Hedgehog pathway negatively regulated depleted uranium-induced nephrotoxicity.

Depleted uranium (DU) retains the radiological toxicities, which accumulates preferentially in the kidneys. Hedgehog (Hh) pathway plays a critical role in tissue injury. However, the role of Hh in DU-induced nephrotoxicity was still unclear.

Association of Anxiety and Depressive Symptoms with Thyroid Hormone Concentrations in Patients with Primary Bone Tumors.

Background: Timely identification and intervention of psychological disorders bear significant import in ameliorating the ensuing therapeutic trajectories in primary bone tumor patients. Moreover, perturbations in thyroxine and thyroid-stimulating hormone (TSH) levels have been linked to manifestations of depressive and anxiety-related symptoms. However, the precise interplay governing the nexus of anxiety, depression, and the levels of thyroxine and TSH within the context of primary bone tumor patients remains presently unexplored.

Role of NF-κB signaling pathway in hexavalent chromium-induced hepatotoxicity.

Hexavalent chromium Cr (VI) is a primary human carcinogen with damaging toxic effects on multiple organs. Cr (VI) exposure can induce hepatotoxicity through oxidative stress, but its exact mechanism of action was still unclear. In our study, a model of acute Cr (VI) induced liver injury was established by exposing mice to different concentrations (0, 40, 80, and 160 mg/kg) of Cr (VI); RNA-seq was used to characterize changes in liver tissue transcriptome of C57BL/6 mice after exposing to 160 mg/kg Bw of Cr (VI).

ISL1/SHH/CXCL12 signaling regulates myogenic cell migration during mouse tongue development.

Migration of myoblasts derived from the occipital somites is essential for tongue morphogenesis. However, the molecular mechanisms of myoblast migration remain elusive. In this study, we report that deletion of Isl1 in the mouse mandibular epithelium leads to aglossia due to myoblast migration defects.

CKAP2 overexpression correlates with worse overall survival in patients with lung adenocarcinoma.

Background: Adenocarcinoma is a non-small-cell lung cancer that is common cancer in both genders, and has poor clinical outcomes. We aimed to evaluate the role of cytoskeleton-associated protein 2 (CKAP2), its prognostic significance, and the relationship between CKAP2 expression and lung adenocarcinoma driver genes.

Methods: The expression of CKAP2 was studied by immunohistochemical staining of specimens from 88 patients with lung adenocarcinoma.

Hexavalent chromium induces hepatocyte apoptosis via regulation of apoptosis signal-regulating kinase 1/c-Jun amino-terminal kinase signaling.

With the spread of hexavalent chromium (Cr(VI)) contamination, Cr(VI)-induced hepatotoxicity has attracted increasing attention in recent years. To date, however, the exact mechanism of Cr(VI) toxicity remains unclear. In this study, we investigated the role of apoptosis signal-regulating kinase 1 (ASK1)/c-Jun amino-terminal kinase (JNK) in Cr(VI)-induced hepatic toxicity and the possible related mechanisms.

ISLET1-Dependent β-Catenin/Hedgehog Signaling Is Required for Outgrowth of the Lower Jaw.

Mandibular patterning information initially resides in the epithelium during development. However, how transcriptional regulation of epithelium-derived signaling controls morphogenesis of the mandible remains elusive. Using to target the mandibular epithelium, we ablated transcription factor , resulting in a distally truncated mandible via unbalanced cell apoptosis and decreased cell proliferation in the distal mesenchyme.

Expression and regulation of the differentiation regulators ERBB Receptor Feedback Inhibitor 1 (ERRFI1) and Interferon-related Developmental Regulator 1 (IFRD1) during the periovulatory period in the rat ovary.

The current study investigated the regulation and the spatiotemporal expression pattern of Errfi1 and Ifrd1, genex encoding factors that regulate differentiation and cessation of cell division, in the rat ovary during the periovulatory period. Immature female rats (22-23 days old) were injected with pregnant-mare serum gonadotropin to stimulate folliculogenesis, followed by human chorionic gonadotropin (hCG) to induce ovulation. Ovaries, granulosa cells, theca-interstitial cells, or cumulus oocyte complexes (COCs) were collected at various times after hCG administration (n = 3 per time point).
