ABSTRACT

Sporadic Alzheimer's disease (sAD) is the most common neurodegenerative disease worldwide, which is characterized by the progressive cognitive dysfunction and behavioral impairment. Here, we generated a human induced pluripotent stem cell (iPSC) line from the peripheral blood mononuclear cells (PBMCs) isolated from a 78-year-old male patient clinically diagnosed with sAD. The iPSC line expressed pluripotency markers, showed normal karyotype, and had the ability to differentiate into three germ layers in vitro. This iPSC line may provide a powerful tool for modeling AD in vitro and studying the pathogenesis of sAD.

ABSTRACT

Apolipoprotein E (APOE) gene encodes three protein isoforms (APOEε-22/ε-33/ε-44), which governs the transportation and metabolism of lipoproteins differently. While abnormalities in lipid and lipoprotein metabolism have been identified as risk factors for type 2 diabetes mellitus (T2DM). APOE gene polymorphisms might be correlated with increased risk of T2DM. Therefore, we presented an iPSC line harboring an APOE-ε3/ε3 alleles, a male donor suffering from T2DM combined with Hypertension. The derived iPSCs showed pluripotency, the capacity to differentiate into three germ layers, and normal karyotypes. Collectively, the present study provides a useful resource to reveal the associated mechanism of APOE isoform and T2DM.

ABSTRACT

BACKGROUND: Many studies have shown that long noncoding RNAs (lncRNAs) are closely related to the stimulation of osteogenic differentiation of adipose-derived stem cells (ADSCs) and the prevention of osteoporosis. Current research aimed to investigate the novel lncRNA and explored the function and molecular mechanism of the LINC00314/miR-129-5p/GRM5 axis in regulating osteogenic differentiation of ADSCs. METHODS: LncRNA and miRNA sequencing was performed in normal and osteogenic differentiation-induced ADSCs (osteogenic group). Abnormally expressed lncRNAs and miRNAs were obtained by the R software and the relative expression of LINC00314, miR-129-5p, and GRM5 during osteogenic induction was measured by RT-PCR. ADSCs were then transfected with pcDNA3.1-sh-LINC00314 and agomiR-129-5p. Alizarin red staining (ARS) and alkaline phosphatase (ALP) staining were performed to identify the mechanism of the LINC00314/miR-129-5p/GRM5 axis in regulating osteogenic differentiation of ADSCs. RESULTS: LINC00314 was significantly upregulated in the group of osteogenic-induced ADSCs. LINC00314 and GRM5 mimics increased the early and late markers of osteogenic differentiation, which manifest in not only the markedly increased ALP activity but also higher calcium deposition, while miR-129-5p mimic had the opposite effects. LINC00314 directly targeted miR-129-5p through luciferase reporter assay, and miR-129-5p suppressed GRM5 expression. Moreover, the LINC00314/miR-129-5p/GRM5 regulatory axis activated the Wnt/ß-catenin signaling pathway. CONCLUSIONS: LINC00314 confers contributory function in the osteogenic differentiation of ADSCs and thus the LINC00314/miR-129-5p/GRM5 axis may be a novel mechanism for osteogenic-related disease.

ABSTRACT

Induced pluripotent stem cells (iPSCs) were generated from peripheral blood mononuclear cells (PBMCs) obtained from a 60-year-old female diagnosed with sporadic amyotrophic lateral sclerosis (sALS). The iPSCs shared the same karyotype with the parent PBMCs, expressed pluripotency stem cell markers, and demonstrated trilineage differentiation potential. This cell line could serve as an ideal model to investigate the mechanisms underlying amyotrophic lateral sclerosis (ALS).

ABSTRACT

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with the loss of upper motor neurons in the cortex and lower motor neurons in the brain stem and spinal cord regressively. The vast majority of ALS cases have no familial history are apparently sporadic (SALS), making the modeling of SALS essential to the development of ALS therapeutics. Therefore, human induced pluripotent stem cell (iPSC) from peripheral blood mononuclear cells of a 64-year-old SALS patient were produced using a virus-free protocol and characterized using standard validate methods. This generated iPSC line could be useful to reveal SALS mechanisms and screen drug development.

