Cellular stress response was investigated in two lines of D. virilis: wild type and line with disturbed neurohormonal stress-reaction. Analysis of proteins, synthesized in salivary glands of larvae of both lines under heat stress, revealed malfunction in heat shock reaction of mutant specimen. This malfunction expresses in decreased level of heat shock protein synthesis. Analysis of electrophoretic spectra of proteins from homogenates of imagoes of both lines maintained under normal conditions and those exposed to heat (38 degrees C, 60 min.) revealed correlation between protein spectrum and physiological state of the organism. Interlinear differences by proteins spectra in normal condition, controlled by a single gene (or by block of closely linked genes), were found. The question if there is a common genetic control for the neurohormonal stress-reaction and cellular stress response is discussed.

Fibrosis accounts for approximately one-third of disease-related deaths globally. Current therapies fail to cure fibrosis, emphasizing the need to identify new antifibrotic approaches. Fibrosis is defined by the excessive accumulation of extracellular matrix (ECM) and resultant stiffening of tissue stroma.

Background: Melanocytes protect the body from ultraviolet radiation by synthesizing melanin. Tyrosinase, a key enzyme in melanin production, accumulates in the endoplasmic reticulum (ER) during melanin synthesis, potentially causing ER stress. However, regulating ER function for melanin synthesis has been less studied than controlling Tyrosinase activity.
