The present disclosure relates to the technical field of biology, and in particular to a Macrobrachium nipponense Cathepsin L gene and use of dsRNA thereof, including the Macrobrachium nipponense Cathepsin L gene, a gene fragment and the dsRNA thereof, and use of the dsRNA in inhibiting ovary development of Macrobrachium nipponense. The Macrobrachium nipponense Cathepsin L gene is obtained at first with the full-length nucleotide sequence as shown in SEQ ID No. 1 and the amino acid sequence as shown in SEQ ID No. 2. Gene fragments with sequences of SEQ ID No. 3 and SEQ ID No. 8 are obtained by using technologies such as RNA interference, and dsRNA1 and dsRNA2 are synthesized from the two gene fragments. The synthesized dsRNA1 and dsRNA2 are injected into a pericardial cavity of a female Macrobrachium nipponense and the result shows that the dsRNA1 can effectively slow down the ovary development speed of the female Macrobrachium nipponense.

Methods and combinations are provided for controlling the duration of action, in vivo, of matrix-degrading enzymes. The methods and combinations permit temporary in-vivo activation of matrix-degrading enzymes upon administration to the extra cellular matrix (or “ECM”). Matrix-degrading enzymes having a controlled duration of action can be used to treat ECM-mediated diseases or disorders characterized by increased deposition or accumulation of one or more ECM components.

Provided herein are separation moieties that are suitable for use in conjunction with a variety of therapeutic payloads. The separation moieties serve to generate conditionally active macromolecules whereby the macromolecules have reduced or minimal biological activity until the separation moieties are modified under specific conditions.
