Lactate dehydrogenase (LDH) is being increasingly recognized as a major factor in the progression of breast cancer. It was previously shown that short interfering RNA‑mediated knockdown of either LDH‑A or ‑B isoform resulted in inhibition of cell motility due to reduced lactate levels in the extracellular environment. The aim of the present study was to determine the use of pharmacological LDH inhibitors to reduce aggressive behavior of breast cancer cells. The effect of LDH inhibitors was investigated in both estrogen receptor (ER)+ and ER‑ breast cancer cell lines and in normal breast epithelial cells...

Pulmonary hypertension (PH) is a progressive lethal disease, which is characterized by abnormal vascular remodeling and persistently elevated pulmonary artery pressure, eventually leading to right heart failure and even death. Although great progress has been made in treating PH, the mortality rate remains high. Metabolic disorders are one of the important hallmarks of PH. Obesity, lipids, glucose tolerance and insulin resistance are risk factors for numerous cardiovascular diseases and are often accompanied by a considerable increase in serum uric acid (SUA) concentrations...

Breast cancer is the most common malignancy in women. Metastatic breast cancer is incurable and is a major cause of shortened patient survival. The different molecular types of breast cancer make targeted therapy difficult and a complex challenge. Aryl hydrocarbon receptor (AhR) is an evolutionarily conserved transcription factor that has been implicated in the metabolism of xenobiotic ligands. AhR is activated by numerous exogenous and endogenous ligands and participates in multiple physiological processes, including proliferation, migration, invasion and apoptosis...

Lung adenocarcinoma (LUAD) is one of the deadliest cancers regarding both mortality rate and number of deaths and warrants greater effort in the development of potential therapeutic targets. The enhancer of rudimentary homolog ( ERH ) has been implicated in the promotion and progression of certain types of cancer. In the present study, ERH was assessed for its expression pattern and survival association with LUAD in public transcriptomic and proteomic databases. Bioinformatic methods and data from websites, including University of Alabama at Birmingham CANcer data analysis Portal and The Cancer Genome Atlas, were utilized to demonstrate the functional behaviors and corresponding pathways of ERH in LUAD...

Perinatal exposure of the neonatal lung to inflammation leads to decreased lung angiogenesis and the development of bronchopulmonary dysplasia (BPD). Notably, autologous cord blood mononuclear cells (ACBMNCs) can substantially prevent severe BPD and decrease the inflammatory response in surviving very preterm neonates. Angiopoietin‑like protein 7 (Angptl7) is one of the main paracrine cytokines in cord blood stem cells, and is capable of stimulating human hematopoietic stem and progenitor cell expansion...

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the control data in Fig. 2B and C on p. 7332, showing immunofluorescence and migration assay experiments respectively, were strikingly similar to data appearing in different form in another article which was written by different authors at different research institutes [Tian L, Shen D, Li X, Shan X, Wang X, Yan Q and Liu J: Ginsenoside Rg3 inhibits epithelial‑mesenchymal transition (EMT) and invasion of lung cancer by down‑regulating FUT4...

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the GAPDH control western blotting data shown in Fig. 4A were strikingly similar to data appearing in different form in another article written by different authors at different research institutes. Owing to the fact that the contentious data in the above article had already been published prior to its submission to Molecular Medicine Reports , the Editor has decided that this paper should be retracted from the Journal...

Lipopolysaccharide‑induced (LPS) neuroinflammation serves an important role in the development of depression. Monocyte chemotactic protein‑1‑induced protein 1 (MCPIP1, also known as ZC3H12A and Regnase‑1) possesses endoribonuclease and deubiquitinase activities. In the present study, the effects of MCPIP1 on LPS‑induced depression were assessed. A mouse model of hippocampal neuroinflammation was established by intraperitoneal injection of LPS. Microglia were treated with LPS, MCPIP1 overexpression vector, MCPIP1 knockdown vector or TLR4 inhibitor...

Cerebrovascular diseases (CVDs) have become a global public health problem and ischemia‑reperfusion injury, the major cause of neurological impairment exacerbation, is closely related to excitotoxicity. The present study aimed to investigate the effects of changes in heat shock protein (HSP)90β expression and verify whether HSP90β regulates EAAT2 expression in a cerebral ischemia‑reperfusion injury model. Healthy adult Sprague‑Dawley (SD) male rats were used to establish a control group, sham‑operated group, middle cerebral artery occlusion (MCAO) group, empty virus group and lentivirus group...

The heat shock cognate 71 kDa protein (Hsc70) is a stress‑inducible ATPase that can protect cells against harmful stimuli. Transient receptor potential vanilloid 1 (TRPV1) is a well‑documented nociceptor. Notably, Hsc70 can inhibit TRPV1 expression and function, suggesting that Hsc70 may have pain regulation potential. However, the role of Hsc70 in stress‑induced hyperalgesia remains unclear. In the present study, the participation of Hsc70 and its regulator microRNA (miR)‑3120 were investigated in forced swim (FS) stress‑induced mechanical hyperalgesia in rats in an inflammatory state...

