Comparative genomics reveals putative copper tolerance genes in a Fusarium oxysporum strain.

Copper has been widely used as a main component in fungicides due to its versatility and effectivity. However, copper contamination from the environment creates selective pressure for the emergence of copper-tolerant pathogenic fungal strains that may proliferate and further cause damage to important agricultural crops. Although some studies focused on specific cellular mechanisms of copper tolerance, comprehensive genomic data are lacking.

Endometriosis as a highly relevant yet neglected gynecologic condition in Asian women.

Endometriosis is a chronic, debilitating disease characterized by the growth of endometrial tissues outside the endometrium. Its prevalence seems to differ across ethnicities, with the disease affecting and presenting with advanced stages in Asians more than any other race. Despite this, data on endometriosis in Asians is limited, and there seems to be a lack of support for endometriosis research in Asia.

Bisphenol S Increases Cell Number and Stimulates Migration of Endometrial Epithelial Cells.

Objective: To determine whether bisphenol S (BPS), a common substitute for bisphenol A (BPA), induces cell proliferation and migration in human endometrial epithelial cells (Ishikawa) and adult mouse uterine tissues.

Methodology: Human endometrial Ishikawa cells were exposed to low doses of BPS (1 nM and 100 nM) for 72 hours. Cell proliferation was assessed through the viability assays MTT and CellTiter-Glo.

Cellular Senescence, a Novel Area of Investigation for Metastatic Diseases.

Metastasis is a systemic condition and the major challenge among cancer types, as it can lead to multiorgan vulnerability. Recently, attention has been drawn to cellular senescence, a complex stress response condition, as a factor implicated in metastatic dissemination and outgrowth. Here, we examine the current knowledge of the features required for cells to invade and colonize secondary organs and how senescent cells can contribute to this process.

Lactobacillus delbrueckii reduces anxiety-like behavior in zebrafish through a gut microbiome - brain crosstalk.

Certain bacteria possess the ability to reduce anxiety- and stress-related behaviors through the gut microbiome-brain axis. Such bacteria are called psychobiotics, and can be used to improve mood and cognition. However, only a few bacteria have been characterized as psychobiotics, and their exact mechanism of action remains unclear.

Diaporthe/Phomopsis longicolla degrades an array of bisphenol analogues with secreted laccase.

With recent initiatives to ban bisphenol A (BPA) in certain commercial products, manufacturers shifted to the production and use of BPA analogues. However, some of these BPA alternatives still possess endocrine disruptive activities. Many fungal enzymes are known to biodegrade phenolic compounds, such as BPA.

The role of cellular senescence in female reproductive aging and the potential for senotherapeutic interventions.

Background: Advanced maternal age is associated with decreased oocyte quantity and quality as well as uterine and placental dysfunctions. These changes lead to infertility, pregnancy complications and birth defects in the offspring. As the mean age of giving birth is increasing worldwide, prevention of age-associated infertility and pregnancy complications, along with the more frequent use of ART, become extremely important.

The senescence-associated secretory phenotype: Fueling a wound that never heals.

Wound healing is impaired with advanced age and certain chronic conditions, such as diabetes and obesity. Moreover, common cancer treatments, including chemotherapy and radiation, can cause unintended tissue damage and impair wound healing. Available wound care treatments are not always effective, as some wounds fail to heal or recur after treatment.

Elevated levels of perfluoroalkyl substances in breast cancer patients within the Greater Manila Area.

Several studies have reported exposure of humans to various endocrine disrupting chemicals (EDCs) worldwide. However, there is a lack of data regarding EDC exposures in humans living in Southeast Asian countries, such as the Philippines. Hence, this study measured levels of 41 EDCs in women residing in the Greater Manila Area, home to the second largest city in Southeast Asia.

Transcriptome analysis reveals involvement of oxidative stress response in a copper-tolerant Fusarium oxysporum strain.

High amount of copper is toxic to most organisms, but endophytic fungi can develop survival strategies to tolerate and respond to environmental stressors such as heavy metal contaminants. While high copper induces oxidative stress, it is still unclear which genes are associated with copper tolerance. Here, we performed a metatranscriptome analysis of endophytic fungi isolated from a black nightshade plant Solanum nigrum L.

Per- and polyfluoroalkyl substances (PFAS) as contaminants of emerging concern in Asia's freshwater resources.

The occurrence of per- and polyfluoroalkyl substances (PFAS) in water resources is an emerging concern because of their environmental persistence and bioaccumulation in humans. In Western countries, health advisories regarding PFAS exposure have been released to warn the public of its potential adverse effects. However, awareness regarding PFAS exposure in Asia is still at its infancy as reflected by the minimal safeguards imposed to protect the population from exposure.

Metformin regulation of progesterone receptor isoform-B expression in human endometrial cancer cells is glucose-dependent.

Metformin (MET) constitutes the first-line treatment against type 2 diabetes. Growing evidence linking insulin resistance and cancer risk has expanded the therapeutic potential of MET to several cancer types. However, the oncostatic mechanisms of MET are not well understood.

Alangium longiflorum Merr. Leaf Extract Induces Apoptosis in A549 Lung Cancer Cells with Minimal NFκB Transcriptional Activation.

Unlabelled: The chemotherapy drug doxorubicin (DOX) is effective in treating many types of cancers. However, due to its pro-inflammatory and cardiotoxic side effects, other remedies have also been explored as alternative treatments. The plant Alangium longiflorum was reported to contain cytotoxic activity against cancer cells, but it is unclear whether this plant would also yield side effects similar to doxorubicin.

