarity and ciliary proteins (Par3, PKCς, ZO-2, and Claudin-2) to regulate these processes. Robo2 binds to Baiap2 (also known as IRSp53) through the IRSp53/MIM homology domain in renal epithelial cells. This binding allows Robo2 to phosphorylate MDM2 at Ser166 via Baiap2 and maintain p53 homeostasis. Disruption of the Robo2-Baiap2 complex causes MDM2 to be subjected to dephosphorylation, leading to a high level of active p53, and initiated p53-mediated cellular senescence via p21 and decreased the expression of ZO-1, ZO-2, PKCς, Par3, and Claudin-2 proteins, resulting in defects in epithelial development, including ciliogenesis, polarization, and differentiation. Importantly, double knockout of Robo2 and p53 rescued all the epithelial defects in kidneys compared with those in Robo2-knockout kidneys. Taken together, the present results demonstrate that Robo2 deficiency causes renal cystic disease, which is largely dependent on defective Robo2-Baiap2 integrated signaling in kidneys.

Abstract
Cellular senescence (CS) is one of hallmarks of aging and accumulation of senescent cells (SCs) with age contributes to tissue or organismal aging, as well as the pathophysiologies of diverse age-related diseases (ARDs). Genetic ablation of SCs in tissues lengthened health span and reduced the risk of age-related pathologies in a mouse model, suggesting a direct link between SCs, longevity, and ARDs. Therefore, senotherapeutics, medicines targeting SCs, might be an emerging strategy for the extension of health span, and prevention or treatment of ARDs. Senotherapeutics are classified as senolytics which kills SCs selectively; senomorphics which modulate functions and morphology of SCs to those of young cells, or delays the progression of young cells to SCs in tissues; and immune-system mediators of the clearance of SCs. Some senolytics and senomorphics have been proven to markedly prevent or treat ARDs in animal models. This review will present the current status of the development of senotherapeutics, in relation to aging itself and ARDs. Finally, future directions and opportunities for senotherapeutics use will discussed. This knowledge will provide information that can be used to develop novel senotherapeutics for health span and ARDs. [BMB Reports 2019; 52(1): 47-55].

Abstract
Even if cancer represents a burden for human society, an exhaustive cure has not been discovered yet. Low therapeutic index and resistance to pharmacotherapy are two of the major limits of antitumour treatments. Natural products represent an excellent library of bioactive molecules. Thus, tapping into the natural world may prove useful in identifying new therapeutic options with favourable pharmaco-toxicological profiles. Juglans regia, or common walnut, is a very resilient tree that has inhabited our planet for thousands of years. Many studies correlate walnut consumption to beneficial effects towards several chronic diseases, such as cancer, mainly due to the bioactive molecules stored in different parts of the plant. Among others, polyphenols, quinones, proteins, and essential fatty acids contribute to its pharmacologic activity. The present review aims to offer a comprehensive perspective about the antitumour potential of the most promising compounds stored in this plant, such as juglanin, juglone, and the ellagitannin-metabolites urolithins or deriving from walnut dietary intake. All molecules and a chronic intake of the fruit provide tangible anticancer effects. However, the scarcity of studies on humans does not allow results to be conclusive.

Abstract
Ultraviolet (UV) radiation induces skin injury, and is associated with the development and formation of melanoma, which is a highly lethal form of skin cancer. Juglanin is a natural product, which is predominantly extracted from Polygonum aviculare, and is considered a functional component among its various compounds. Juglanin has been reported to exert marked protective effects in various diseases via the inhibition of inflammation and tumor cell growth. The present study aimed to explore the effects of juglanin on human skin cancer induced by UV and to reveal the underlying molecular mechanism. In the present study, immunohistochemical analysis, western blot analysis, RT-qPCR analysis and flow cytometry assays were mainly used in vivo and/or in vitro. The results indicated that in mice, UVB exposure increased susceptibility to carcinogens, and accelerated disease pathogenesis. Conversely, juglanin was able to ameliorate this condition via inhibition of inflammation, suppression of cell proliferation and induction of apoptosis via p38/c‑Jun N‑terminal kinase (JNK) blockage, nuclear factor (NF)‑κB inactivation and caspase stimulation in vivo. In addition, in vitro, the present study demonstrated that treatment of UVB‑stimulated B16F10 melanoma cells with juglanin resulted in a dose‑dependent decrease in cell viability, as well as increased apoptosis via the upregulation of caspase expression and poly (ADP‑ribose) polymerase cleavage. In addition, juglanin markedly attenuated p38/JNK signaling, inactivated the phosphoinositide 3‑kinase/protein kinase B pathway and suppressed UVB‑induced NF‑κB activation. Taken together, these results indicated the possibility of applying juglanin in combination with UVB as a potential therapeutic strategy for preventing skin cancer.

