Risk Factors, Prognosis, and a New Nomogram for Predicting Cancer-Specific Survival Among Lung Cancer Patients with Brain Metastasis: A Retrospective Study Based on SEER.

Purpose: To make a comprehensive population-based study on risk and prognostic factors of brain metastasis from lung cancer.

Methods: A total of 91,643 patients diagnosed with lung cancer from 2010 to 2018 were collected from the Surveillance, Epidemiology and End results (SEER) database. To analyze the risk and prognostic factors of brain metastasis among lung cancer patients, both Logistic and Cox regression methods were applied, respectively.

Discovery of the antitumor activities of a potent DCN1 inhibitor compound 383 targeting LSD1 in gastric cancer.

Dual target compounds have become a hot spot in the treatment of cancer in recent years. Histone lysine specific demethylase 1 (LSD1) is identified as histone demethylase and acts as a key regulator involved in many other cellular activities through its demethylation function. We have reported a triazolo [1,5-α] pyrimidine-based DCN1(defective in cullin neddylation protein 1) inhibitor compound 383 (IC = 11 nM) which could selectively inhibit Cullin 3/1 neddylation in MGC-803 cells.

An Update of Lysine Specific Demethylase 1 Inhibitor: A Patent Review (2016-2020).

Background: As a FAD (Flavin Adenine Dinucleotide) - dependent histone demethylase discovered in 2004, LSD1 (lysine-specific demethylase 1) was reported to be overexpressed in diverse tumors, regulating target genes transcription associated with cancer development. Hence, LSD1 targeted inhibitors may represent a new insight in anticancer drug discovery. For these reasons, researchers in both the pharmaceutical industry and academia have been actively pursuing LSD1 inhibitors in the quest for new anti-cancer drugs.

Design, synthesis, and biological evaluation of novel dual inhibitors targeting lysine specific demethylase 1 (LSD1) and histone deacetylases (HDAC) for treatment of gastric cancer.

LSD1 and HDAC are physical and functional related to each other in various human cancers and simultaneous pharmacological inhibition of LSD1 and HDAC exerts synergistic anti-cancer effects. In this work, a series of novel LSD1/HDAC bifunctional inhibitors with a styrylpyridine skeleton were designed and synthesized based on our previously reported LSD1 inhibitors. The representative compounds 5d and 5m showed potent activity against LSD1 and HDAC at both molecular and cellular level and displayed high selectivity against MAO-A/B.

Discovery and synthesis of novel indole derivatives-containing 3-methylenedihydrofuran-2(3H)-one as irreversible LSD1 inhibitors.

Lysine-specific demethylase 1 (LSD1), demethylase against mono- and di - methylated histone3 lysine 4, has emerged as a promising target in oncology. More specifically, it has been demonstrated as a key promoter in acute myeloid leukemia (AML), and several LSD1 inhibitors have already entered into clinical trials for the treatment of AML. In this paper, a series of new indole derivatives were designed and synthesized based on a lead compound obtained by a high-throughput screening with our in-house compound library.

[Developments of neutrophil function and the relationship between neutrophils dysfunction and periodontitis].

Polymorphonuclear neutrophil leukocyte (PMN) is an important member of the human immune cells. Recentyears, the recognition of the PMN function and the relationship between PMN and periodontitis have been updated. Besidesthe pathogens killing and phagocytosis, PMN also play an important role in immunoregulation and proresolving.

NPA motifs play a key role in plasma membrane targeting of aquaporin-4.

The two highly conserved NPA motifs (asparagine-proline-alanine, NPA) are the most important structural domains that play a crucial role in water-selective permeation in aquaporin water channels. However, the functions of NPA motifs in aquaporin (AQP) biogenesis remain largely unknown. Few AQP members with variations in NPA motifs such as AQP11 and AQP12 do not express in the plasma membrane, suggesting an important role of NPA motifs in AQP plasma membrane targeting.