Cellular Senescence Promotes Skin Carcinogenesis through p38MAPK and p44/42MAPK Signaling.

Cellular senescence entails an irreversible growth arrest that evolved in part to prevent cancer. Paradoxically, senescent cells secrete proinflammatory and growth-stimulatory molecules, termed the senescence-associated secretory phenotype (SASP), which is correlated with cancer cell proliferation in culture and xenograft models. However, at what tumor stage and how senescence and the SASP act on endogenous tumor growth is unknown.

A Pilot Cancer-Phenome Biobanking System in a Low-Resource Southeast Asian Setting: The Philippine General Hospital Biobank Experience.

Biobanking has become an indispensable tool for translational research and health innovations. While the field of biobanking has progressed and evolved globally, biobanking in developing Association of Southeast Asian Nations (ASEAN) countries such as the Philippines remains underrepresented because of several challenges often encountered in these low- and middle-income countries. Recently, the Philippine government has undertaken enormous efforts to advancing research and development in the country, and one of the current research pursuits is the establishment of biobanks, with the hope of attaining more discoveries and innovations in the future.

Synergistic Cytotoxicity of Renieramycin M and Doxorubicin in MCF-7 Breast Cancer Cells.

Renieramycin M (RM) is a KCN-stabilized tetrahydroisoquinoline purified from the blue sponge sp., with nanomolar ICs against several cancer cell lines. Our goal is to evaluate its combination effects with doxorubicin (DOX) in estrogen receptor positive MCF-7 breast cancer cells.

A novel rapamycin analog is highly selective for mTORC1 in vivo.

Rapamycin, an inhibitor of mechanistic Target Of Rapamycin Complex 1 (mTORC1), extends lifespan and shows strong potential for the treatment of age-related diseases. However, rapamycin exerts metabolic and immunological side effects mediated by off-target inhibition of a second mTOR-containing complex, mTOR complex 2. Here, we report the identification of DL001, a FKBP12-dependent rapamycin analog 40x more selective for mTORC1 than rapamycin.

Exposure to Aeromonas hydrophila induces inflammation and increases expression of the gene encoding for a putative dual CTLD-containing lectin in milkfish liver.

Milkfish (Chanos chanos Forsskal) is an important aquaculture product and is the sole extant species of the family Chanidae (order Gonorynchiformes). While there are already several reports regarding milkfish aquaculture, studies on milkfish immunity and gene expression are very limited. In this study, we showed that Aeromonas hydrophila induces inflammation in milkfish liver.

Epidermal Barrier Protects against Age-Associated Systemic Inflammation.

Skin provides barrier protection for the body, but aging disrupts epidermal barrier function. Hu et al. show that disruption of the epidermal barrier increases serum cytokine levels partly because of increased cytokine production by the skin.

The female reproduction and senescence nexus.

Successful pregnancy is regulated by several soluble factors that are differentially expressed throughout gestation. These factors are important to initiate and establish embryo implantation and parturition. Senescent cells, which undergo permanent cell proliferation arrest in response to stress, also produce several secreted factors, referred to as the senescence-associated secretory phenotype (SASP).

Positive and negative effects of cellular senescence during female reproductive aging and pregnancy.

Cellular senescence is a phenomenon occurring when cells are no longer able to divide even after treatment with growth stimuli. Because senescent cells are typically associated with aging and age-related diseases, cellular senescence is hypothesized to contribute to the age-related decline in reproductive function. However, some data suggest that senescent cells may also be important for normal physiological functions during pregnancy.

Targeting Senescent Cells: Possible Implications for Delaying Skin Aging: A Mini-Review.

Senescent cells are induced by a wide variety of stimuli. They accumulate in several tissues during aging, including the skin. Senescent cells secrete proinflammatory cytokines, chemokines, growth factors, and proteases, a phenomenon called senescence-associated secretory phenotype (SASP), which are thought to contribute to the functional decline of the skin as a consequence of aging.

Placental membrane aging and HMGB1 signaling associated with human parturition.

Aging is associated with the onset of several diseases in various organ systems; however, different tissues may age differently, rendering some of them dysfunctional sooner than others. Placental membranes (fetal amniochorionic membranes) protect the fetus throughout pregnancy, but their longevity is limited to the duration of pregnancy. The age-associated dysfunction of these membranes is postulated to trigger parturition.

Mitochondrial Dysfunction Induces Senescence with a Distinct Secretory Phenotype.

Cellular senescence permanently arrests cell proliferation, often accompanied by a multi-faceted senescence-associated secretory phenotype (SASP). Loss of mitochondrial function can drive age-related declines in the function of many post-mitotic tissues, but little is known about how mitochondrial dysfunction affects mitotic tissues. We show here that several manipulations that compromise mitochondrial function in proliferating human cells induce a senescence growth arrest with a modified SASP that lacks the IL-1-dependent inflammatory arm.

Pleiotropic age-dependent effects of mitochondrial dysfunction on epidermal stem cells.

Tissue homeostasis declines with age partly because stem/progenitor cells fail to self-renew or differentiate. Because mitochondrial damage can accelerate aging, we tested the hypothesis that mitochondrial dysfunction impairs stem cell renewal or function. We developed a mouse model, Tg(KRT14-cre/Esr1) (20Efu/J) × Sod2 (tm1Smel) , that generates mitochondrial oxidative stress in keratin 14-expressing epidermal stem/progenitor cells in a temporally controlled manner owing to deletion of Sod2, a nuclear gene that encodes the mitochondrial antioxidant enzyme superoxide dismutase 2 (Sod2).
