Aim: To investigate the changes of proliferation and apoptosis in K562 cells over-expressing miR-10a.
Methods: K562 cells were infected with pAd-pre-miR-10a virus, and then the levels of miR-10a and bcr/abl in transfected K562 cells was detected using RT-PCR and the level of BCR/ABL using Western blotting. The methylthiazolyl tetrazolium (MTT) assay and flow cytometry (FCM) were used to monitor the changes of proliferation and apoptosis of K562 cells after transfection.
Results: Compared with the control groups, K562 cells transfected with pAd-pre-miR-10a presented the significantly increased level of miR-10a, the significantly decreased expressions of bcr/abl fusion gene and BCR/ABL fusion protein, the inhibited proliferation ability and the promoted apoptosis (P<0.05).
Conclusion: The recombinant adenovirus of pAd-pre-miR-10a can inhibit the proliferation of K562 cells and promote cell apoptosis significantly.

Background: Natural killer (NK) cells are important contributors to antitumor immunity in clear-cell renal cell carcinoma (ccRCC). However, their phenotype, function, and association with clinical outcomes in ccRCC remain poorly understood.
Materials And Methods: We analyzed single-cell RNA sequencing data from 13 primary tumors, 1 localized tumor extension, and 1 metastasis from ccRCC patients at different clinical stages.

Background: The challenges associated with traditional drug screening, such as high costs and long screening times, have led to an increase in the use of single-cell isolation technologies. Small sample volumes are required for high-throughput, cell-based assays to reduce assay costs and enable rapid sample processing. Using microfluidic chips, single-cell analysis can be conducted more effectively, requiring fewer reagents and maintaining biocompatibility.

Platelets

Department of Pharmacology and Physiology, George Washington University, Washington, DC, USA.
Platelet-like particles (PLPs), derived from megakaryocytic cell lines MEG-01 and K-562, are widely used as a surrogate to study platelet formation and function. We demonstrate by RNA-Seq that PLPs are transcriptionally distinct from platelets. Expression of key genes in signaling pathways promoting platelet activation/aggregation, such as the PI3K/AKT, protein kinase A, phospholipase C, and α-adrenergic and GP6 receptor pathways, was missing or under-expressed in PLPs.

Background: Several approaches are being explored for engineering off-the-shelf chimeric antigen receptor (CAR) T cells. In this study, we engineered chimeric Fcγ receptor (FcγR) T cells and tested their potential as a versatile platform for universal T cell therapy.
Methods: Chimeric FcγR (CFR) constructs were generated using three distinct forms of FcγR, namely CD16A, CD32A, and CD64.

l-Asparaginase (l-ASNase) catalyzes the hydrolysis of l-asparagine, leading to its depletion and subsequent effects on the cellular proliferation and survival. In contrast to normal cells, malignant cells that lack asparagine synthase are extremely susceptible to asparagine deficiency. l-ASNase has been successfully employed in treating pediatric leukemias and non-Hodgkin lymphomas; however, its usage in adult patients and other types of cancer is limited due to significant side effects and drug resistance.
