BACKGROUND/AIMS: Long noncoding RNAs (lncRNAs) are aberrantly expressed in multiple malignant tumors involved in tumor growth and metastasis. Accumulating data show that small nucleolar RNA host gene (SNHG) 1/12/20 plays a key role in the progression of hepatocellular carcinoma (HCC). However, the molecular mechanisms by which SNHG8 contributes to HCC remain elusive and merit exploration. METHODS: The association between SNHG8 expression and the clinicopathological characteristics and prognoses in HCC patients was analysed by using qRT-PCR analysis and the data from The Cancer Genome Atlas...

BACKGROUND/AIMS: Mesenchymal stromal cells (MSCs) hold considerable promise in bone tissue engineering, but their poor survival and potency when in vivo implanted limits their therapeutic potential. For this reason, the study on culture conditions and cellular signals that can influence the potential therapeutic outcomes of MSCs have received considerable attention in recent years. Cell maintenance under hypoxic conditions, in particular for a short period, is beneficial for MSCs, as low O2 tension is similar to that present in the physiologic niche, however the precise mechanism through which hypoxia preconditioning affects these cells remains unclear...

BACKGROUND/AIMS: TNF-related apoptosis-inducing ligand (TRAIL) is a novel and low-toxic anti-tumor drug used for various cancers. However, cancer cells usually develop mechanisms to acquire the resistance against TRAIL. Among these changes, dysregulation of microRNAs (miRNAs) usually occurs in cancer cells and is responsible for induction of drug resistance. METHODS: Expression of miR-494 in gastric cancer tissues and cell lines was detected by quantitative reverse transcriptase real time PCR (qRT-PCR) analysis...

BACKGROUND: Enhanced Recovery After Surgery (ERAS) protocols are multimodal perioperative care pathways designed to achieve early recovery after surgical procedures by maintaining preoperative organ function and reducing profound stress responses following surgery [Wilmore and Kehlet: BMJ 2001; 322(7284): 473-6]. Glucagon-like peptide-1 receptor agonists (GLP-1RAgs), such as liraglutide, have recently been widely used as antidiabetic agents in patients with type 2 diabetes (T2D) because they maintain blood glucose at an ideal level throughout the day, including during postprandial periods, thereby improving hypoglycemia and body weight more than insulin therapies...

Multiple sclerosis is an autoimmune neurodegenerative disease, which usually caused by inflammation, demyelination, and axonal injury. The currently available medications for multiple sclerosis do not directly promote myelin sheath repair. Therefore, many researches have attempted to achieve better therapeutic effects through promoting remyelination. Natural products not only alleviate clinical symptoms, but also have the unique advantages of protecting and repairing effects on nervous system. We here present a systematic review on published papers about treating multiple sclerosis by natural products, aiming to provide comprehensive information on natural products in the treatment of multiple sclerosis...

Conventional chemotherapy suffers from several drawbacks, including toxic side effects together with the development of resistance to the chemical agents. Therefore, exploring alternative therapeutic approaches as well as developing targeted delivery systems are in demand. Oligonucleotide-based therapy has emerged as a promising and alternative procedure for treating malignancies involving gene-related diseases. In the current study, a targeted delivery system was designed to target cancer cells based on two biocompatible polymers of poly (β amino ester) (PβAE) and poly (d, l-lactide-co-glycolide) (PLGA)...

BACKGROUND: Sirolimus is increasingly investigated as a new targeted therapy in pediatric populations. To date, population pharmacokinetic (PK) studies have identified several factors that explain in part the large between-patient variability in sirolimus PK. However, within-patient variability in sirolimus PK is not well documented. This study presents examples of model-based PK-guided dosing of sirolimus in children with acute lymphoblastic leukemia (ALL), where patients experienced significant changes in sirolimus blood concentrations due to infection and food intake during the treatment period...

Acquired resistance to chemotherapy is a frequent challenge in cancer care and one of the leading causes for failing breast cancer therapies. There is accumulative clinical and experimental evidence indicating that microRNAs (miRNAs) play a crucial role in developing therapeutic resistance in cancer cells. We aimed to explore key miRNAs and associated mechanisms by which breast cancer develops chemoresistance. In this study, we found that a particular miRNA species, miR-181c, was significantly low-expressed in breast cancer cell line MCF-7 which developed chemoresistance towards doxorubicin (Adriamycin, ADR, subclone renamed as MCF-7/ADR) than in the wild-type MCF-7 cells...

BACKGROUND: Perioperative therapeutic plasma exchange in patients with cardiovascular diseases poses several challenges, including alterations in intravascular volume, serum electrolytes, the coagulation cascade, and drug pharmacokinetics. METHODS: This review article summarizes different indications of plasma exchange for patients requiring cardiac surgery based on reported case reports and case series. RESULTS: The most common reported indication is plasma exchange for the management of allosensitized cardiac transplant candidate patients in combination with immunosuppressive regimens, which increases the likelihood of obtaining a cross-match-negative allograft, improving post-transplant clinical outcome...

Cisplatin (DDP)-based chemotherapy is a standard strategy for ovarian cancer (OC), while chemoresistance remains a major therapeutic challenge. Transcription factor SOX9 has been reported to be associated with tumor cell proliferation, metastasis, and chemoresistance. In the current study, we observed a higher SOX9 expression in OC cell lines; SOX9 overexpression might aggravate the chemoresistance of the OC cell to DDP, whereas its knockdown enhanced the chemoresistance. We screened for candidate microRNAs (miRNAs) which might target SOX9 using online tools and further verified the effect of miR-34c, one of the candidate miRNA that significantly inhibited SOX9 expression, in the regulation of OC cell proliferation and chemoresistance to DDP...

The newborn infant with severe cardiac failure owed to congenital structural heart disease or cardiomyopathy poses a daunting therapeutic challenge. The ideal solution for both might be cardiac transplantation if availability of hearts was not limiting and if tolerance could be induced, obviating toxicity of immunosuppressive therapy. If one could safely and effectively exploit neonatal tolerance for successful xenotransplantation of the heart, the challenge of severe cardiac failure in the newborn infant might be met...

Combination chemotherapy must strike a difficult balance between safety and efficacy. Current regimens suffer from poor therapeutic impact because drugs are given at their maximum tolerated dose (MTD), which compounds the toxicity risk and exposes tumors to non-optimal drug ratios. We developed a modular framework that selectively delivers drug combinations at synergistic ratios via tumor-targeting aptamers for effective low-dose treatment. Specifically, we coupled a nucleolin recognizing aptamer to peptide scaffolds laden with precise ratios of doxorubicin (DOX) and camptothecin (CPT)...

β-d-Mannuronic acid (M2000), a novel non-steroidal anti-inflammatory drug (NSAID) with immunosuppressive properties, has been previously shown to exhibit potential therapeutic effects on autoimmune diseases. Immunosuppression therapy has been a standard approach for myelodysplastic syndrome (MDS) for many years. We evaluated the effect of M2000 on isolated peripheral blood mononuclear cells (PBMCs) from patients with MDS. The PBMCs were isolated from 13 patients with MDS and 13 normal donors. The cells were then treated with low, moderate, and high doses of M2000 and diclofenac as a control group...
