Potentiation of Catalase-Mediated Plant Thermotolerance by N-Terminal Attachment of Solubilizing/Thermostabilizing Fusion Partners.

Catalase (CAT) plays a crucial role in plant responses to environmental stresses and maintaining redox homeostasis. However, its putative heat lability might compromise its activity and function, thus restricting plant thermotolerance. Herein, we verified Arabidopsis CAT3 was of poor thermostability that was then engineered by fusion expression in .

Phosphatase LHPP confers prostate cancer ferroptosis activation by modulating the AKT-SKP2-ACSL4 pathway.

LHPP, a novel, recognized tumor suppressor, exerts a critical influence on the regulation of tumor cell proliferation and survival by modulating various signaling pathways with its phosphatase activity. Here, we unveil a robust correlation between reduced LHPP expression and adverse prognosis in prostate cancer. We demonstrate that LHPP interacts with AKT, thereby dampening AKT phosphorylation and subsequently inhibiting ACSL4 phosphorylation at the T624 site.

Enzalutamide inhibits PEX10 function and sensitizes prostate cancer cells to ROS activators.

Sharply increased reactive oxygen species (ROS) are thought to induce oxidative stress, damage cell structure and cause cell death; however, its role in prostate cancer remains unclear. Enzalutamide is a widely used anti-prostate cancer drug that antagonizes androgen binding with its receptor. Further exploration of the mechanism and potential application strategies of enzalutamide is crucial for the treatment of prostate cancer.

SYT4 binds to SNAP25 to facilitate exosomal secretion and prostate cancer enzalutamide resistance.

Prostate carcinoma represents a predominant malignancy affecting the male population, with androgen deprivation therapy (ADT) serving as a critical therapeutic modality for advanced disease states, but it often leads to the development of resistance. Enzalutamide (Enz), a second-generation antiandrogen drug, initially offers substantial therapeutic benefit, but its efficacy wanes as drug resistance ensues. In this study, we found that synaptotagmin 4 (SYT4) is an upregulated gene in enzalutamide-resistant (EnzR) cell lines.

8-Br-cGMP activates HSPB6 and increases the antineoplastic activity of quinidine in prostate cancer.

Heat shock protein family B [small] member 6 (HSPB6), widely found in various muscles, has been recently identified as a tumor suppressor gene. However, its role in prostate cancer remains unexplored. Herein, we investigated the expression of HSPB6 in prostate cancer and its association with prognosis.

TrkA promotes MDM2-mediated AGPS ubiquitination and degradation to trigger prostate cancer progression.

Background: As a novel necrosis manner, ferroptosis has been increasingly reported to play a role in tumor progression and treatment, however, the specific mechanisms underlying its development in prostate cancer remain unclear. Growing evidence showed that peroxisome plays a key role in ferroptosis. Herein, we identified a novel mechanism for the involvement of ferroptosis in prostate cancer progression, which may provide a new strategy for clinical treatment of prostate cancer.

Transcriptomic insights into UTUC: role of inflammatory fibrosis and potential for personalized treatment.

Background: Upper tract urothelial carcinoma (UTUC) is a rare disease, belonging to the same category of urothelial cancers as bladder cancer (BC). Despite sharing similar non-surgical treatment modalities, UTUC demonstrates a higher metastasis propensity than BC. Furthermore, although both cancers exhibit similar molecular disease emergence mechanisms, sequencing data reveals some differences.

Antibody-drug conjugates in urinary tumors: clinical application, challenge, and perspectives.

Urinary tumors primarily consist of kidney, urothelial, and prostate malignancies, which pose significant treatment challenges, particularly in advanced stages. Antibody-drug conjugates (ADCs) have emerged as a promising therapeutic approach, combining monoclonal antibody specificity with cytotoxic chemotherapeutic payloads. This review highlights recent advancements, opportunities, and challenges in ADC application for urinary tumors.

Prediction for recurrent non-muscle invasive bladder cancer.

Non-muscle invasive bladder cancer (NMIBC) has a high recurrence rate, which places a significant burden on both patients and the healthcare system. Hence, it holds significant importance to predict the recurrence risk following treatment for individuals diagnosed with non-muscle invasive bladder cancer (NMIBC). As new generation technologies continue to emerge, an increasing number of recurrence risk prediction tools are being developed and discovered.

FGF21 impedes peripheral myelin development by stimulating p38 MAPK/c-Jun axis.

Fibroblast growth factor 21 (FGF21) as a metabolic stress hormone, is mainly secreted by the liver. In addition to its well-defined roles in energy homeostasis, FGF21 has been shown to promote remyelination after injury in the central nervous system. In the current study, we sought to examine the potential roles of FGF21 in the peripheral nervous system (PNS) myelination.

[Arthroscopic GraftLink technique reconstruction combined with suture anchor fixation for anterior cruciate ligament and medial collateral ligament injuries].

Objective: To investigate the effectiveness of arthroscopic GraftLink technique reconstruction combined with suture anchor fixation in treatment of anterior cruciate ligament (ACL) rupture and medial collateral ligament (MCL) grade Ⅲ injury.

Methods: Between June 2015 and February 2018, 28 patients with ACL rupture and MCL grade Ⅲ injury were treated. Arthroscopic GraftLink technique was used to reconstruct ACL with autologous peroneus longus tendon (PLT), and suture anchor fixation was used to repair MCL.

[Comparison and analysis of clinical effects of total arthroscopic repair and arthroscopic-assisted small incision repair for the treatment of rotator cuff injury].

Objective: To investigate the clinical effects of arthroscopic repair and arthroscopic-assisted small incision repair for the treatment of rotator cuff injury.

Methods: The clinical data of 86 patients with rotator cuff injury from January 2012 to January 2015 were analyzed retrospectively. All the patients were divided into two groups: arthroscopic assisted small incision repair group(group A) and arthroscopic repair group(group B).

Patients with multiple sclerosis show increased oxidative stress markers and somatic telomere length shortening.

Lipid peroxidation due to oxidative stress (OS) may play an important role in the pathogenesis of chronic systemic inflammatory diseases such as multiple sclerosis (MS). Telomeres, repeated sequences that cap chromosome ends, undergo shortening with each cycle of cell division, resulting in cellular senescence. Research regarding telomere shortening has provided novel insight into the pathogenesis of various diseases.

Rare pulmonary primitive neuroectodermal tumor metastasizing to the right atrium: a case report.

A 28-year-old man complained of intermittent irritable dry cough for 2 months with occasional bloody sputum. Positron emission tomography-computed tomography (PET-CT) suggested multiple heterogeneous soft tissue masses in the inferior lobes of both lungs, with heterogeneous increases in 18F-FDG uptake. No metabolic disorders were found in the rest of the body.

[Clinical significance of expressions of tumor markers in peripheral blood in non-small cell lung cancer].

Objective: To investigate the expressions of BJ-TSA-9, CK19 and Pre-proGRP mRNA in peripheral blood from the patients with non-small cell lung cancer and analyze their correlations with non-small cell lung cancer.

Methods: The expressions of BJ-TSA-9, CK19 and Pre-proGRP mRNA were detected by nested reverse transcription-PCR assay in peripheral blood from the patients with non-small cell lung cancer (n = 120), benign pulmonary disease (n = 106) and from healthy subjects (n = 80) so as to further investigate their relationship with clinicopathological features and prognosis. Meantime we also examined the sensitivity, specificity and accuracy of combination detection.