Abstract
Acute lung injury in children is a complication showing devastating disorders linked to fibrosis progression and inflammation response. Fibrosis and inflammation response are two markers for acute lung injury. Juglanin is a natural product mainly isolated from green walnut husks of Juglans mandshurica, which isconsidered as the functional composition among a series of compounds. It exhibited effective role in various diseases by inhibiting inflammation response. In our study, the protective effects and anti-inflammatory activity of juglanin were investigated in mice and lung cells treated by lipopolysaccharide (LPS) to reveal the possible mechanism by which juglanin attenuates acute lung injury. The mice were separated into four groups. The mouse model was established with 15 mg/kg LPS injection. Juglanin dramatically reduced the inflammation of cell infiltration. Compared to mice only treated with LPS, LPS-treated mice in the presence of juglanin developed less lung fibrosis with lower levels of α-smooth muscle-actin (α-SMA), collagen type I, collagen type III, and transforming growth factor-β1 (TGF-β1). Additionally, juglanin markedly downregulated inflammatory cytokine secretion and phosphorylated nuclear factor-κB (NF-κB) expression via inhibiting IKKα/IκBα signaling pathway. Our results indicate that juglanin has a protective role in LPS-triggered acute lung injury via suppression of fibrosis and inflammation response by NF-κB signaling pathways inactivation. Thus, juglanin may be a potential candidate as dietary supplement for acute lung injury for children in future.

Abstract
Parkinson's disease (PD) is a common neuro-degenerative disorder, and novel therapeutic targets are required for the treatment of PD. Juglanin is a natural compound extracted from the crude Polygonum aviculare, exhibiting anti-inflammatory, anti-oxidant and anti-cancer activities. In our study, PD in mice was induced by systemic LPS treatment as evidenced by enhanced α-synuclein and reduced tyrosine hydroxylase (TH), which were reversed by juglanin treatment. Moreover, juglanin administration attenuated LPS-caused behavioral and memory impairments and reduced LPS-induced enhancement of neuro-degenerative markers, including amyloid β (Aβ) and p-Tau. Additionally, juglanin ameliorated synaptic functionality through promoting the expression of synaptic markers, such as SYP, PSD-95 and SNAP-25. Toll-like receptor 4 (TLR4) signaling in brain regulates neuroinflammation, contributing to neurodegenerative diseases. Furthermore, LPS induced neuroinflammation through the acceleration of various pro-inflammatory cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-18 (IL-18) and Cyclooxygenase-2 (COX-2), via activating TLR4/nuclear factor (NF)-κB pathway in hippocampus of mice and microglia cells. Juglanin significantly reduced LPS-induced production of pro-inflammatory cytokines and blocked TLR4/NF-κB pathway. We also found that LPS-induced astrocytes (AST) activity was prevented by juglanin through down-regulating glial fibrillary acidic protein (GFAP) and Iba1 in vivo and in vitro. Together, our results indicated that juglanin ameliorated neuroinflammation-related memory impairment, and neurodegeneration through impeding TLR4/NF-κB, indicating its potential for PD prevention.

Abstract
The study of cellular senescence and proliferative lifespan is becoming increasingly important because of the promises of autologous cell therapy, the need for model systems for tissue disease and the implication of senescent cell phenotypes in organismal disease states such as sarcopenia, diabetes and various cancers, among others. Here, we explain the concepts of proliferative cellular lifespan and cellular senescence, and we present factors that have been shown to mediate cellular lifespan positively or negatively. We review much recent literature and present potential molecular mechanisms by which lifespan mediation occurs, drawing from the fields of telomere biology, metabolism, NAD(+) and sirtuin biology, growth factor signaling and oxygen and antioxidants. We conclude that cellular lifespan and senescence are complex concepts that are governed by multiple independent and interdependent pathways, and that greater understanding of these pathways, their interactions and their convergence upon specific cellular phenotypes may lead to viable therapies for tissue regeneration and treatment of age-related pathologies, which are caused by or exacerbated by senescent cells in vivo.

Abstract
Juglanin (Jug) is obtained from the crude extract of Polygonum aviculare, exerting suppressive activity against cancer cell progression in vitro and in vivo. Juglanin administration causes apoptosis and reactive oxygen species (ROS) in different types of cells through regulating various signaling pathways. In our study, the effects of juglanin on non-small cell lung cancer were investigated. A significant role of juglanin in suppressing lung cancer growth was observed. Juglanin promoted apoptosis in lung cancer cells through increasing Caspase-3 and poly ADP-ribose polymerase (PARP) cleavage, which is regulated by TNF-related apoptosis-inducing ligand/Death receptors (TRAIL/DRs) relied on p53 activation. Anti-apoptotic members Bcl-2 and Bcl-xl were reduced, and pro-apoptotic members Bax and Bad were enhanced in cells and animals receiving juglanin. Additionally, nuclear factor-κB (NF-κB), phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) and mitogen-activated protein kinases (MAPKs) activation were inhibited by juglanin. Further, juglanin improved ROS and induced autophagy. ROS inhibitor N-acetyl-l-cysteine (NAC) reversed apoptosis induced by juglanin in cancer cells. The formation of autophagic vacoules and LC3/autophagy gene7 (ATG7)/Beclin1 (ATG6) over-expression were observed in juglanin-treated cells. Also, juglanin administration to mouse xenograft models inhibited lung cancer progression. Our study demonstrated that juglanin could be a promising candidate against human lung cancer progression.

