Aim: Long noncoding RNAs (lncRNAs) are novel intracellular noncoding ribonucleotides regulating the genome and proteome. The lncRNA activated by transforming growth factor β (TGF-β) (lncRNA-ATB) was discovered as a prognostic factor in hepatocellular carcinoma, gastric cancer, and colorectal cancer. However, little is known about the role of lncRNA-ATB in renal transplantation. This study aimed to assess lncRNA-ATB expression in renal transplant patients with acute kidney injury and explore its role in postoperative pharmaceutical immunosuppression therapy.
Methods: We detected lncRNA-ATB expression in the kidney biopsies of a cohort of 72 patients with renal allograft rejection and 36 control transplant patients. lncRNA-ATB were overexpressed from lentiviral vectors in renal cells.
Results: We found that lncRNA-ATB was remarkably upregulated in patients with acute rejection compared with controls. Meanwhile, lncRNA-ATB could influence the kidney cell phenotypes and impact the nephrotoxicity of immunosuppressive drug.
Conclusion: In conclusion, lncRNA-ATB are strongly altered in patients with acute rejection and may serve as a novel biomarker of acute kidney rejection, identifying patients with acute rejection and predicting loss of kidney function.

Background: Interpersonal injury disproportionately impacts marginalized communities. Crime Victim Compensation (CVC) was developed in Canada and the United States to help individuals and their families following violent injury. In Illinois, the CVC program offers up to $27,000 per claim to assist with mental health, relocation, and burial expenses.

Background: Patients with end-stage renal disease often face prolonged waiting times for kidney transplants. Historically, the use of marginal kidneys was limited due to suboptimal preservation methods. Normothermic machine perfusion (NMP) preserves physiological activity during the preservation process, potentially improving graft function and viability, expanding the use of marginal kidneys.

Acute kidney injury (AKI) in paediatric kidney transplant recipients is common. Infection including urinary tract infection (UTI) and rejection are the most common causes in children. Surgical complications often cause AKI early post-transplant, whereas BK polyomavirus nephropathy rarely occurs in the first month post-transplant.

Donor-specific antibodies (DSAs) are essential causes of graft rejection in haploidentical hematopoietic stem cell transplantation (haplo-HSCT). DSAs are unavoidable for some patients who have no alternative donor. Effective interventions to reduce DSAs are still needed, and the cost of the current therapies is relatively high.

Background: Inadequate treatment of acute rejection (AR) in pediatric kidney transplant recipients (KTR) can contribute to early allograft failure. Serum creatinine is an insensitive marker of allograft function, especially in the pediatric population, and may not detect ongoing rejection after treatment. We evaluated the utility of follow-up biopsies to detect persistent inflammation and future episodes of rejection.
