Alcoholic liver diseases and virus-induced hepatic dysfunctions are prevalent in western countries. Evidence also suggests that hyperglycemia and insulin resistance are key players in the development of hepatic diseases and their complications. Since the comorbid diseases like obesity, diabetes and vascular dysfunctions primarily affect liver, the modern therapies against other hepatic dysfunctions are becoming a major challenge to treat. In addition to these, polypharmacy and adverse drug reactions (ADRs) are further aggravating the phenomenon...

Ovarian cancer (OC) is the second most common and the most lethal of the gynecological malignancies. Currently, there exists no effective screening tool for OC. MicroRNAs (miRNAs) are endogenous 18-23 nucleotide non-coding RNAs that refine gene expression. MiRNAs have been found to be aberrantly expressed in OC tumor tissue as well as detectable in biological fluids such as the blood, urine, and ascites and have been proposed as biomarkers and therapeutic targets for OC. Areas covered: This review summarizes the current knowledge regarding the application of miRNAs as diagnostic, prognostic, and predictive biomarkers in OC...

Recent breakthroughs in next-generation sequencing technology and complementary genomic platforms have transformed our capacity to interrogate the molecular landscapes of human cancers, including childhood brain tumors. Numerous high-throughput genomic studies have been reported for the major histologic brain tumor entities diagnosed in children, including interrogations at the level of the genome, epigenome, and transcriptome, many of which have yielded essential new insights into disease biology. The nature of these discoveries has been largely platform dependent, exemplifying the usefulness of applying different genomic and computational strategies, or integrative approaches, to address specific biologic and/or clinical questions...

Patients with cancer are frequently affected by spinal metastases. Treatment is palliative, with the principle goals of pain relief, preservation of neurologic function, and improvement in quality of life. In the past decade, we have witnessed a dramatic change in the treatment paradigms due to the development of improved surgical strategies and systemic and radiation therapy. The most important change to these paradigms has been the integration of spinal stereotactic radiosurgery (SSRS), allowing delivery of tumoricidal radiation doses with sparing of nearby organs at risk...

Despite the availability of several anti-retrovirals there is still an urgent need for developing novel therapeutic strategies and finding new drugs against underexplored HIV-1 targets. Among them, there are the HIV-1 Reverse Transcriptase (RT)-associated Ribonuclease H (RNase H) function and the cellular α-glucosidase, involved in the control mechanisms of N-linked glycoproteins formation in the endoplasmic reticulum. It is known that many natural compounds, such as pentacyclic triterpenes, are a promising class of HIV-1 inhibitors...

Targeted therapies have substantially changed the management of non-small cell lung cancer (NSCLC) patients with driver oncogenes. Given the high frequency, EGFR and ALK aberrations were the first to be detected and paved the way for tyrosine kinase inhibitor (TKI) treatments. Other kinases such as ROS1 and more recently RET have emerged as promising targets, and ROS1 and RET TKIs are already available for precision medicine.We screened a large cohort of 713 Caucasian non-squamous NSCLC patients lacking EGFR/KRAS/BRAF/HER2/PI3KCA/ALK aberrations for ROS1 and RET rearrangements using fluorescence in situ hybridization to determine the frequency and clinicopathological characteristics of ROS1- and RET-positive patients...

Hepatocellular carcinoma (HCC) is the third most frequent cause of tumor-related mortality and there are an estimated approximately 850,000 new cases annually. Most HCC patients are diagnosed at middle or advanced stage, losing the opportunity of surgery. The development of HCC is promoted by accumulated diverse genetic mutations, which confer selective growth advantages to tumor cells and are called "driver mutations". The discovery of driver mutations provides a novel precision medicine strategy for late stage HCC, called targeted therapy...

New, safe and effective drugs are urgently needed to treat and control malaria and tuberculosis, which affect millions of people annually. However, financial return on investment in the poor settings where these diseases are mostly prevalent is very minimal to support market-driven drug discovery and development. Moreover, the imminent loss of therapeutic lifespan of existing therapies due to evolution and spread of drug resistance further compounds the urgency to identify novel effective drugs. However, the advent of new public-private partnerships focused on tropical diseases and the recent release of large data sets by pharmaceutical companies on antimalarial and antituberculosis compounds derived from phenotypic whole cell high throughput screening have spurred renewed interest and opened new frontiers in malaria and tuberculosis drug discovery...

