Rising occurrences of various diseases and epidemics have pressurized the already-burdened health system across the globe, and this imposes an unprecedented challenge on our current research in identifying disease-specific biomarkers and molecular targets, in particular for cancers, neurological disorders and unexplained infertility. Despite decades of efforts in deciphering the fundamental biology underlying various diseases at discrete levels using an array of advanced technologies, attempts to identify reliable and disease-indicating markers for detection and biomolecules or cellular structures for targeting are still in vain. This monograph describes and discusses the updated findings in this field with a specific aim to compile ... Read moreprior and recent literature and from there to acquire some insights to facilitate future research to expand options of understanding, detecting and treating diseases. Among the many possible areas of biomedical research, this content comprises two themes: disease biomarkers and molecular targets. The book also covers topics that are more advanced in development to emerging scientific discoveries. In particular, this monograph includes concepts on the renovated use of oncofetal molecules in cancer prediction and treatment, the evolving development in cancer biology at the cellular and molecular levels and the recent involvement on new classes of molecules in diseases. This book renews established concepts in the field, and at the same time leads to important insights for research and development of drugs, diagnostics, and interventions for managing diseases of unmet medical needs.
