This study explores the molecular mechanism by which sentrin/SUMO-specific protease 1 (SENP1) promotes cisplatin (Cis) resistance and tumor stem cell characteristics in colon adenocarcinoma (COAD) through desumoylation-mediated modification of octamer-binding transcription factor 4 (OCT4). By analyzing single-cell and transcriptome sequencing datasets, we identified key genes and regulatory pathways in both resistant and sensitive COAD cells. Malignant cells were isolated and evaluated for stemness using the infercnv package, and differential genes between Cis-resistant and -sensitive groups were identified. Machine learning algorithms highlighted essential genes, and databases predicted interaction sites between OCT4 and SENP1. experiments using enriched HCT116 stem cells revealed that SENP1 and OCT4 expression significantly elevated CD44 and CD133 levels, enhancing stemness. Functional assays showed that SENP1's desumoylation of OCT4 intensified Cis resistance, migration, and invasion in cisplatin-resistant cell line 116 (Cis-116) cells. , SENP1 knockdown reduced tumor growth and stem cell markers, while OCT4 overexpression escalated tumor metastasis and structural damage. These findings demonstrate that SENP1's modulation of OCT4 is central to COAD's resistance and stem cell properties, offering a novel target for COAD therapy.

Background: Acute kidney injury (AKI) is a serious complication after lung transplantation, but the reported incidence varies in the literature. No data on AKI have been published from the Swedish lung transplantation program.
Methods: The aim of our study was to investigate the incidence, perioperative risk factors, and effects of early postoperative acute kidney injury (Kidney Disease Improving Global Outcomes [KDIGO] criteria) after lung transplantation.

A diabetic wound is the most frequent form of chronic wound. Because diabetic wounds have multiple factors contributing to their development, the best treatments involve using a combination of approaches. Herein we assessed whether bioactive and degradable bioengineered micro-porous collagen-based three-dimensional scaffold (CTS) encapsulated with adipose mesenchymal stem cells (ASCs)-derived exosomes could accelerate the wound healing process in diabetic rats.

Introduction: Prostate cancer (PCa) is the most frequent diagnosed malignancy in male patients in Europe and radiation therapy (RT) is a main treatment option. However, current RT concepts for PCa have an imminent need to be rectified in order to modify the radiotherapeutic strategy by considering (i) the personal PCa biology in terms of radio resistance and (ii) the individual preferences of each patient.
Methods: To this end, a mechanistic multiscale model of prostate tumor response to external radiotherapeutic schemes, based on a discrete entity and discrete event simulation approach has been developed.

Introduction: The use of allogeneic peripheral blood stem cell transplantation (allo-SCT) has increased in Latin America in recent years. In the absence of an matched-related donor (MRD), haploidentical transplantation has emerged as a potentially curative option with increasing availability in the region. Graft-versus-host disease (GVHD) is an important complication with variable incidence rates depending on the type of transplant.
