Computational modeling has been applied to simulate the heterogeneity of cancer behavior. The development of Cervical Cancer (CC) is a process in which the cell acquires dynamic behavior from non-deleterious and deleterious mutations, exhibiting chromosomal alterations as a manifestation of this dynamic. To further determine the progression of chromosomal alterations in precursor lesions and CC, we introduce a computational model to study the dynamics of deleterious and non-deleterious mutations as an outcome of tumor progression...

REVIEW
Mark D Berry, Raul R Gainetdinov, Marius C Hoener, Mohammed Shahid
The discovery in 2001 of a G protein-coupled receptor family, subsequently termed trace amine-associated receptors (TAAR), triggered a resurgence of interest in so-called trace amines. Initial optimism quickly faded, however, as the TAAR family presented a series of challenges preventing the use of standard medicinal chemistry and pharmacology technologies. Consequently the development of basic tools for probing TAAR and translating findings from model systems to humans has been problematic. Despite these challenges the last 5 years have seen considerable advances, in particular with respect to TAAR1, which appears to function as an endogenous rheostat, maintaining central neurotransmission within defined physiological limits, in part through receptor heterodimerization yielding biased signaling outputs...

Cyclin dependent kinases plays a central role in cell cycle regulation which makes them a promising target with multifarious therapeutic potential. CDK2 regulates various events of the eukaryotic cell division cycle and the pharmacological evidences indicated that over expression of CDK2 causes abnormal cell-cycle regulation, which was directly associated with hyper proliferation of cancer cells. Therefore, CDK2 is regarded as a potential target molecule for anti-cancer medication. Thus to decline CDK2 activity by potential lead compounds has proved to be an effective treatment for cancer...

Osteoporosis is a systemic skeletal disorder which occurs when the bone turnover balance is disrupted. With the identification of the genes involved in the pathogenesis of the disease, studies on development of new osteoporosis treatments has intensified. RNA interference (RNAi) mechanism uses short interfering RNA (siRNA) to knockdown disease related gene expression as a treatment approach. Targeting while protecting siRNA against hydrolysis by nucleases in vivo is, however, challenging. The maintenance of therapeutic plasma level is also hampered by the clearance of siRNA from the body...

BACKGROUND: Histone lysine demethylases (KDMs) are well-recognized targets in oncology drug discovery. They function at the post-translation level controlling chromatin conformation and gene transcription. KDM1A is a flavin adenine dinucleotide-dependent amine oxidase, overexpressed in several tumor types, including acute myeloid leukemia, neuroblastoma and non-small-cell lung cancer. Among the many known monoamine oxidase inhibitors screened for KDM1A inhibition, tranylcypromine emerged as a moderately active hit, which irreversibly binds to the flavin adenine dinucleotide cofactor...

3,4-methylenedioxymethamphetamine (MDMA; 'ecstasy') is widely consumed recreationally. Currently little is known about its effects on the human metabolome. Mapping biochemical changes after drug exposure can complement traditional approaches by revealing potential biomarkers of organ toxicity or discovering new metabolomic features in a time- and dose-dependent manner. We aimed to analyze for the first time plasma samples from a randomized, double-blind, placebo-controlled crossover study in healthy adults to explore changes in endogenous plasma metabolites following a single intake of MDMA...

There has been a dramatic increase in the emergence of antibiotic resistant bacterial strains, which has made antibiotic choices for infection control increasingly limited and more expensive. In the U.S. alone, antibiotic resistant bacteria cause at least 2 million infections and 23,000 deaths a year resulting in a $55-70 billion per year economic impact. Antibiotics are critical to the success of surgical procedures including orthopaedic prosthetic surgeries, and antibiotic resistance is occurring in nearly all bacteria that infect people, including the most common bacteria that cause orthopaedic infections, such as Staphylococcus aureus (S...

The presence of androgen receptor variant 7 (AR-V7) variants becomes a significant hallmark of castration resistant prostate cancer (CRPC) relapsed from hormonal therapy and is associated with poor survival of CRPC patients because of lacking a ligand-binding domain. Currently, it still lacks an effective agent to target AR-V7 or AR-Vs in general. Here, we showed a novel class of agents (thailanstatins, TSTs, spliceostatin A analogs) can significantly suppress the expression of AR-V7 mRNA and protein but in a less extent on the full-length AR expression...

The Food and Drug Administration in the United States issued a much-awaited draft guidance on 'Multiple Endpoints in Clinical Trials' in January 2017. The draft guidance is well written and contains consistent message on the technical implementation of the principles laid out in the guidance. In this commentary, we raise a question on applying the principles to studies designed from a safety perspective. We then direct our attention to issues related to multiple co-primary endpoints. In a paper published in the Drug Information Journal in 2007, Offen et al...

AIM: Human cytomegalovirus constitutes a prevalent and serious threat to immunocompromised individuals and requires new treatments. Letermovir is a novel viral-terminase inhibitor that has demonstrated prophylactic/preemptive activity against human cytomegalovirus in Phase 2 and 3 transplant trials. As unchanged letermovir is primarily excreted via the liver by bile, this trial aimed to assess the effect of hepatic impairment on letermovir pharmacokinetics. METHODS: Phase 1, open-label, parallel-group pharmacokinetic and safety comparison of multiple once-daily oral letermovir in female subjects with hepatic impairment and healthy matched controls...

Lupus nephritis (LN) is a major manifestation of systemic lupus erythematosus (SLE) causing morbidity and mortality in 40-60% of SLE patients. The pathogenic mechanisms of LN are not completely understood. Recent studies have demonstrated the presence of various immune cell populations in lupus nephritic kidneys of both SLE patients and lupus-prone mice. These cells may play important pathogenic or regulatory roles in situ to promote or sustain LN. Here, using lupus-prone mouse models, we showed the pathogenic role of a kidney-infiltrating CD11c(+) myeloid cell population in LN...

Clinical practice showed that some advanced gastric cancer (AGC) patients achieved long-term survival after surgery, whereas some benefited from non-surgical treatment. In recent years, with the emergence of new drugs, diversity of treatment and development of multi-disciplinary team, the concept of conversion therapy comes into attention. Owing to diverse phenotypes with scattered cases, publications are mainly case reports or small sample studies from single centers, which makes it hard to acquire high-level evidence...
