76 g/L and 18.4% molar yield under shake-flask conditions and 2.5 g/L and 17.4% molar yield under fermenter-controlled conditions from common aromatics that can be derived from lignin. This represents the first example of the direct adipic acid production from model compounds of lignin depolymerization. Renal cell carcinoma (RCC) is increasing in incidence and one third of newly diagnosed cases already are metastatic. The metastatic spread of solid tumors renders RCC incurable by surgical resection and consequently more difficult to treat. New molecular-targeted therapies have played a pivotal role in RCC treatment. Unfortunately, tumors frequently develop resistance to these targeted therapies by activating bypass pathways in which alternative signaling or biochemical pathways are activated in response to targeted inhibition of a signaling pathway, allowing cancer cells to continue to survive. Although the advent of immunotherapy with checkpoint inhibitors has led to significant changes in the treatment landscape for advanced RCC, many issues remain to be resolved. For these reasons, there is an urgent need to develop novel therapies and new treatment paradigms for patients with RCC. Much research has been performed thus far in identifying novel targets and treatment strategies in RCC and many of these currently are under investigation and/or in clinical trials. In this article, we discuss therapeutic options in the management of RCC with a focus on the new therapeutic approaches currently investigated in research and for use in the clinic. We divide these potential novel therapies into five groups nonbiologics, small-molecule drugs, biologics, immunomodulatory therapies, and peptide drugs. We also present some therapeutics and treatment paradigms. Immune checkpoint inhibitors have quickly become a critical component to the management of advanced renal cell carcinoma. These therapies have been approved for patients who are treatment-naive and who have progressed on antiangiogenesis agents. Combinations of immune checkpoint inhibitors with antiangiogenesis agents show significant response rates and prolong survival. Adverse events associated with the use of checkpoint inhibition present unique challenges in the management of patients, and careful considerations are needed when checkpoint inhibitors are combined with antiangiogenesis agents. Nevertheless, the improvement in overall survival associated with these agents indicates that they will remain a vital component of kidney cancer treatment. As early detection and advances in the treatment for renal cell carcinoma continue to lead to excellent oncologic outcomes, the preservation of renal function in kidney cancer patients has emerged as an increasingly important clinical objective. Given that diabetes, hypertension, obesity, cigarette smoking, and aging are independent risk factors for renal cell carcinoma, the corresponding non-neoplastic kidney diseases frequently are present, but often undiagnosed. In addition, the subsequent clinical management of the ensuing chronic kidney disease historically has not included nephrologists. Awareness of these practice gaps remain low among nephrologists, surgeons, and pathologists. This article discusses the common non-neoplastic kidney diseases that are encountered in cancer nephrectomy specimens. The accurate and timely diagnosis of these disorders will result in additional gains in clinical outcomes. There is a unique opportunity for the nephrology community to play a central role in the management of chronic kidney disease that often is present in kidney cancer patients. Renal cell carcinoma is associated with chronic kidney disease as well as with common risk factors including hypertension and diabetes mellitus. Localized renal cell carcinoma is treated surgically and in these cases has a favorable prognosis. In particular, in those individuals with small renal masses (≤4 cm), preservation of kidney function should be prioritized. Postoperative chronic kidney disease or end-stage renal disease prevention should include baseline kidney function and risk factor assessment, nontumor renal biopsy, as well as counseling on treatment options to discuss maximizing kidney function preservation. Postnephrectomy prognosis can be determined with repeat laboratory and clinical assessment. Ultimately, early involvement of the nephrologist in a multidisciplinary team including the urology team will enable the reduction of postsurgical kidney disease related morbidity and potentially mortality. The incidence of kidney cancer has been increasing steadily and, until recently, there was a substantial lack of effective therapies for a cancer that is now among the 10 most common cancers in men and women. During the past 10 years, novel therapies have been developed including antiangiogenic drugs targeting vascular endothelial growth factor and its receptors, immune checkpoint inhibitors, and mammalian target of rapamycin inhibitors that have resulted in a significant improvement in clinical outcomes in a traditionally difficult-to-treat cancer. These new drugs, however, also have important side effects and toxicities that often have an impact on the treatment of these patients. The use of anti-angiogenic drugs often results in the development of hypertension and, less frequently, varying degrees of proteinuria including nephrotic range proteinuria. A variety of agents are used for the treatment of hypertension and proteinuria including blockers of the renin angiotensin system and calcium channel blockers, but there are no randomized clinical trials comparing different therapeutic agents in these patients. selleck compound Immune checkpoint inhibitors have become one of the cornerstones of therapy in kidney cancer, but their use is linked to a variety of side effects that affect almost every organ and resemble autoimmune diseases. In the kidney, these drugs can induce acute interstitial nephritis in close to 5% of patients with varying degrees of severity that in some cases require discontinuation of treatment and systemic treatment with corticosteroids. Although mammalian target of rapamycin inhibitors now also are part of the therapeutic armamentarium available for these patients, all clinical trials have been performed in patients with normal renal function and therefore their effects in patients with abnormal renal function are not known.
