Research suggests that cathepsins, due to their extensive mechanisms of action, may play a crucial role in cardiomyopathies. However, further studies are necessary to establish causality. This study aims to investigate the causal relationship between cathepsins and various types of cardiomyopathies.

Background: The incidence and mortality of non-small cell lung cancer (NSCLC) are extremely high. Previous research has confirmed that the signal transducer and activator of the transcription 3 (STAT3) protein critically participate in the tumorigenesis of NSCLC. Mebendazole (MBZ) has exerts a larger number of pharmacological activities and has anticancer effects in lung cancer, but its mechanism of action remains unclear.

Purpose: To explore the correlation between financial toxicity, social support, and social functioning in post-chemotherapy breast cancer patients, as well as any possible interaction of financial toxicity and social support on social functioning.

Methods: Post-chemotherapy breast cancer patients admitted to the thyroid and breast surgery departments of three first-class general hospitals in East China from December 2020 to January 2022 were recruited by convenience sampling for a cross-sectional survey. The survey instruments included the general information form, the comprehensive scores for financial toxicity based on the patient-reported outcome measures (COST-PROM), the social roles and activity participation subscale from the patient-reported outcomes measurement system-breast-chemotherapy (PROMS-B-C) (score range: 8-40), and the social support subscale from PROMS-B-C (score range: 16-80).

The attenuation of bacterial metabolism provides an adjunct to the treatment of bacterial infections. To develop a bacterial eradication agent, a bioactivatable material (BP@Eu-TCPP) was designed and synthesized by coordination and reduction of europium(III) with thin-layer black phosphorus (BP) and tetrakis (4-carboxyphenyl) porphyrin (TCPP). The existence of the P-Eu bond and Eu 3d in X-ray photoelectron spectroscopy confirmed the successful synthesis of BP@Eu-TCPP.

Objective: To investigate the effect of aromatherapy on sleep quality in cancer patients.

Methods: Published literature on the effect of aromatherapy in cancer patients with sleep disorders in the form of randomized controlled trials (RCTs) were systematically retrieved and screened from PubMed, Cochrane Library, Embase, CBM, CNKI, VIP, and Wanfang databases from inception to November 2021. The methodological quality of the included studies was critically and independently evaluated by two reviewers using the Cochrane Risk of Bias Assessment Tool for RCTs.

Background: Osteosarcoma is one of the most common primary malignant bone tumors and is more common in adolescents. The femur is the most common site of osteosarcoma, and many patients require total femur replacement. We reviewed the relevant literature and case findings, summarized and analyzed this case in combination with relevant literature, and in doing so improved the understanding of the technology.

Objectives: The purpose of this network meta-analysis (NMA) is to compare the effect of several psychosocial therapies on CRF critically.

Methods: We applied systematic strategies based on eight databases, namely the Cochrane Central Register of Controlled Trials, PubMed, Embase, PsycINFO, China Biology Medicine (CBM), Wan Fang database, VIP, and China National Knowledge Infrastructure (CNKI) database to preliminary literature retrieval to identify relevant randomized controlled trials (RCTs). Studies, including adult patients (≥18 years) diagnosed with cancer, were eligible regardless of cancer stage and current treatment.

The endoplasmic reticulum unfolded protein response (UPR) is a conserved adaptive signaling in ER homeostasis and has emerged as critical in highly proliferating cells and potential treatment target for acute T-cell lymphoblastic leukemia (T-ALL). in this study, we assessed the transcriptomic and phenotypic alterations in UPR response of the bone marrow endothelial cells (ECs) in mice engrafted with T-ALL and in bone marrow specimens from patients who have T-ALL. We used PERK inhibitor and generated endothelial specific PERK knockout mice to study the impact of PERK on leukemia progression and hematopoiesis.

Background: The most ordinary subtype of lung cancer is lung adenocarcinoma (LuAC), which is characterized by strong metastatic ability. And LuAC rates in Xuanwei leads to the poor prognosis and high death rate. In this study, we systematically explored the molecular mechanism of LuAC bone metastasis in Xuanwei by transcriptome sequencing.

Article Synopsis
  • Phthalates, harmful chemicals linked to breast cancer, can enter aquatic ecosystems and accumulate in organisms through the food chain, prompting the need for effective detection methods.
  • The researchers developed a new fluorescent sensor called BANP, which can detect dibutyl phthalate (DBP) in water with a sensitivity of 0.13 μg/g and has successfully identified DBP in contaminated fish meat.
  • BANP not only detects DBP but also monitors its effects on human breast cancer cells, as the release of andrographolide from DBP-treated cells inhibits their growth, highlighting its potential for environmental and health applications.

Objective: Angiogenic factor AGGF1 (angiogenic factor with G-patch and FHA [Forkhead-associated] domain 1) promotes angiogenesis as potently as VEGFA (vascular endothelial growth factor A) and regulates endothelial cell (EC) proliferation, migration, specification of multipotent hemangioblasts and venous ECs, hematopoiesis, and vascular development and causes vascular disease Klippel-Trenaunay syndrome when mutated. However, the receptor for AGGF1 and the underlying molecular mechanisms remain to be defined.

Approach And Results: Using functional blocking studies with neutralizing antibodies, we identified [alpha]5[beta]1 as the receptor for AGGF1 on ECs.

Distant metastasis is the main cause of death for cancer patients. Recently, the newly discovered programmed cell death includes necroptosis, pyroptosis, and ferroptosis, which possesses an important role in the process of tumor metastasis. At the same time, it is widely reported that non-coding RNA precisely regulates programmed death and tumor metastasis.