ABSTRACT

Induced pluripotent stem cells (iPSCs) can be used to generate different types of somatic cells in vitro, including neuronal cells. Here, a human iPSC line was generated from the peripheral blood mononuclear cells of a healthy 39-year-old individual. The resulting iPSCs were integration-free, maintained the normal karyotype, expressed pluripotency stem cell markers, and were demonstrated to be capable of differentiating into cells representative of the three embryonic germ layers. Furthermore, we showed that this iPSC line could be differentiated into neural stem cells. Taken together, this generated iPSC line could be useful to test multiple differentiation protocols, and also serve as a control for investigating drug development and disease mechanisms.

ABSTRACT

We generated a human induced pluripotent stem cell (iPSC) line from the skin fibroblasts of a 62-year-old female patient clinically diagnosed with sporadic Parkinson's disease (PD). The generated iPSCs maintained their normal karyotype, expressed pluripotency stem cell markers, and were demonstrated to be capable of differentiating into cells representative of the three embryonic germ layers. The generated line could be used for PD modeling in order to understand the mechanisms that influence the disorder.

ABSTRACT

BACKGROUND: Resistin is an adipocytokine associated with inflammation and insulin resistance. Recent studies have shown that resistin plays an important role in the pathogenesis and progression in osteoarthritis (OA) patients. The current study was aimed at investigating the relationship between resistin in serum and synovial fluid (SF) and disease severity in patients with knee osteoarthritis. METHOD: Seventy-four patients diagnosed with knee OA and 79 healthy controls receiving regular body check in our hospital were recruited in the study. The Noyes score method was used to assess articular cartilage damage arthroscopically. The symptomatic severity was evaluated according to the Western Ontario McMaster University Osteoarthritis (WOMAC) scores. The radiographic disease severity of OA was assessed by the Kellgren-Lawrence (K-L) grading system. The resistin levels in serum and SF were determined by enzyme-linked immunosorbent assay. Cartilage degradation marker CTX-II in SF was also examined. RESULTS: SF but not serum resistin levels are positively associated with Noyes scores, K-L grading scores WOMAC pain scores, physical functional scores and WOMAC total scores. In addition, SF resistin correlated positively with CTX-II. CONCLUSION: Resistin in SF might serve as a potential biomarker for reflecting the disease severity and cartilage degenerative extent of knee OA.

ABSTRACT

BACKGROUND: Elevated serum and synovial fluid (SF) YKL-40 levels have been detected in knee osteoarthritis (OA) patients. The current study was focused on the correlation between YKL-40 levels in serum or SF and symptomatic severity in patients with knee osteoarthritis. METHODS: 144 patients with knee OA and 151 healthy individuals were recruited into this study. Symptomatic severity was determined using Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores from OA patients. Serum and SF levels of YKL-40 were explored by enzyme-linked immunosorbent assay. RESULTS: We found that YKL-40 levels in SF but not serum were independently and positively related to WOMAC pain (r = 0.531, p = 0.001), physical disability (r = 0.380, p = 0.025), and total scores (r = 0.407, p = 0.01) in knee OA patients. CONCLUSIONS: YKL-40 in SF could represent a potential biomarker for assessing the symptomatic severity of OA.

ABSTRACT

OBJECTIVE: To find sensitive and specific micro-metastic markers for prostate cancer. METHODS: Using nested reverse transcription-PCR, we examined the expression of PSA, hK2 and PSMA mRNA in peripheral blood mononuclear cells of 51 patients with prostate cancer, 33 patients with benign prostate hyperplasia (BPH) and 32 normal young people. RESULTS: The expression rates of PSA, hK2 and PSMA mRNA were 52.9%, 43.1% and 64.7%, respectively in prostate cancer group, and 6.2%, 7.7% and 4.6%, respectively in control group (BPH patients and normal young people) with statistical significance (P < 0.01). Although the expression rate of PSA and hK2 mRNA increased with cancer progression, there was no statistical significance among patients in different stages. The expression rate of PSMA mRNA was higher than that of PSA and hK2 mRNA in each clinical stage. CONCLUSION: PSMA mRNA expression detected by nested RT-PCR is of greater value for the diagnosis, therapy choice and prognostic evaluation of prostate cancer patients.
