A potential impact of SARS-CoV-2 on pituitary glands and pituitary neuroendocrine tumors.

Introduction: Angiotensin-converting enzyme 2 (ACE2) is the receptor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The effects of SARS-CoV-2 on normal pituitary glands function or pituitary neuroendocrine tumors (PitNETs) have not yet been elucidated. Thus, the present study aimed to investigate the potential risks of SARS-CoV-2 infection on the impairment of pituitary glands and the development of PitNETs.

Knockdown of TRIM32 inhibits tumor growth and increases the therapeutic sensitivity to temozolomide in glioma in a p53-dependent and -independent manner.

Tripartite motif protein 32 (TRIM32), an E3 ubiquitin ligase, has been reported to participate in many human cancers. However, the underlying role of TRIM32 in glioma remains largely unknown. Here, we aimed to explore the function of TRIM32 in glioma cells and the clinical implications and found that TRIM32 was upregulated in glioma tissues.

The KBTBD6/7-DRD2 axis regulates pituitary adenoma sensitivity to dopamine agonist treatment.

Pituitary adenoma (PA) is one of the most common intracranial tumors, and approximately 40% of all PAs are prolactinomas. Dopamine agonists (DAs), such as cabergoline (CAB), have been successfully used in the treatment of prolactinomas. The expression of dopamine type 2 receptor (DRD2) determines the therapeutic effect of DAs, but the molecular mechanisms of DRD2 regulation are not fully understood.

MATN1-AS1 promotes glioma progression by functioning as ceRNA of miR-200b/c/429 to regulate CHD1 expression.

Objectives: Long non-coding RNA (lncRNA) MATN1-AS1 is a newfound lncRNA that has been rarely explored in cancers. Herein, we would like to investigate its role in glioma.

Materials And Methods: qRT-PCR was conducted to examine gene expression in glioma.

Multidisciplinary team efforts improve the surgical outcomes of sellar region lesions during pregnancy.

Purpose: Treatment of space-occupying lesions (SOLs) in the sellar region is a clinical challenge, especially in pregnant women because many treatment decisions are restrained due to pregnancy. We attempt to discuss the surgical indications and timing for pregnant patients and highlight the importance of multidisciplinary team (MDT) treatment.

Methods: From August 2017 to February 2018, four pregnant women were admitted to our hospital with severe visual impairment due to sellar region SOLs, including two cases of tuberculum sellae meningioma, one case of giant pituitary adenoma and one case of a pituitary abscess.

Exosome-Transmitted lncRNA H19 Inhibits the Growth of Pituitary Adenoma.

Context: Our previous study demonstrated that the expression of long noncoding RNA (lncRNA) H19 was frequently downregulated in human primary pituitary adenomas and negatively correlated with tumor progression. However, the role of exosomal lncRNA H19 in the inhibition of pituitary tumor growth remains unclear.

Objective: To investigate whether exosomal H19 could be transported across the cell membrane to exert its inhibitory effect on pituitary tumor growth.

DEPTOR inhibits cell proliferation and confers sensitivity to dopamine agonist in pituitary adenoma.

DEP domain-containing mechanistic target of rapamycin (mTOR)-interacting protein (DEPTOR) is an important modulator of mTOR, a highly conserved kinase whose hyperactivation is critically involved in a variety of human tumors. The role of DEPTOR playing in pituitary adenoma (PA) is largely unknown. Here, we reported that DEPTOR was downregulated in PA tissues, especially dopamine-resistant prolactinomas.

Treatment of recurrent malignant gliomas with 13-cis-retinoic acid naphthalene triazole.

Glioblastoma multiforme and anaplastic astrocytoma are challenges to clinical biologists at present. The patients with glioblastoma have median survival of less than 12 months, despite advances in radiotherapeutical, chemotherapeutical and conventional surgical modalities. Retinoic acids are known to effect in vitro proliferation, differentiation, and apoptosis in colon, prostate, lung, and leukemia cancers.

Neutrophil gelatinase-associated lipocalin as an early marker of acute kidney injury in patients with traumatic brain injury.

Background: Recent studies have shown that urinary neutrophil gelatinase-associated lipocalin (NGAL) is rapidly up-regulated early after murine renal injury, and in patients after cardiac surgery or patients critically ill with multiple trauma. In this study, we evaluated urinary NGAL levels as a potential biomarker of early acute kidney injury (AKI) in patients with severe traumatic brain injury (TBI).

Methods: All patients with severe TBI admitted to our neurosurgical intensive care unit from March to September 2011 were enrolled prospectively.
