The huge cadre of genes regulated by Myc has obstructed the identification of critical effectors that are essential for Myc-driven tumorigenesis. Here, we describe how only the lack of the receptor Fzd9, previously identified as a Myc transcriptional target, impairs sustained tumor expansion and β-cell dedifferentiation in a mouse model of Myc-driven insulinoma, allows pancreatic islets to maintain their physiological structure and affects Myc-related global gene expression. Importantly, Wnt signaling inhibition in Fzd9-competent mice largely recapitulates the suppression of proliferation caused by Fzd9 deficiency upon Myc activation. Together, our results indicate that the Wnt signaling receptor Fzd9 is essential for Myc-induced tumorigenesis in pancreatic islets.

Acute kidney injury (AKI) is a group of common clinical syndromes characterized by a rapid decline in renal function over a short period of time. At present, the treatment methods are limited, and research is needed to identify drugs that could alleviate renal ischemia-reperfusion (I/R) injury. Tetramethylpyrazine (TMP) is a bioactive alkaloid extracted from the Chinese herbal medicine Chuanxiong.

Hepatocellular carcinoma (HCC) is a prevalent malignant neoplasm of the digestive system, including 80% of primary liver malignancies. The Wnt/β-catenin signaling pathway plays a key role in immune response and tumer resistance. A growing number of studies have shown that the Wnt/β-catenin signaling pathway is involved in the pathogenesis of HCC.

Notoginsenoside R1 (NGR1), a natural triterpenoid saponin, is extracted from , and has cardiovascular and cerebrovascular protective effects due to anti-inflammatory, anti-oxidant, and anti-apoptotic properties. Previous research has suggested a protective role for NGR1 in myocardial ischemia/reperfusion (MI/R) injury. However, the potential mechanisms involved have not been fully elucidated.

Double homeobox A pseudogene 9 (DUXAP9), also known as long intergenic non-coding RNA 1296 (LINC01296) and lymph node metastasis-associated transcript 1 (LNMAT1), is an emerging lncRNA encoded by a pseudogene. It has been reported to be upregulated in various tumor types and functions as an oncogenic factor. The high expression of DUXAP9 is closely related to clinical pathological features and poor prognosis in 16 types of malignant tumors.

Polycystic ovary syndrome (PCOS) is an endocrine-metabolic disorder characterized by ovarian dysfunction, with limited effective treatments. This study investigates the therapeutic effects and mechanisms of white kidney bean extract (WKBE) in a PCOS rat model. A PCOS model was established using letrozole, followed by intervention with varying doses of WKBE.
