Cancer is the main cause of mortality and morbidity worldwide. Although a large variety of therapeutic approaches have been developed and translated into clinical protocols, the toxic side effects of cancer treatments negatively impact patients, allowing cancer to grow. Brassica metabolites are emerging as new weapons for anti-cancer therapeutics. The beneficial role of the consumption of brassica vegetables, the most-used vegetables in the Mediterranean diet, particularly broccoli, in the prevention of chronic diseases, including cardiovascular diseases, diabetes, and obesity, has been well-documented. In this review, we discuss the anti-tumor effects of the bioactive compounds from Brassica vegetables with regard to the compounds and types of cancer against which they show activity, providing current knowledge on the anti-cancer effects of Brassica metabolites against major types of tumors. In addition, we discuss the impacts of industrial and domestic processing on the compounds’ functional properties before their consumption as well as the main strategies used to increase the content of health-promoting metabolites in Brassica plants through biofortification. Finally, the impacts of microbiota on the compounds’ bioactivity are considered. This information will be helpful for the further development of efficacious anti-cancer drugs.

Novel Therapeutic Strategies

From initiation through progression, cancer cells are subjected to a magnitude of endogenous and exogenous stresses, which aid in their neoplastic transformation. Exposure to these classes of stress induces imbalance in cellular homeostasis and, in response, cancer cells employ informative adaptive mechanisms to rebalance biochemical processes that facilitate survival and maintain their existence. Different kinds of stress stimuli trigger epigenetic alterations in cancer cells, which leads to changes in their transcriptome and metabolome, ultimately resulting in suppression of growth inhibition or induction of apoptosis. Whether cancer cells show a protective response to stress or succumb to cell death depends on the type of stress and duration of exposure. A thorough understanding of epigenetic and molecular architecture of cancer cell stress response pathways can unveil a plethora of information required to develop novel anti-cancer therapeutics. The present view highlights current knowledge about alterations in epigenome and transcriptome of cancer cells as a consequence of exposure to different physicochemical stressful stimuli such as reactive oxygen species (ROS), hypoxia, radiation, hyperthermia, genotoxic agents, and nutrient deprivation. Currently, an anti-cancer treatment scenario involving the imposition of stress on target cancer cells is gaining traction to augment or even replace conventional therapeutic regimens. Therefore, a comprehensive understanding of stress response pathways is crucial for devising and implementing novel therapeutic strategies.

Anti Cancer

Over the past decades, anti-cancer treatments have evolved rapidly from cytotoxic chemotherapies to targeted therapies including oral targeted medications and injectable immunooncology and cell therapies. New anti-cancer medications come to markets at increasingly high prices, and health insurance coverage is crucial for patient access to these therapies. State laws are intended to facilitate insurance coverage of anti-cancer therapies.Using Massachusetts as a case study, we identified five current cancer coverage state laws and interviewed experts on their perceptions of the relevance of the laws and how well they meet the current needs of cancer care given rapid changes in therapies. Interviewees emphasized that cancer therapies, as compared to many other therapeutic areas, are unique because insurance legislation targets their coverage. They identified the oral chemotherapy parity law as contributing to increasing treatment costs in commercial insurance. For commercial insurers, coverage mandates combined with the realities of new cancer medications — including high prices and often limited evidence of efficacy at approval — compound a difficult situation. Respondents recommended policy approaches to address this challenging coverage environment, including the implementation of closed formularies, the use of cost-effectiveness studies to guide coverage decisions, and the application of value-based pricing concepts. Given the evolution of cancer therapeutics, it may be time to evaluate the benefits and challenges of cancer coverage mandates.

Histone Deacetylase (HDAC) inhibitors are a relatively new class of anti-cancer agents that play important roles in epigenetic or non-epigenetic regulation, inducing death, apoptosis, and cell cycle arrest in cancer cells. Recently, their use has been clinically validated in cancer patients resulting in the approval by the FDA of four HDAC inhibitors, vorinostat, romidepsin, belinostat and panobinostat, used for the treatment of cutaneous/peripheral T-cell lymphoma and multiple myeloma. Many more HDAC inhibitors are at different stages of clinical development for the treatment of hematological malignancies as well as solid tumors. Also, clinical trials of several HDAC inhibitors for use as anti-cancer drugs (alone or in combination with other anti-cancer therapeutics) are ongoing. In the intensifying efforts to discover new, hopefully, more therapeutically efficacious HDAC inhibitors, molecular modelingbased rational drug design has played an important role. In this review, we summarize four major structural classes of HDAC inhibitors (hydroxamic acid derivatives, aminobenzamide, cyclic peptide and short-chain fatty acids) that are in clinical trials and different computer modeling tools available for their structural modifications as a guide to discover additional HDAC inhibitors with greater therapeutic utility.

Aims: To study various types of gynecological cancers and the available therapeutics to investigate safe and effective drugs. Background: Cancer is the most common cause of mortality throughout the world. When the statistics is considered for gynecological cancers, ovarian, cervical and uterine cancers are among the most prevalent types. They have worst prognosis and the highest mortality rate and by the year 2040 significant increase in mortality rate is predicted. Objective: The major limitation with development of anti-cancer therapeutics for the gynecological cancers are safety of the therapeutics for the developing fetus as well as the mother. Various medicinal classes of natural to synthetic therapeutics have been reported including kinase inhibitors as the most promising category of anti-cancer drugs. Method: A dataset of kinase inhibitory clinically approved anticancer agents was derived through literature review. A QSAR based approach i.e. VEGAQSAR has been applied to evaluate the reproductive and developmental toxicity for the selected class of kinase inhibitors. Result: In the present work, the promising category of anticancer kinase inhibitors has been investigated for its toxicity potential with the help of in silico approach. The anti-cancer kinase inhibitors were categorized based on the found non-toxic or toxic properties towards reproductive and developmental toxicity. Conclusion: Early prediction of the available or proposed anti-cancer therapeutics for their contribution towards developmental and reproductive toxicity is an important criterion for their use in pregnancy associated cancers. The investigation of toxicity profile of available anti-cancer kinase therapeutics will be helpful to design and develop novel and safe anti-cancer drugs in the near future. Other: The study outcomes will benefit the current anticancer drug development efforts.

