Researchers identify new therapeutic target for cancer

A protein that may be an unexplored target to develop new cancer therapies has been identified by researchers. The protein, known as kinase suppressor of Ras, or KSR, is a pseudoenzyme that plays a critical role in the transmission of signals in the cell determining whether cells grow, divide, or die.

ahesh Influenza A viruses (IAVs) are a major cause of respiratory illness and are responsible for yearly epidemics associated with more than 500,000 annual deaths globally. Novel IAVs may cause pandemic outbreaks and zoonotic infections with, for example, highly pathogenic avian influenza virus (HPAIV) of the H5N1 and H7N9 subtypes, which pose a threat to public health. Treatment options are limited and emergence of strains resistant to antiviral drugs jeopardize this even further. Like all viruses, IAVs depend on host factors for every step of the virus replication cycle. Host kinases link multiple signaling pathways ...

TronAbstractDysregulation of the mitochondrial apoptotic pathway controlled by members of the Bcl-2 protein family plays a central role in cancer development and resistance to conventional cytotoxic as well as targeted therapies. Hence, selective inhibition of pro-survival Bcl-2 family of proteins to activate apoptosis in malignant cells represents an exciting anti-cancer strategy. The remarkable clinical performance of the selective Bcl-2 antagonist venetoclax has highlighted the potential for ...

InestrosaAbstractCommunication between cells occurs through secreted molecules, among which Wnt ligands play a critical role in balancing cell proliferation, differentiation and cellular homeostasis. The action of Wnt signaling can be modulated at several levels, including posttranslational modification of the Wnt ligands, whose acylation is critical for biological activity. At least three enzymes are necessary for Wnt acylation/deacylation: stearoyl CoA desaturase (SCD), porcupin...

by Masayuki Maeda, Hideaki Yamashita The presence of treatment-resistant cells is an important factor that limits the efficacy of cancer therapy, and the prospect of resistance is considered the major cause of the treatment strategy. Several recent studies have employed mathematical models to elucidate the dynamics of generating resi stant cancer cells and attempted to predict the probability of emerging resistant cells. The purpose of this paper is to present numerical approach to compute the number of resistant cells and the emerging probability of resistance. Stochastic model was designed and developed a method to appr...

Therapeutic implications of germline genetic findings in cancer, Published online: 19 February 2019; doi:10.1038/s41571-019-0179-3The majority of genetically targeted approaches to cancer therapy focus on somatic mutations. However, evidence is accumulating in support of a role for germline genetic alterations in determining responsiveness to treatment. In this Review, the authors summarize the therapeutic potential of knowledge of the germline genome in patients with cancer.

Bahulayan Kunnumakkara : The FBXW7 (F-box with 7 tandem WD40) protein encoded by the gene FBXW7 is one of the crucial components of ubiquitin ligase called Skp1-Cullin1-F-box (SCF) complex that aids in the degradation of many oncoproteins via the ubiquitin-proteasome system (UPS) thus regulating cellular growth. FBXW7 is considered as a potent tumor suppressor as most of its target substrates can function as potential growth promoters, including c-Myc, Notch, cyclin E, c-JUN, and KLF5. Its regulators include p53, C/EBP-δ, Numb, microRNAs, Pin 1, Hes-5, BMI1, Ebp2. Mounting evidence has indicated the involvement ...