In the latter part of the 20th century, drug development in cardiovascular diseases (CVDs) was a paragon of "modern" therapeutics, bringing about a substantial number of effective, well-tolerated agents targeting some of the most prevalent diseases of the Western world. These drugs were often examples of rational drug development targeting specific pathophysiologic pathways previously elucidated through basic research (e.g., targeting of the renin-angiotensin system or the cholesterol synthesis pathway). The widespread adoption of these ground-breaking medications in practice and into medical guidelines undoubtedly played a role in the fall of morbidity and mortality from CVD in the United States in recent decades...

Cancer is the 2nd leading cause of death worldwide. The development of drugs to target only one specific signaling pathway has limited therapeutic success. Developing chemotherapeutics to target multiple signaling pathways has emerged as a new prototype for cancer treatment. Deoxyelephantopin (DET) and isodeoxyelephantopin (IDET) are sesquiterpene lactone components of "Elephantopus scaber and Elephantopus carolinianus", traditional Chinese medicinal herbs that have long been used as folk medicines to treat liver diseases, diabetes, diuresis, bronchitis, fever, diarrhea, dysentery, cancer, and inflammation...

Oncoimmunology (or immunooncology) is a burgeoning specialty of precision ("personalized") medicine designed to heighten the antitumor response of the immune system against molecules expressed excessively or only by tumor cells. This focus is necessary, as cancers are polyclonal tissues comprised of antigenically heterogeneous cells, the exact composition of which is shaped by the balance between antitumor immunity and tumor-promoting inflammation. Key targets include enhancing immune system (especially T cell) reactivity, inhibiting immune checkpoints, and promoting tumor cytolysis...

The common marmoset monkey (Callithrix jacchus; Cj) is an advantageous nonhuman primate species for modeling age-related disorders, including Parkinson's disease, due to their shorter lifespan compared to macaques. Cj-derived induced pluripotent stem cells (Cj-iPSCs) from somatic cells are needed for in vitro disease modeling and testing regenerative medicine approaches. Here we report the development of a novel Cj-iPSC line derived from adult marmoset fibroblasts. The Cj-iPSCs showed potent pluripotency properties including development of mesodermal lineages in tumors after injection to immunocompromised mice, as well as ectoderm and endoderm lineages after in vitro differentiation regimens, demonstrating differentiated derivatives of all three embryonic layers...

Glioma is the most common primary malignant brain tumor and the effect of chemotherapy is hampered by low permeability across the blood-brain-barrier (BBB). Borneol is a time-honored 'Guide' drug in traditional Chinese medicine and has been proved to be capable of promoting free drugs into the brain efficiently, but there are still risks that free drugs, especially anti-glioma drugs, may be disassembled and metabolized before penetrating the BBB and caused the whole brain distribution. The purpose of this paper was to investigate whether borneol intervention could facilitate the BBB penetration and assist glioma treatment by combining with doxorubicin (DOX) loaded PAMAM dendrimers drug delivery system modified with Angiopep-2 (a ligand of the low-density lipoprotein receptor-related protein, which overexpress both in the BBB and gliomas)...

Our recent biosystems analysis revealed similarities between embryonic implantation and cancer cell adhesion, which suggests that abortifacients may be good for safe and effective metastatic chemoprevention targeting circulating tumor cells (CTC). Here we test the hypothesis by using the well-known abortion herb Achyranthes bidentata Blume (A. bidentata). Five compounds were separated from the herb root. Among them, ginsenoside Ro was the most potent in inhibiting embryonic implantation within non-cytotoxic concentrations...

The topic of precision medicine is increasingly more prevalent in the general medical literature with oncology research leading the way. Many factors, such as, availability of targeted drugs, advances in laboratory science, and improved information systems, converged to make precision medicine research possible on a large scale at the National Cancer Institute. The resultant big data will spur new kinds of research in the decades to come, but until then, all clinicians are challenged to make sense of an overabundance of information when managing individual patients...