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the VEGF western blotting data shown in Fig. 4A on p. 3392 were strikingly similar to data appearing in different form in other articles written by different authors at different research institutes.  Owing to the fact that the contentious data in the above article had already been published elsewhere prior to its submission to Molecular Medicine Reports , the Editor has decided that this paper should be retracted from the Journal...

Atherosclerosis (AS) is a chronic inflammatory disease characterized by increased oxidative injury in vascular endothelial cells. Inhibiting the oxidative damage of vascular endothelial cells can effectively prevent the occurrence and development of AS. Of note, Genistein (GEN; ID no. 5280961) is phytochemical found in legume family which has flavonoid properties with multiple potential biological activities including antioxidant, anti‑inflammatory and anticancer. Antioxidant capacity of GEN has a potential protective effect on vascular endothelial cells after oxidative stress...

Ferroptosis is driven by iron‑dependent accumulation of lipid hydroperoxides, and hemolytic hyperbilirubinemia causes accumulation of unconjugated bilirubin and iron. The present study aimed to assess the role of ferroptosis in hemolytic hyperbilirubinemia‑induced brain damage (HHIBD). Rats were randomly divided into the control, phenylhydrazine (PHZ) and deferoxamine (DFO) + PHZ groups, with 12 rats in each group. Ferroptosis‑associated biochemical and protein indicators were measured in the brain tissue of rats...

Insulin growth factor‑1 (IGF‑1) is an endocrine regulator that plays an important role in normal growth and development. IGF‑1 mediated effects may result in protecting macrophages from immunometabolic response. However, it is unclear whether IGF‑1 has a protective effect on fatty acid‑induced macrophages damage. In the present study, THP‑1 cells were differentiated into macrophages and stimulated with palmitic acid (PA) in the absence or presence of IGF‑1. Macrophages apoptosis was measured by Cell Counting Kit‑8 assay, flow cytometry, Hoechst 33342 staining and western blotting...

Subacute progressive neuropsychiatric symptoms with cognitive and motor impairment and autoimmune seizures are some of the typical symptoms of anti‑N‑methyl‑D‑aspartate receptor (anti‑NMDAR) encephalitis. The mechanisms underlying this disease are yet to be elucidated, which could be partly attributed to the lack of appropriate animal models. The present study aimed to establish an active immune mouse model of anti‑NMDAR encephalitis. Mice were immunized with the extracellular segment of the NMDA1 protein, then subjected to open‑field and novel object recognition experiments...

Telomeres are major contributors to cell fate and aging through their involvement in cell cycle arrest and senescence. The accelerated attrition of telomeres is associated with aging‑related diseases, and agents able to maintain telomere length (TL) through telomerase activation may serve as potential treatment strategies. The aim of the present study was to assess the potency of a novel telomerase activator on TL and telomerase activity in vivo . The administration of a nutraceutical formulation containing Centella asiatica extract, vitamin C, zinc and vitamin D3 in 18‑month‑old rats for a period of 3 months reduced the telomere shortening rate at the lower supplement dose and increased mean the TL at the higher dose, compared to pre‑treatment levels...

Abnormal activation of microglia and the production of proinflammatory cytokines can lead to chronic neuroinflammation, which is an important pathological characteristic of Parkinson's disease (PD). Neferine is a chemical compound extracted from lotus seed which has previously been reported to exert protective effects on the development of several types of cancer, myocardial injury and hypoxic‑ischemic encephalopathy. However, its effect on microglial functions in neuroinflammation remains to be clarified...

Intraoperative radiotherapy (IORT) is a precise, single high‑dose irradiation directly targeting the tumor bed during surgery. In comparison with traditional external beam RT, it minimizes damage to other normal tissues, ensures an adequate dose to the tumor bed and results in improved cosmetic outcomes and quality of life. Furthermore, IORT offers a shorter treatment duration, lower economic costs and therapeutic efficacy comparable with traditional RT. However, its relatively higher local recurrence rate limits its further clinical applications...

Heat shock protein 70 (HSP70) functions as an ATP‑dependent molecular chaperone under stress and is involved in protein homeostasis, folding and degradation. HSP70 inhibitors amplify TGF‑β‑stimulated VEGF synthesis in the mouse osteoblastic MC3T3‑E1 cell line. Basic fibroblast growth factor (bFGF) stimulates IL‑6 release via p38 MAPK in MC3T3‑E1 osteoblast‑like cells. In the present study, the effects of HSP70 on the bFGF‑stimulated release of IL‑6 was evaluated using MC3T3‑E1 osteoblast‑like cells...

Several studies have revealed that an imbalance of the intestinal microbiota is involved in intestinal inflammation associated with ulcerative colitis (UC). Therefore, regulating the homeostasis of gut microbiota is critical for treating UC. Dracocephalum moldavica L. (DML) extract, a common traditional Chinese medicine, has been demonstrated to possess numerous pharmacological effects, such as antioxidative, anti‑inflammatory, and antibacterial properties. The aim of the present study was to evaluate the beneficial effects of DML extract and the probable mechanism of action in a dextran sulfate sodium‑induced chronic colitis model...
