Withaferin A inhibits Chikungunya virus nsP2 protease and shows antiviral activity in the cell culture and mouse model of virus infection.

Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus causing fever, myalgia, and debilitating joint swelling and pain, which in many patients becomes chronic. The frequent epidemics of CHIKV across the world pose a significant public health burden necessitating the development of effective antiviral therapeutics. A cellular imaging-based high-content screening of natural compounds identified withaferin A (WFA), a steroidal lactone isolated from the plant Withania somnifera, as a potent antiviral against CHIKV.

Systemic Cancer Hallmarks as Novel Markers Associated with Progression-Free Survival in Gastroenteropancreatic Neuroendocrine Tumor Patients Undergoing Peptide Receptor Radionuclide Therapy.

Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a heterogeneous group of tumors often detected at the metastatic stage. The aim of this study was to profile the peripheral blood transcriptome through RNA-Seq and investigate the association of the systemic cancer hallmarks with progression-free survival, in peptide receptor radionuclide therapy (PRRT)-treated GEP-NET patients.

Methods: The cohorts were discovery cohort [PRRT-naïve well-differentiated GEP-NETs, n = 59; age- and sex-matched healthy individuals, n = 38], and independent evaluation cohort [GEP-NETs, n = 66].

Epidermal Growth Factor Receptor (EGFR) and SMAD4 negatively correlated in the progression of gallbladder cancer in Eastern Indian patients.

Background And Introduction: Two and half percent of the Indian population suffer from gallbladder cancer (GBC). The primary factors that lead GBC are associated with mutation of several protooncogenes such as EGFR, ERBB2, Myc, and CCND1 along with dysregulation of several tumor suppressor genes such as SMAD4 and CDKN2A. Bacterial infection caused by S.
