RESUMEN
Cancer stem cells (CSCs) are transformed forms of normal stem cells within heterogeneous mixture of cancer cells. These are mainly responsible for the recurrence of cancer after treatment because of their ability to develop resistance against chemo and radiotherapy due to various factors such as activation of signalling pathways important for self-renewal, DNA repair capacity, microenvironment and expression of ABC transporters. Targeting these mechanisms as potential factors can eliminate CSCs, which eventually decreases cancer recurrence. This review focuses on the characteristics of CSCs, their role in the development of resistance to chemotherapy and radiotherapy along with the therapeutic potential targets for successful elimination of CSC population.

Glycation of proteins is often considered as a method to improve their functional properties for promising applications in wound healing. Furthermore, a marked increase in percentage of radical scavenging activity of the conjugates makes it an effective antioxidant synthetic strategy. A simple conjugation process was employed to develop bovine serum albumin-dextran conjugates (BSA-dextran) using Maillard reaction. Higher electrophoretic mobility and surface charge in the prepared conjugates was observed in native PAGE electrophoresis and zeta potential. Moreover, the fluorescence, FTIR and Raman analysis of the BSA-dextran conjugates shows significant shift in the fluorescence and wavelength as a consequence of conjugate formation. In vitro wound healing assay showed increased cell proliferation and migration effect. These finding suggests that BSA-dextran conjugate could open up a new practical way for exploration in the area of wound healing.