Background: Cancer is one of the leading causes of an increasing number of death incidences in modern society. As the population increases, there is increased thrust for screening newer anticancer (phytoconstituents) agents to manage cancers. Around 35000 herbal phytoconstituents are obtained from plants, animals and marine sources to create awareness of green therapy in managing, reducing, minimizing side effects of modern chemotherapeutics and radiation therapy. The herbal plants are the richest sources of natural remedies and bioactive compounds that promote medicines' alternative systems as a green approach for managing various cancers. The terpenoids, saponins, volatile oils, and flavonoid phytoconstituents are most efficiently used to manage cancer with minimal side effects. Objective: The objectives of the present study are to investigate the efficacious, potent and safe use of herbal phytoconstituents extracts in the management of cancers and study their mechanism of action through alteration of transcription proteins, blocking G-2/M phase, distortion of tubulin structure, generation of reactive oxygen species, lipid peroxidation, cell cycle arrest, anti-proliferation induced cell apoptosis for target specific cancer treatment. The information was collected from databases such as ScienceDirect, PubMed, Google Scholar, Academia, MedLine, and WoS. Methods: The Literature was surveyed and screened keywords like cancer therapeutics, metastasis, proliferation, cell apoptosis, cell lines, phytoconstituents for cancer management, and related disorders. Results: The findings suggested that the crude extracts act as an antioxidant, free radical scavenger, or anti-aging agent exploited in the management of cancers along with treatment of other infectious diseases like ulcers, gout, liver diseases, respiratory tract infection, renal disorders, blood disorders, CVD, anti-inflammatory and several wound infections. Conclusion: The phytoactive moieties having herbal extracts help improve the compromised immunity status of affected patients and provide measures for scientific studies of newer anticancer agents in herbal industries.

The Rho GTPase family can be classified into classic and atypical members. Classic members cycle between an inactive Guanosine DiPhosphate -bound state and an active Guanosine TriPhosphate-bound state. Atypical Rho GTPases, such as RND1, are predominantly in an active GTP-bound conformation. The role of classic members in oncogenesis has been the subject of numerous studies, while that of atypical members has been less explored. Besides the roles of RND1 in healthy tissues, recent data suggest that RND1 is involved in oncogenesis and response to cancer therapeutics. Here, we present the current knowledge on RND1 expression, subcellular localization, and functions in healthy tissues. Then, we review data showing that RND1 expression is dysregulated in tumors, the molecular mechanisms involved in this deregulation, and the role of RND1 in oncogenesis. For several aggressive tumors, RND1 presents the features of a tumor suppressor gene. In these tumors, low expression of RND1 is associated with a bad prognosis for the patients. Finally, we highlight that RND1 expression is induced by anticancer agents and modulates their response. Of note, RND1 mRNA levels in tumors could be used as a predictive marker of both patient prognosis and response to anticancer agents.

Cell–cell communication is an important mechanism in biological processes. Extracellular vesicles (EVs), also referred to as exosomes, microvesicles, and prostasomes, are microvesicles secreted by a variety of cells. EVs are nanometer-scale vesicles composed of a lipid bilayer and contain biological functional molecules, such as microRNAs (miRNAs), mRNAs, and proteins. In this review, “EVs” is used as a comprehensive term for vesicles that are secreted from cells. EV research has been developing over the last four decades. Many studies have suggested that EVs play a crucial role in cell–cell communication. Importantly, EVs contribute to cancer malignancy mechanisms such as carcinogenesis, proliferation, angiogenesis, metastasis, and escape from the immune system. EVs derived from cancer cells and their microenvironments are diverse, change in nature depending on the condition. As EVs are thought to be secreted into body fluids, they have the potential to serve as diagnostic markers for liquid biopsy. In addition, cells can encapsulate functional molecules in EVs. Hence, the characteristics of EVs make them suitable for use in drug delivery systems and novel cancer treatments. In this review, the potential of EVs as anti-cancer therapeutics is discussed.

Cancer cells of diverse origins express extracellular tumor-specific carbohydrate antigens (TACAs) because of aberrant glycosylation. Overexpressed TACAs on the surface of tumor cells are considered biomarkers for cancer detection and have always been prioritized for the development of novel carbohydrate-based anti-cancer vaccines. In recent years, progress has been made in developing synthetic, carbohydrate-based antitumor vaccines to improve immune responses associated with targeting these specific antigens. Tumor cells also exhaust more energy for proliferation than normal cells, by consuming excessive amounts of glucose via overexpressed sugar binding or transporting receptors located in the cellular membrane. Furthermore, inspired by the Warburg effect, glycoconjugation strategies of anticancer drugs have gained considerable attention from the scientific community. This review highlights a small cohort of recent efforts which have been made in carbohydrate-based cancer treatments, including vaccine design and the development of glycoconjugate prodrugs, glycosidase inhibiting iminosugars, and early cancer diagnosis.
