Clonal osteoblastic cell lines with CRISPR/Cas9-mediated ablation of Pit1 or Pit2 show enhanced mineralization despite reduced osteogenic gene expression.

Bone 2021 Jun 9;151:116036. Epub 2021 Jun 9.

Department of Bone and Mineral Research, Research Institute, Osaka Women's and Children's Hospital, Osaka Prefectural Hospital Organization, Izumi, Osaka 594-1101, Japan. Electronic address:

Multiple actions of extracellular Pi on the skeletal cells are likely to be partly mediated by type III sodium/phosphate (Na/Pi) cotransporters Pit1 and Pit2, although the details are not fully understood. In the current study, to determine the roles of Pit1 and Pit2 in osteoblasts, we generated Pit1-knockout (KO) and Pit2-KO osteoblastic cells by applying CRISPR/Cas9 genome editing to an osteoblastic cell line MC3T3-E1 subclone 4. The extracellular Pi level was increased in the Pit1-KO and Pit2-KO clones due to the reduced Pi uptake. Read More

Alpha lipoic acid priming enhances the hepatoprotective effect of adipose derived stem cells in CCl4 induced hepatic injury in-vitro.

Eur J Pharmacol 2021 Jun 9:174201. Epub 2021 Jun 9.

National Centre of Excellence in Molecular Biology, University of Punjab, 87-West Canal Bank Road, Lahore, Pakistan; Jinnah Burn & Reconstructive Surgery Centre, Lahore, Pakistan. Electronic address:

Mesenchymal stem cells are known to support hepatic defense against liver fibrosis. However, the fibrosis induced oxidative microenvironment affects the proliferative, regenerative, and angiogenic properties of mesenchymal stem cells. Alpha lipoic acid (ALA) is a strong anti-oxidant which has been shown to ameliorate the adverse effects of fibrosis that otherwise can lead to severe liver problems like cirrhosis and liver failure.

RNA analysis based on a small number of manually isolated fixed cells (RNA-snMIFxC) to profile stem cells from human deciduous tooth-derived dental pulp cells.

Biol Proced Online 2021 Jun 11;23(1):12. Epub 2021 Jun 11.

Department of Genome Medicine, National Center for Child Health and Development, 2-10-1, Tokyo, 157-8535, Japan.

Background: Expression of stemness factors, such as octamer-binding transcription factor 3/4 (OCT3/4), sex determining region Y-box 2 (SOX2), and alkaline phosphatase (ALP) in human deciduous tooth-derived dental pulp cells (HDDPCs) can be assessed through fixation and subsequent immuno- or cytochemical staining. Fluorescence-activated cell sorting (FACS), a powerful system to collect cells of interest, is limited by the instrument cost and difficulty in handling. Magnetic-activated cell sorting is inexpensive compared to FACS, but is confined to cells with surface expression of the target molecule. Read More

Polymorphic variants of alkaline phosphatase gene correlate with clinical signs of adult hypophosphatasia?

Osteoporos Int 2021 Jun 7. Epub 2021 Jun 7.

Department of Experimental and Clinical Biomedical Sciences, University of Florence, Florence, Italy.

We analyzed polymorphism of the ALPL gene in patients with low serum levels of tissue-nonspecific alkaline phosphatase (TNAP). The presence of three or more of the less frequent alleles of ALPL polymorphisms was associated with significantly lower TNAP serum level and higher frequencies of metatarsal fractures, which may help confirm a clinical suspicion of adult hypophosphatasia.

Introduction: Alkaline phosphatases (ALPs) are membrane-bound enzymes that hydrolyze monophosphate esters at a high pH (pH 8-10). Read More
