Cardiac microvascular endothelial cells (CMECs) dysfunction is an important pathophysiological event in the cardiovascular complications induced by diabetes. However, the underlying mechanism is not fully clarified. Autophagy is involved in programmed cell death. Here we investigated the potential role of autophagy on the CMECs injury induced by high glucose. CMECs were cultured in normal or high glucose medium for 6, 12 and 24 h respectively. The autophagy of CMECs was measured by green fluorescence protein (GFP)-LC3 plasmid transfection...

Human umbilical cord mesenchymal stem cells (hUC-MSCs) are potential stromal cells which are regarded as the most feasible stem cell group in cell therapy. The maintenance of cell survival without differentiation is important in cell transplantation and stem cell therapy. However, negative factors exist in cell transplantation. Lysophosphatidic acid (LPA) is a non-antigenic small molecule phospholipid which induced several fundamental cellular responses, such as cell proliferation, apoptosis and migration. In this study we aimed to explore the effects of LPA on the survival and differentiation of MSCs and its availability in cell therapy...

A decrease in flow cytometric forward light scatter (FSC) is commonly interpreted as a sign of apoptotic cell volume decrease (AVD). However, the intensity of light scattering depends not only on the cell size but also on its other characteristics, such as hydration, which may affect the scattering in the opposite way. That makes estimation of AVD by FSC problematic. Here, we aimed to clarify the relationship between light scattering, cell hydration (assayed by buoyant density) and cell size by the Coulter technique...

Platinum containing drugs are widely used to treat advanced lung carcinomas. However, their clinical success is still limited due to severe side effects, and drug resistance. Alternative approaches are warranted to augment efficacy of platinum based chemotherapeutic drugs with minimal side effects. Intricatinol (INT), a homoisoflavonoid, has been shown to possess anti-tubercular, antioxidant, hypoglycaemic, and hypolipidemic activity. However, its anticancer activity largely remains unknown. In the present study, we have evaluated anticancer potential of INT alone or in combination with cisplatin (CIS) in non-small cell lung carcinoma (A549) cells...

SIRT1, a member of the sirtuin family, has recently emerged as a vital molecule in controlling ovarian function. The aims of the present study were to investigate SIRT1 expression and analyze SIRT1-mediated apoptosis in human granulosa cells (GCs). Human ovarian tissues were subjected to immunohistochemistry for localization of SIRT1 expression. SIRT1 knockdown in a human ovarian GC tumor line (COV434) was achieved by small interfering RNA, and the relationship between apoptosis and SIRT1 was assessed by quantitative reverse transcription polymerase chain reaction and western blotting...

Inflammasomes are intracellular multiprotein complexes of the innate immune system. Upon an inflammatory insult, such as infection or intracellular damage, a nucleotide-binding oligomerization domain-like receptor (NLR) sensor protein and the adaptor protein ASC (apoptosis-associated speck-like protein containing a caspase activation and recruitment domain) are assembled to activate protease procaspase-1. This protease processes pro-IL-1β and pro-IL-18 cytokines, which are released to induce the inflammatory response...

Resveratrol (RES) is a natural polyphenol having anti-proliferative activity against breast cancer cells. RES in combination with other chemo modulatory agents, minimizes toxicity and increases efficacy of the treatment. Salinomycin (SAL), a monocarboxylic polyether ionophore is known for selectively targeting breast cancer stem cells. Purpose of the present study was to investigate whether RES in combination with SAL exerts synergistic anti-proliferative activity on breast cancer cells. We further evaluated the molecular mechanism behind SAL and RES mediated cell death...

To fight cancer at its roots by targeting cancer stem cells is a promising approach for therapy. Previously, an indolylquinoline derivative, 3-((7-ethyl-1H-indol-3-yl)-methyl)-2-methylquinoline (EMMQ), was reported effectively inhibiting the growth of lung cancer cells through impairment of cellular mitochondria functions. To address more on drug efficiency, the study further exploited if EMMQ can impede the propagation of tumorspheres stemmed from non-small cell lung cancer cells. EMMQ inhibited proliferation of spheroids in culture...

Hyperthermia induced by heat stress (HS) is known to inhibit proliferation and induce cell death in cancer. We previously demonstrated that checkpoint kinase 1 (Chk1) contributes to G2/M arrest and cell survival under HS; however, the role of Chk2, a functional analog of Chk1, in regulation of the cell cycle and cell death under HS is still unknown. Here, we addressed the role of Chk2 using Molt-4 cells with p53-targeted shRNA (Molt-4/shp53) and parental control cells (Molt-4/V). Chk2 inhibition suppressed C-terminal acetylation of p53 and delayed the induction of p53-target genes in Molt-4/V cells under HS; however, Chk2 inhibition failed to inhibit apoptosis induced by HS, indicating that Chk2 was dispensable for p53-dependent apoptosis under HS...