Abstract
Cellular senescence, a state of irreversible growth arrest and altered cell function, causes aging-related diseases. Hence, treatment modalities that could target aging cells would provide a robust therapeutic avenue. Herein, for the first time, we utilized CD9 receptors (overexpressed in senescent cells) for nanoparticle targeting in addition to the inherent β-galactosidase activity. In our study, CD9 monoclonal antibody-conjugated lactose-wrapped calcium carbonate nanoparticles loaded with rapamycin (CD9-Lac/CaCO3/Rapa) were prepared for targeted rapamycin delivery to senescent cells. The nanoparticles exhibited an appropriate particle size (~130 nm) with high drug-loading capacity (~20%). In vitro drug release was enhanced in the presence of β-galactosidase suggesting potential cargo drug delivery to the senescent cells. Furthermore, CD9-Lac/CaCO3/Rapa exhibited high uptake and anti-senescence effects (reduced β-galactosidase and p53/p21/CD9/cyclin D1 expression, reduced population doubling time, enhanced cell proliferation and migration, and prevention of cell cycle arrest) in old human dermal fibroblasts. Importantly, CD9-Lac/CaCO3/Rapa significantly improved the proliferation capability of old cells as suggested by BrdU staining along with significant reductions in senescence-associated secretory phenotypes (IL-6 and IL-1β) (P < 0.05). Altogether, our findings suggest the potential applicability of CD9-Lac/CaCO3/Rapa in targeted treatment of senescence.

Abstract
High fructose-feeding is an essential causative factor leading to the development and progression of hepatitis associated with high levels of endotoxin (LPS). Juglanin, as a natural compound extracted from the crude Polygonum aviculare, displayed inhibitory activity against inflammation response and cancer growth. However, researches about its role on anti-inflammation and apoptosis are far from available. Here, it is the first time that juglanin was administrated to investigate whether it inhibits fructose-feeding-induced hepatitis in rats and to elucidate the possible mechanism by which juglanin might recover it. Fructose-feeding rats were orally administrated with juglanin of 5, 10 and 20mg/kg for 6 weeks, respectively. Juglanin exerted prevention of fructose-feeding-stimulated increased LPS levels, accelerated alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) and up-regulated inflammatory cytokines expression in serum, mainly including tumor necrosis factor-alpha (TNF-a), Interleukin 1beta (IL-1β), Interleukin 6 (IL-6) and Interleukin 18 (IL-18). Meanwhile, toll-like receptor 4 (TLR4)-modulated mitogen-activated protein kinase (MAPK)/nuclear factor kappa B (NF-κB) and apoptosis-related Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway are involved in the progression of hepatic injury and inflammation. And juglanin was found to suppress fructose-feeding-induced activation of these signaling pathways compared with the model group administrated only with fructose. These results indicate that juglanin represses inflammatory response and apoptosis via TLR4-regulated MAPK/NF-κB and JAK2/STAT3 signaling pathway respectively in rats with hepatitis induced by LPS for fructose-feeding. Treatment of juglanin might be an effective therapeutic strategy for preventing hepatitis.

Abstract
Cellular senescence contributes to tissue and organismal aging, tumor suppression and progress, tissue repair and regeneration, and age-related diseases. Thus, aging intervention might be beneficial for treatment and prevention of diverse age-related diseases. In the present study, we investigated whether four compounds purified from Inula japonica exert inhibitory activity against cellular senescence induced by adriamycin in human umbilical vein endothelial cells (HUVECs). Among them, compound 4 (quercetagetin 3,4'-dimethyl ether) showed inhibitory activity against cellular senescence, which was confirmed by senescence-associated β-galactosidase (SA-β-gal) activity, p53 and p21 protein levels, and intracellular ROS levels. Compound 4 also reduced SA-β-gal activity in HUVECs under replicative senescence. These results suggest that compound 4 represses cellular senescence in HUVECs and might be useful for the development of dietary supplements or cosmetics that alleviate tissue aging or age-related diseases.

Abstract
Hericium erinaceum is an edible and medicinal mushroom widely used in Korea, Japan, and China. On the search for biologically active compounds supporting the medicinal usage, the MeOH extract of the fruiting bodies of H. erinaceum was investigated for its chemical constituents. Six compounds were isolated and identified as hericenone D (1), (22E,24R)-5α,8α-epidioxyergosta-6,22-dien-3β-ol (2), erinacerin B (3), hericenone E (4), hericenone F (5) and isohericerin (6) by comparing their spectroscopic data with previously reported values. The inhibitory effects on adriamycin-induced cellular senescence in human dermal fibroblasts (HDFs) and human umbilical vein endothelial cells (HUVECs) of the isolates (1-6) were studied. Among the isolated compounds, ergosterol peroxide (2) reduced senescence associated β-galactosidase (SA-β-gal) activity increased in HUVECs treated with adriamycin. According to experimental data obtained, the active compound may inspire the development of a new pharmacologically useful substance to be used in the treatment and prevention of age-related diseases.