Death receptor 5 (DR5) is an important target for development of anticancer agents against triple-negative breast cancer (TNBC). Recently, we reported the molecular level details for the modulation of TRAIL-DR5 axis by quinacrine (QC) in breast cancer cells. In this work, the DR5 mediated anticancer potential of topoisomerase inhibitor etoposide (ET) and doxorubicin (DOX) against TNBC has been evaluated. ET and DOX enhanced the DR5 expression in TNBC cells, whereas non-topoisomerase inhibitors pifithrin-α (PIF) and dexamethasone (DEX) failed to do so...

Treatment of leishmaniasis involves the use of antimonials, miltefosine, amphotericin B or pentamidine. However, the side effects of these drugs and the reports of drug-resistant parasites demonstrate the need for new treatments that are safer and more efficacious. Histone deacetylase inhibitors are a new class of compounds with potential to treat leishmaniasis. Herein, we evaluated the effects of KH-TFMDI, a novel histone deacetylase inhibitor, on Leishmania amazonensis promastigotes and intracellular amastigotes...

Curcumin, a dietary supplement or herbal medicine from Curcuma longa, has shown antitumor activity in different cancer cell lines and clinical trials. CA916798, a novel protein, is overexpressed in multidrug-resistant tumor cells. This study aimed to assess the effects of curcumin on regulating chemosensitivity in cisplatin-resistant non-small cell lung cancer (NSCLC) cells in vitro and to explore the underlying molecular mechanisms. Human cisplatin-sensitive A549 and cisplatin-resistant A549/CDDP lung adenocarcinoma cells were treated with curcumin to assess cell viability and gene modulations using quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blotting...

Transglutaminase 2 (TG2) is a multi-functional protein that has both protein cross-linking and guanosine 5'-triphosphate (GTP) hydrolysis activities. The activities of this protein are controlled by many cellular factors, including calcium (Ca(2+)) and GTP, and have been implicated in several physiological activities, including apoptosis, angiogenesis, wound healing, cellular differentiation, neuronal regeneration, and bone development. TG2 is linked to many human diseases such as inflammatory disease, celiac disease, neurodegenerative disease, diabetes, tissue fibrosis, and various cancers and is one of the most dynamic enzymes in terms of its functions, structures, and regulatory mechanisms...

The hyperplastic growth of rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLSs) and inflammatory response are pathological hallmarks of RA. It has been reported that Astragalus polysaccharides (APS) possess appreciable anti-inflammatory activity against adjuvant-induced arthritis. Nevertheless, little is known about the role and detailed mechanism underlying the therapeutic effects of APS in RA. This study demonstrated that administration of APS dose-dependently impaired cell viability, increased cell apoptosis by decreasing Bcl-2 expression, increasing Bax expression and Caspase3 activity in IL-1β-stimulated RSC-364 cells and RA-FLS...

Anoikis is a programmed cell death induced upon cell detachment from extracellular matrix. Anoikis resistance is a critical mechanism in tumor metastasis. Cancer cells deregulate and adapt their metabolism to survive in the absence of adhesion, spreading metastases to distant organs. These adaptations include abnormal regulation of growth factor receptors activating prosurvival signaling pathways, such as the Ras/ERK and PI3K/Akt pathways, and extracellular matrix remodeling, leading to metastasis by an increase of invasiveness and inhibiting anoikis...

Kaposi's sarcoma associated herpes virus (KSHV) infected primary effusion lymphoma (PEL) is a rare aggressive form of non-Hodgkin's lymphoma of B cells. KSHV latent and lytic antigens modulate several host cellular signalling pathways especially mammalian target of rapamycin (mTOR), STAT-3 and nuclear factor-kappa B (NF-κB) for rapid tumor progression and immune evasion. Current chemotherapeutic strategies are becoming ineffective as they kill only dividing cells and inefficient to target molecular pathways crucial for active virus replication and its survival...

The neurodegeneration of cerebellar granule cells, after low potassium induced apoptosis, is known to be temporally divided into an early and a late phase. Voltage-dependent anion channel-1 (VDAC1) protein, changing from the closed inactive state to the active open state, is central to the switch between the early and late phase. It is also known that: (i) VDAC1 can undergo phosphorylation events and (ii) AMP-activated protein kinase (AMPK), the sensor of cellular stress, may have a role in neuronal homeostasis...
